These OWL resources will help you develop and refine the arguments in your writing.

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

• As air pollution can travel long distance, change in emissions from one region influence air quality and associated premature mortality over others. This research uses ensemble-modeled concentrations of anthropogenic ozone (O3) and fine particulate matter (PM2.5) to quantify avoided premature mortality from 20% emission reductions of 6 regions (i.e. North America (NAM), Europe (EUR), South Asia (SAS), East Asia (EAS), Russia/Belarus/Ukraine (RBU) and the Middle East (MDE)) and 3 sectors (i.e. Power and Industry (PIN), Ground Transportation (TRN) and Residential (RES)) and evaluate the impact of interregional transport of precursor emissions from local (i.e. Kao-Ping air basin (KPAB)) and upwind air basin regions (i.e. North and Chu-Miao Air Basin (NCMAB), Central Air Basin (CTAB), Yun-Chia-Nan Air Basin (YCNAB), and Yi-Lan and Hua-Dong Air Basin (YLHDAB)) on O3 and PM2.5 air quality over KPAB. For health impact assessment, we estimate 290,000 (95% CI: 30,000, 600,000) premature O3-related deaths and 2.8 million (0.5 million, 4.6 million) PM2.5-related premature deaths globally for the baseline year 2010. Reducing emissions from MDE and RBU can avoid more O3-related deaths outside of these regions than within while reducing MDE emissions also avoids more PM2.5-related deaths outside of MDE than within. TRN emissions account for the greatest fraction (26-53% of global emission reduction) of O3-related premature deaths in most regions, except for EAS (58%) and RBU (38%) where PIN emissions dominate. For air quality impact assessment, anthropogenic emissions from upwind and local emissions can contribute 17% and 7% of daily maximum 8-hour O3 concentrations, respectively on the highest O3 day while 36.8% and 26.6% of 24-hour average PM2.5 concentrations, respectively during the high PM2.5 days over KPAB, indicating that the upwind emissions play a significant role in KPAB O3 and PM2.5 concentration. The most effective emission control strategy can be approached by reducing upwind anthropogenic NOX emission along with local VOC emission for O3 while upwind anthropogenic NOX emission along with local primary PM2.5 emission for PM2.5. The result highlights the importance of long-range air pollution transport and suggests that emission reductions can improve air quality and have associated health benefits downwind. Therefore, regional cooperation to reduce air pollution transported over long distances may be desirable.

One of our era's greatest scourges is air pollution, on account not only of its impact on climate change but also its impact on public and individual health due to increasing morbidity and mortality. There are many pollutants that are major factors in disease in humans. Among them, Particulate Matter (PM), particles of variable but very small diameter, penetrate the respiratory system via inhalation, causing respiratory and cardiovascular diseases, reproductive and central nervous system dysfunctions, and cancer. Despite the fact that ozone in the stratosphere plays a protective role against ultraviolet irradiation, it is harmful when in high concentration at ground level, also affecting the respiratory and cardiovascular system. Furthermore, nitrogen oxide, sulfur dioxide, Volatile Organic Compounds (VOCs), dioxins, and polycyclic aromatic hydrocarbons (PAHs) are all considered air pollutants that are harmful to humans. Carbon monoxide can even provoke direct poisoning when breathed in at high levels. Heavy metals such as lead, when absorbed into the human body, can lead to direct poisoning or chronic intoxication, depending on exposure. Diseases occurring from the aforementioned substances include principally respiratory problems such as Chronic Obstructive Pulmonary Disease (COPD), asthma, bronchiolitis, and also lung cancer, cardiovascular events, central nervous system dysfunctions, and cutaneous diseases. Last but not least, climate change resulting from environmental pollution affects the geographical distribution of many infectious diseases, as do natural disasters. The only way to tackle this problem is through public awareness coupled with a multidisciplinary approach by scientific experts; national and international organizations must address the emergence of this threat and propose sustainable solutions.

Approach to the Problem

The interactions between humans and their physical surroundings have been extensively studied, as multiple human activities influence the environment. The environment is a coupling of the biotic (living organisms and microorganisms) and the abiotic (hydrosphere, lithosphere, and atmosphere).

Pollution is defined as the introduction into the environment of substances harmful to humans and other living organisms. Pollutants are harmful solids, liquids, or gases produced in higher than usual concentrations that reduce the quality of our environment.

Human activities have an adverse effect on the environment by polluting the water we drink, the air we breathe, and the soil in which plants grow. Although the industrial revolution was a great success in terms of technology, society, and the provision of multiple services, it also introduced the production of huge quantities of pollutants emitted into the air that are harmful to human health. Without any doubt, the global environmental pollution is considered an international public health issue with multiple facets. Social, economic, and legislative concerns and lifestyle habits are related to this major problem. Clearly, urbanization and industrialization are reaching unprecedented and upsetting proportions worldwide in our era. Anthropogenic air pollution is one of the biggest public health hazards worldwide, given that it accounts for about 9 million deaths per year ( 1 ).

Without a doubt, all of the aforementioned are closely associated with climate change, and in the event of danger, the consequences can be severe for mankind ( 2 ). Climate changes and the effects of global planetary warming seriously affect multiple ecosystems, causing problems such as food safety issues, ice and iceberg melting, animal extinction, and damage to plants ( 3 , 4 ).

Air pollution has various health effects. The health of susceptible and sensitive individuals can be impacted even on low air pollution days. Short-term exposure to air pollutants is closely related to COPD (Chronic Obstructive Pulmonary Disease), cough, shortness of breath, wheezing, asthma, respiratory disease, and high rates of hospitalization (a measurement of morbidity).

The long-term effects associated with air pollution are chronic asthma, pulmonary insufficiency, cardiovascular diseases, and cardiovascular mortality. According to a Swedish cohort study, diabetes seems to be induced after long-term air pollution exposure ( 5 ). Moreover, air pollution seems to have various malign health effects in early human life, such as respiratory, cardiovascular, mental, and perinatal disorders ( 3 ), leading to infant mortality or chronic disease in adult age ( 6 ).

National reports have mentioned the increased risk of morbidity and mortality ( 1 ). These studies were conducted in many places around the world and show a correlation between daily ranges of particulate matter (PM) concentration and daily mortality. Climate shifts and global planetary warming ( 3 ) could aggravate the situation. Besides, increased hospitalization (an index of morbidity) has been registered among the elderly and susceptible individuals for specific reasons. Fine and ultrafine particulate matter seems to be associated with more serious illnesses ( 6 ), as it can invade the deepest parts of the airways and more easily reach the bloodstream.

Air pollution mainly affects those living in large urban areas, where road emissions contribute the most to the degradation of air quality. There is also a danger of industrial accidents, where the spread of a toxic fog can be fatal to the populations of the surrounding areas. The dispersion of pollutants is determined by many parameters, most notably atmospheric stability and wind ( 6 ).

In developing countries ( 7 ), the problem is more serious due to overpopulation and uncontrolled urbanization along with the development of industrialization. This leads to poor air quality, especially in countries with social disparities and a lack of information on sustainable management of the environment. The use of fuels such as wood fuel or solid fuel for domestic needs due to low incomes exposes people to bad-quality, polluted air at home. It is of note that three billion people around the world are using the above sources of energy for their daily heating and cooking needs ( 8 ). In developing countries, the women of the household seem to carry the highest risk for disease development due to their longer duration exposure to the indoor air pollution ( 8 , 9 ). Due to its fast industrial development and overpopulation, China is one of the Asian countries confronting serious air pollution problems ( 10 , 11 ). The lung cancer mortality observed in China is associated with fine particles ( 12 ). As stated already, long-term exposure is associated with deleterious effects on the cardiovascular system ( 3 , 5 ). However, it is interesting to note that cardiovascular diseases have mostly been observed in developed and high-income countries rather than in the developing low-income countries exposed highly to air pollution ( 13 ). Extreme air pollution is recorded in India, where the air quality reaches hazardous levels. New Delhi is one of the more polluted cities in India. Flights in and out of New Delhi International Airport are often canceled due to the reduced visibility associated with air pollution. Pollution is occurring both in urban and rural areas in India due to the fast industrialization, urbanization, and rise in use of motorcycle transportation. Nevertheless, biomass combustion associated with heating and cooking needs and practices is a major source of household air pollution in India and in Nepal ( 14 , 15 ). There is spatial heterogeneity in India, as areas with diverse climatological conditions and population and education levels generate different indoor air qualities, with higher PM 2.5 observed in North Indian states (557–601 μg/m 3 ) compared to the Southern States (183–214 μg/m 3 ) ( 16 , 17 ). The cold climate of the North Indian areas may be the main reason for this, as longer periods at home and more heating are necessary compared to in the tropical climate of Southern India. Household air pollution in India is associated with major health effects, especially in women and young children, who stay indoors for longer periods. Chronic obstructive respiratory disease (CORD) and lung cancer are mostly observed in women, while acute lower respiratory disease is seen in young children under 5 years of age ( 18 ).

Accumulation of air pollution, especially sulfur dioxide and smoke, reaching 1,500 mg/m3, resulted in an increase in the number of deaths (4,000 deaths) in December 1952 in London and in 1963 in New York City (400 deaths) ( 19 ). An association of pollution with mortality was reported on the basis of monitoring of outdoor pollution in six US metropolitan cities ( 20 ). In every case, it seems that mortality was closely related to the levels of fine, inhalable, and sulfate particles more than with the levels of total particulate pollution, aerosol acidity, sulfur dioxide, or nitrogen dioxide ( 20 ).

Furthermore, extremely high levels of pollution are reported in Mexico City and Rio de Janeiro, followed by Milan, Ankara, Melbourne, Tokyo, and Moscow ( 19 ).

Based on the magnitude of the public health impact, it is certain that different kinds of interventions should be taken into account. Success and effectiveness in controlling air pollution, specifically at the local level, have been reported. Adequate technological means are applied considering the source and the nature of the emission as well as its impact on health and the environment. The importance of point sources and non-point sources of air pollution control is reported by Schwela and Köth-Jahr ( 21 ). Without a doubt, a detailed emission inventory must record all sources in a given area. Beyond considering the above sources and their nature, topography and meteorology should also be considered, as stated previously. Assessment of the control policies and methods is often extrapolated from the local to the regional and then to the global scale. Air pollution may be dispersed and transported from one region to another area located far away. Air pollution management means the reduction to acceptable levels or possible elimination of air pollutants whose presence in the air affects our health or the environmental ecosystem. Private and governmental entities and authorities implement actions to ensure the air quality ( 22 ). Air quality standards and guidelines were adopted for the different pollutants by the WHO and EPA as a tool for the management of air quality ( 1 , 23 ). These standards have to be compared to the emissions inventory standards by causal analysis and dispersion modeling in order to reveal the problematic areas ( 24 ). Inventories are generally based on a combination of direct measurements and emissions modeling ( 24 ).

As an example, we state here the control measures at the source through the use of catalytic converters in cars. These are devices that turn the pollutants and toxic gases produced from combustion engines into less-toxic pollutants by catalysis through redox reactions ( 25 ). In Greece, the use of private cars was restricted by tracking their license plates in order to reduce traffic congestion during rush hour ( 25 ).

Concerning industrial emissions, collectors and closed systems can keep the air pollution to the minimal standards imposed by legislation ( 26 ).

Current strategies to improve air quality require an estimation of the economic value of the benefits gained from proposed programs. These proposed programs by public authorities, and directives are issued with guidelines to be respected.

In Europe, air quality limit values AQLVs (Air Quality Limit Values) are issued for setting off planning claims ( 27 ). In the USA, the NAAQS (National Ambient Air Quality Standards) establish the national air quality limit values ( 27 ). While both standards and directives are based on different mechanisms, significant success has been achieved in the reduction of overall emissions and associated health and environmental effects ( 27 ). The European Directive identifies geographical areas of risk exposure as monitoring/assessment zones to record the emission sources and levels of air pollution ( 27 ), whereas the USA establishes global geographical air quality criteria according to the severity of their air quality problem and records all sources of the pollutants and their precursors ( 27 ).

In this vein, funds have been financing, directly or indirectly, projects related to air quality along with the technical infrastructure to maintain good air quality. These plans focus on an inventory of databases from air quality environmental planning awareness campaigns. Moreover, pollution measures of air emissions may be taken for vehicles, machines, and industries in urban areas.

Technological innovation can only be successful if it is able to meet the needs of society. In this sense, technology must reflect the decision-making practices and procedures of those involved in risk assessment and evaluation and act as a facilitator in providing information and assessments to enable decision makers to make the best decisions possible. Summarizing the aforementioned in order to design an effective air quality control strategy, several aspects must be considered: environmental factors and ambient air quality conditions, engineering factors and air pollutant characteristics, and finally, economic operating costs for technological improvement and administrative and legal costs. Considering the economic factor, competitiveness through neoliberal concepts is offering a solution to environmental problems ( 22 ).

The development of environmental governance, along with technological progress, has initiated the deployment of a dialogue. Environmental politics has created objections and points of opposition between different political parties, scientists, media, and governmental and non-governmental organizations ( 22 ). Radical environmental activism actions and movements have been created ( 22 ). The rise of the new information and communication technologies (ICTs) are many times examined as to whether and in which way they have influenced means of communication and social movements such as activism ( 28 ). Since the 1990s, the term “digital activism” has been used increasingly and in many different disciplines ( 29 ). Nowadays, multiple digital technologies can be used to produce a digital activism outcome on environmental issues. More specifically, devices with online capabilities such as computers or mobile phones are being used as a way to pursue change in political and social affairs ( 30 ).

In the present paper, we focus on the sources of environmental pollution in relation to public health and propose some solutions and interventions that may be of interest to environmental legislators and decision makers.

Sources of Exposure

It is known that the majority of environmental pollutants are emitted through large-scale human activities such as the use of industrial machinery, power-producing stations, combustion engines, and cars. Because these activities are performed at such a large scale, they are by far the major contributors to air pollution, with cars estimated to be responsible for approximately 80% of today's pollution ( 31 ). Some other human activities are also influencing our environment to a lesser extent, such as field cultivation techniques, gas stations, fuel tanks heaters, and cleaning procedures ( 32 ), as well as several natural sources, such as volcanic and soil eruptions and forest fires.

The classification of air pollutants is based mainly on the sources producing pollution. Therefore, it is worth mentioning the four main sources, following the classification system: Major sources, Area sources, Mobile sources, and Natural sources.

Major sources include the emission of pollutants from power stations, refineries, and petrochemicals, the chemical and fertilizer industries, metallurgical and other industrial plants, and, finally, municipal incineration.

Indoor area sources include domestic cleaning activities, dry cleaners, printing shops, and petrol stations.

Mobile sources include automobiles, cars, railways, airways, and other types of vehicles.

Finally, natural sources include, as stated previously, physical disasters ( 33 ) such as forest fire, volcanic erosion, dust storms, and agricultural burning.

However, many classification systems have been proposed. Another type of classification is a grouping according to the recipient of the pollution, as follows:

Air pollution is determined as the presence of pollutants in the air in large quantities for long periods. Air pollutants are dispersed particles, hydrocarbons, CO, CO 2 , NO, NO 2 , SO 3 , etc.

Water pollution is organic and inorganic charge and biological charge ( 10 ) at high levels that affect the water quality ( 34 , 35 ).

Soil pollution occurs through the release of chemicals or the disposal of wastes, such as heavy metals, hydrocarbons, and pesticides.

Air pollution can influence the quality of soil and water bodies by polluting precipitation, falling into water and soil environments ( 34 , 36 ). Notably, the chemistry of the soil can be amended due to acid precipitation by affecting plants, cultures, and water quality ( 37 ). Moreover, movement of heavy metals is favored by soil acidity, and metals are so then moving into the watery environment. It is known that heavy metals such as aluminum are noxious to wildlife and fishes. Soil quality seems to be of importance, as soils with low calcium carbonate levels are at increased jeopardy from acid rain. Over and above rain, snow and particulate matter drip into watery ' bodies ( 36 , 38 ).

Lastly, pollution is classified following type of origin:

Radioactive and nuclear pollution , releasing radioactive and nuclear pollutants into water, air, and soil during nuclear explosions and accidents, from nuclear weapons, and through handling or disposal of radioactive sewage.

Radioactive materials can contaminate surface water bodies and, being noxious to the environment, plants, animals, and humans. It is known that several radioactive substances such as radium and uranium concentrate in the bones and can cause cancers ( 38 , 39 ).

Noise pollution is produced by machines, vehicles, traffic noises, and musical installations that are harmful to our hearing.

The World Health Organization introduced the term DALYs. The DALYs for a disease or health condition is defined as the sum of the Years of Life Lost (YLL) due to premature mortality in the population and the Years Lost due to Disability (YLD) for people living with the health condition or its consequences ( 39 ). In Europe, air pollution is the main cause of disability-adjusted life years lost (DALYs), followed by noise pollution. The potential relationships of noise and air pollution with health have been studied ( 40 ). The study found that DALYs related to noise were more important than those related to air pollution, as the effects of environmental noise on cardiovascular disease were independent of air pollution ( 40 ). Environmental noise should be counted as an independent public health risk ( 40 ).

Environmental pollution occurs when changes in the physical, chemical, or biological constituents of the environment (air masses, temperature, climate, etc.) are produced.

Pollutants harm our environment either by increasing levels above normal or by introducing harmful toxic substances. Primary pollutants are directly produced from the above sources, and secondary pollutants are emitted as by-products of the primary ones. Pollutants can be biodegradable or non-biodegradable and of natural origin or anthropogenic, as stated previously. Moreover, their origin can be a unique source (point-source) or dispersed sources.

Pollutants have differences in physical and chemical properties, explaining the discrepancy in their capacity for producing toxic effects. As an example, we state here that aerosol compounds ( 41 – 43 ) have a greater toxicity than gaseous compounds due to their tiny size (solid or liquid) in the atmosphere; they have a greater penetration capacity. Gaseous compounds are eliminated more easily by our respiratory system ( 41 ). These particles are able to damage lungs and can even enter the bloodstream ( 41 ), leading to the premature deaths of millions of people yearly. Moreover, the aerosol acidity ([H+]) seems to considerably enhance the production of secondary organic aerosols (SOA), but this last aspect is not supported by other scientific teams ( 38 ).

Climate and Pollution

Air pollution and climate change are closely related. Climate is the other side of the same coin that reduces the quality of our Earth ( 44 ). Pollutants such as black carbon, methane, tropospheric ozone, and aerosols affect the amount of incoming sunlight. As a result, the temperature of the Earth is increasing, resulting in the melting of ice, icebergs, and glaciers.

In this vein, climatic changes will affect the incidence and prevalence of both residual and imported infections in Europe. Climate and weather affect the duration, timing, and intensity of outbreaks strongly and change the map of infectious diseases in the globe ( 45 ). Mosquito-transmitted parasitic or viral diseases are extremely climate-sensitive, as warming firstly shortens the pathogen incubation period and secondly shifts the geographic map of the vector. Similarly, water-warming following climate changes leads to a high incidence of waterborne infections. Recently, in Europe, eradicated diseases seem to be emerging due to the migration of population, for example, cholera, poliomyelitis, tick-borne encephalitis, and malaria ( 46 ).

The spread of epidemics is associated with natural climate disasters and storms, which seem to occur more frequently nowadays ( 47 ). Malnutrition and disequilibration of the immune system are also associated with the emerging infections affecting public health ( 48 ).

The Chikungunya virus “took the airplane” from the Indian Ocean to Europe, as outbreaks of the disease were registered in Italy ( 49 ) as well as autochthonous cases in France ( 50 ).

An increase in cryptosporidiosis in the United Kingdom and in the Czech Republic seems to have occurred following flooding ( 36 , 51 ).

As stated previously, aerosols compounds are tiny in size and considerably affect the climate. They are able to dissipate sunlight (the albedo phenomenon) by dispersing a quarter of the sun's rays back to space and have cooled the global temperature over the last 30 years ( 52 ).

Air Pollutants

The World Health Organization (WHO) reports on six major air pollutants, namely particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Air pollution can have a disastrous effect on all components of the environment, including groundwater, soil, and air. Additionally, it poses a serious threat to living organisms. In this vein, our interest is mainly to focus on these pollutants, as they are related to more extensive and severe problems in human health and environmental impact. Acid rain, global warming, the greenhouse effect, and climate changes have an important ecological impact on air pollution ( 53 ).

Particulate Matter (PM) and Health

Studies have shown a relationship between particulate matter (PM) and adverse health effects, focusing on either short-term (acute) or long-term (chronic) PM exposure.

Particulate matter (PM) is usually formed in the atmosphere as a result of chemical reactions between the different pollutants. The penetration of particles is closely dependent on their size ( 53 ). Particulate Matter (PM) was defined as a term for particles by the United States Environmental Protection Agency ( 54 ). Particulate matter (PM) pollution includes particles with diameters of 10 micrometers (μm) or smaller, called PM 10 , and extremely fine particles with diameters that are generally 2.5 micrometers (μm) and smaller.

Particulate matter contains tiny liquid or solid droplets that can be inhaled and cause serious health effects ( 55 ). Particles <10 μm in diameter (PM 10 ) after inhalation can invade the lungs and even reach the bloodstream. Fine particles, PM 2.5 , pose a greater risk to health ( 6 , 56 ) ( Table 1 ).

Penetrability according to particle size.

Multiple epidemiological studies have been performed on the health effects of PM. A positive relation was shown between both short-term and long-term exposures of PM 2.5 and acute nasopharyngitis ( 56 ). In addition, long-term exposure to PM for years was found to be related to cardiovascular diseases and infant mortality.

Those studies depend on PM 2.5 monitors and are restricted in terms of study area or city area due to a lack of spatially resolved daily PM 2.5 concentration data and, in this way, are not representative of the entire population. Following a recent epidemiological study by the Department of Environmental Health at Harvard School of Public Health (Boston, MA) ( 57 ), it was reported that, as PM 2.5 concentrations vary spatially, an exposure error (Berkson error) seems to be produced, and the relative magnitudes of the short- and long-term effects are not yet completely elucidated. The team developed a PM 2.5 exposure model based on remote sensing data for assessing short- and long-term human exposures ( 57 ). This model permits spatial resolution in short-term effects plus the assessment of long-term effects in the whole population.

Moreover, respiratory diseases and affection of the immune system are registered as long-term chronic effects ( 58 ). It is worth noting that people with asthma, pneumonia, diabetes, and respiratory and cardiovascular diseases are especially susceptible and vulnerable to the effects of PM. PM 2.5 , followed by PM 10 , are strongly associated with diverse respiratory system diseases ( 59 ), as their size permits them to pierce interior spaces ( 60 ). The particles produce toxic effects according to their chemical and physical properties. The components of PM 10 and PM 2.5 can be organic (polycyclic aromatic hydrocarbons, dioxins, benzene, 1-3 butadiene) or inorganic (carbon, chlorides, nitrates, sulfates, metals) in nature ( 55 ).

Particulate Matter (PM) is divided into four main categories according to type and size ( 61 ) ( Table 2 ).

Types and sizes of particulate Matter (PM).

Gas contaminants include PM in aerial masses.

Particulate contaminants include contaminants such as smog, soot, tobacco smoke, oil smoke, fly ash, and cement dust.

Biological Contaminants are microorganisms (bacteria, viruses, fungi, mold, and bacterial spores), cat allergens, house dust and allergens, and pollen.

Types of Dust include suspended atmospheric dust, settling dust, and heavy dust.

Finally, another fact is that the half-lives of PM 10 and PM 2.5 particles in the atmosphere is extended due to their tiny dimensions; this permits their long-lasting suspension in the atmosphere and even their transfer and spread to distant destinations where people and the environment may be exposed to the same magnitude of pollution ( 53 ). They are able to change the nutrient balance in watery ecosystems, damage forests and crops, and acidify water bodies.

As stated, PM 2.5 , due to their tiny size, are causing more serious health effects. These aforementioned fine particles are the main cause of the “haze” formation in different metropolitan areas ( 12 , 13 , 61 ).

Ozone Impact in the Atmosphere

Ozone (O 3 ) is a gas formed from oxygen under high voltage electric discharge ( 62 ). It is a strong oxidant, 52% stronger than chlorine. It arises in the stratosphere, but it could also arise following chain reactions of photochemical smog in the troposphere ( 63 ).

Ozone can travel to distant areas from its initial source, moving with air masses ( 64 ). It is surprising that ozone levels over cities are low in contrast to the increased amounts occuring in urban areas, which could become harmful for cultures, forests, and vegetation ( 65 ) as it is reducing carbon assimilation ( 66 ). Ozone reduces growth and yield ( 47 , 48 ) and affects the plant microflora due to its antimicrobial capacity ( 67 , 68 ). In this regard, ozone acts upon other natural ecosystems, with microflora ( 69 , 70 ) and animal species changing their species composition ( 71 ). Ozone increases DNA damage in epidermal keratinocytes and leads to impaired cellular function ( 72 ).

Ground-level ozone (GLO) is generated through a chemical reaction between oxides of nitrogen and VOCs emitted from natural sources and/or following anthropogenic activities.

Ozone uptake usually occurs by inhalation. Ozone affects the upper layers of the skin and the tear ducts ( 73 ). A study of short-term exposure of mice to high levels of ozone showed malondialdehyde formation in the upper skin (epidermis) but also depletion in vitamins C and E. It is likely that ozone levels are not interfering with the skin barrier function and integrity to predispose to skin disease ( 74 ).

Due to the low water-solubility of ozone, inhaled ozone has the capacity to penetrate deeply into the lungs ( 75 ).

Toxic effects induced by ozone are registered in urban areas all over the world, causing biochemical, morphologic, functional, and immunological disorders ( 76 ).

The European project (APHEA2) focuses on the acute effects of ambient ozone concentrations on mortality ( 77 ). Daily ozone concentrations compared to the daily number of deaths were reported from different European cities for a 3-year period. During the warm period of the year, an observed increase in ozone concentration was associated with an increase in the daily number of deaths (0.33%), in the number of respiratory deaths (1.13%), and in the number of cardiovascular deaths (0.45%). No effect was observed during wintertime.

Carbon Monoxide (CO)

Carbon monoxide is produced by fossil fuel when combustion is incomplete. The symptoms of poisoning due to inhaling carbon monoxide include headache, dizziness, weakness, nausea, vomiting, and, finally, loss of consciousness.

The affinity of carbon monoxide to hemoglobin is much greater than that of oxygen. In this vein, serious poisoning may occur in people exposed to high levels of carbon monoxide for a long period of time. Due to the loss of oxygen as a result of the competitive binding of carbon monoxide, hypoxia, ischemia, and cardiovascular disease are observed.

Carbon monoxide affects the greenhouses gases that are tightly connected to global warming and climate. This should lead to an increase in soil and water temperatures, and extreme weather conditions or storms may occur ( 68 ).

However, in laboratory and field experiments, it has been seen to produce increased plant growth ( 78 ).

Nitrogen Oxide (NO 2 )

Nitrogen oxide is a traffic-related pollutant, as it is emitted from automobile motor engines ( 79 , 80 ). It is an irritant of the respiratory system as it penetrates deep in the lung, inducing respiratory diseases, coughing, wheezing, dyspnea, bronchospasm, and even pulmonary edema when inhaled at high levels. It seems that concentrations over 0.2 ppm produce these adverse effects in humans, while concentrations higher than 2.0 ppm affect T-lymphocytes, particularly the CD8+ cells and NK cells that produce our immune response ( 81 ).It is reported that long-term exposure to high levels of nitrogen dioxide can be responsible for chronic lung disease. Long-term exposure to NO 2 can impair the sense of smell ( 81 ).

However, systems other than respiratory ones can be involved, as symptoms such as eye, throat, and nose irritation have been registered ( 81 ).

High levels of nitrogen dioxide are deleterious to crops and vegetation, as they have been observed to reduce crop yield and plant growth efficiency. Moreover, NO 2 can reduce visibility and discolor fabrics ( 81 ).

Sulfur Dioxide (SO 2 )

Sulfur dioxide is a harmful gas that is emitted mainly from fossil fuel consumption or industrial activities. The annual standard for SO 2 is 0.03 ppm ( 82 ). It affects human, animal, and plant life. Susceptible people as those with lung disease, old people, and children, who present a higher risk of damage. The major health problems associated with sulfur dioxide emissions in industrialized areas are respiratory irritation, bronchitis, mucus production, and bronchospasm, as it is a sensory irritant and penetrates deep into the lung converted into bisulfite and interacting with sensory receptors, causing bronchoconstriction. Moreover, skin redness, damage to the eyes (lacrimation and corneal opacity) and mucous membranes, and worsening of pre-existing cardiovascular disease have been observed ( 81 ).

Environmental adverse effects, such as acidification of soil and acid rain, seem to be associated with sulfur dioxide emissions ( 83 ).

Lead is a heavy metal used in different industrial plants and emitted from some petrol motor engines, batteries, radiators, waste incinerators, and waste waters ( 84 ).

Moreover, major sources of lead pollution in the air are metals, ore, and piston-engine aircraft. Lead poisoning is a threat to public health due to its deleterious effects upon humans, animals, and the environment, especially in the developing countries.

Exposure to lead can occur through inhalation, ingestion, and dermal absorption. Trans- placental transport of lead was also reported, as lead passes through the placenta unencumbered ( 85 ). The younger the fetus is, the more harmful the toxic effects. Lead toxicity affects the fetal nervous system; edema or swelling of the brain is observed ( 86 ). Lead, when inhaled, accumulates in the blood, soft tissue, liver, lung, bones, and cardiovascular, nervous, and reproductive systems. Moreover, loss of concentration and memory, as well as muscle and joint pain, were observed in adults ( 85 , 86 ).

Children and newborns ( 87 ) are extremely susceptible even to minimal doses of lead, as it is a neurotoxicant and causes learning disabilities, impairment of memory, hyperactivity, and even mental retardation.

Elevated amounts of lead in the environment are harmful to plants and crop growth. Neurological effects are observed in vertebrates and animals in association with high lead levels ( 88 ).

Polycyclic Aromatic Hydrocarbons(PAHs)

The distribution of PAHs is ubiquitous in the environment, as the atmosphere is the most important means of their dispersal. They are found in coal and in tar sediments. Moreover, they are generated through incomplete combustion of organic matter as in the cases of forest fires, incineration, and engines ( 89 ). PAH compounds, such as benzopyrene, acenaphthylene, anthracene, and fluoranthene are recognized as toxic, mutagenic, and carcinogenic substances. They are an important risk factor for lung cancer ( 89 ).

Volatile Organic Compounds(VOCs)

Volatile organic compounds (VOCs), such as toluene, benzene, ethylbenzene, and xylene ( 90 ), have been found to be associated with cancer in humans ( 91 ). The use of new products and materials has actually resulted in increased concentrations of VOCs. VOCs pollute indoor air ( 90 ) and may have adverse effects on human health ( 91 ). Short-term and long-term adverse effects on human health are observed. VOCs are responsible for indoor air smells. Short-term exposure is found to cause irritation of eyes, nose, throat, and mucosal membranes, while those of long duration exposure include toxic reactions ( 92 ). Predictable assessment of the toxic effects of complex VOC mixtures is difficult to estimate, as these pollutants can have synergic, antagonistic, or indifferent effects ( 91 , 93 ).

Dioxins originate from industrial processes but also come from natural processes, such as forest fires and volcanic eruptions. They accumulate in foods such as meat and dairy products, fish and shellfish, and especially in the fatty tissue of animals ( 94 ).

Short-period exhibition to high dioxin concentrations may result in dark spots and lesions on the skin ( 94 ). Long-term exposure to dioxins can cause developmental problems, impairment of the immune, endocrine and nervous systems, reproductive infertility, and cancer ( 94 ).

Without any doubt, fossil fuel consumption is responsible for a sizeable part of air contamination. This contamination may be anthropogenic, as in agricultural and industrial processes or transportation, while contamination from natural sources is also possible. Interestingly, it is of note that the air quality standards established through the European Air Quality Directive are somewhat looser than the WHO guidelines, which are stricter ( 95 ).

Effect of Air Pollution on Health

The most common air pollutants are ground-level ozone and Particulates Matter (PM). Air pollution is distinguished into two main types:

Outdoor pollution is the ambient air pollution.

Indoor pollution is the pollution generated by household combustion of fuels.

People exposed to high concentrations of air pollutants experience disease symptoms and states of greater and lesser seriousness. These effects are grouped into short- and long-term effects affecting health.

Susceptible populations that need to be aware of health protection measures include old people, children, and people with diabetes and predisposing heart or lung disease, especially asthma.

As extensively stated previously, according to a recent epidemiological study from Harvard School of Public Health, the relative magnitudes of the short- and long-term effects have not been completely clarified ( 57 ) due to the different epidemiological methodologies and to the exposure errors. New models are proposed for assessing short- and long-term human exposure data more successfully ( 57 ). Thus, in the present section, we report the more common short- and long-term health effects but also general concerns for both types of effects, as these effects are often dependent on environmental conditions, dose, and individual susceptibility.

Short-term effects are temporary and range from simple discomfort, such as irritation of the eyes, nose, skin, throat, wheezing, coughing and chest tightness, and breathing difficulties, to more serious states, such as asthma, pneumonia, bronchitis, and lung and heart problems. Short-term exposure to air pollution can also cause headaches, nausea, and dizziness.

These problems can be aggravated by extended long-term exposure to the pollutants, which is harmful to the neurological, reproductive, and respiratory systems and causes cancer and even, rarely, deaths.

The long-term effects are chronic, lasting for years or the whole life and can even lead to death. Furthermore, the toxicity of several air pollutants may also induce a variety of cancers in the long term ( 96 ).

As stated already, respiratory disorders are closely associated with the inhalation of air pollutants. These pollutants will invade through the airways and will accumulate at the cells. Damage to target cells should be related to the pollutant component involved and its source and dose. Health effects are also closely dependent on country, area, season, and time. An extended exposure duration to the pollutant should incline to long-term health effects in relation also to the above factors.

Particulate Matter (PMs), dust, benzene, and O 3 cause serious damage to the respiratory system ( 97 ). Moreover, there is a supplementary risk in case of existing respiratory disease such as asthma ( 98 ). Long-term effects are more frequent in people with a predisposing disease state. When the trachea is contaminated by pollutants, voice alterations may be remarked after acute exposure. Chronic obstructive pulmonary disease (COPD) may be induced following air pollution, increasing morbidity and mortality ( 99 ). Long-term effects from traffic, industrial air pollution, and combustion of fuels are the major factors for COPD risk ( 99 ).

Multiple cardiovascular effects have been observed after exposure to air pollutants ( 100 ). Changes occurred in blood cells after long-term exposure may affect cardiac functionality. Coronary arteriosclerosis was reported following long-term exposure to traffic emissions ( 101 ), while short-term exposure is related to hypertension, stroke, myocardial infracts, and heart insufficiency. Ventricle hypertrophy is reported to occur in humans after long-time exposure to nitrogen oxide (NO 2 ) ( 102 , 103 ).

Neurological effects have been observed in adults and children after extended-term exposure to air pollutants.

Psychological complications, autism, retinopathy, fetal growth, and low birth weight seem to be related to long-term air pollution ( 83 ). The etiologic agent of the neurodegenerative diseases (Alzheimer's and Parkinson's) is not yet known, although it is believed that extended exposure to air pollution seems to be a factor. Specifically, pesticides and metals are cited as etiological factors, together with diet. The mechanisms in the development of neurodegenerative disease include oxidative stress, protein aggregation, inflammation, and mitochondrial impairment in neurons ( 104 ) ( Figure 1 ).

Impact of air pollutants on the brain.

Brain inflammation was observed in dogs living in a highly polluted area in Mexico for a long period ( 105 ). In human adults, markers of systemic inflammation (IL-6 and fibrinogen) were found to be increased as an immediate response to PNC on the IL-6 level, possibly leading to the production of acute-phase proteins ( 106 ). The progression of atherosclerosis and oxidative stress seem to be the mechanisms involved in the neurological disturbances caused by long-term air pollution. Inflammation comes secondary to the oxidative stress and seems to be involved in the impairment of developmental maturation, affecting multiple organs ( 105 , 107 ). Similarly, other factors seem to be involved in the developmental maturation, which define the vulnerability to long-term air pollution. These include birthweight, maternal smoking, genetic background and socioeconomic environment, as well as education level.

However, diet, starting from breast-feeding, is another determinant factor. Diet is the main source of antioxidants, which play a key role in our protection against air pollutants ( 108 ). Antioxidants are free radical scavengers and limit the interaction of free radicals in the brain ( 108 ). Similarly, genetic background may result in a differential susceptibility toward the oxidative stress pathway ( 60 ). For example, antioxidant supplementation with vitamins C and E appears to modulate the effect of ozone in asthmatic children homozygous for the GSTM1 null allele ( 61 ). Inflammatory cytokines released in the periphery (e.g., respiratory epithelia) upregulate the innate immune Toll-like receptor 2. Such activation and the subsequent events leading to neurodegeneration have recently been observed in lung lavage in mice exposed to ambient Los Angeles (CA, USA) particulate matter ( 61 ). In children, neurodevelopmental morbidities were observed after lead exposure. These children developed aggressive and delinquent behavior, reduced intelligence, learning difficulties, and hyperactivity ( 109 ). No level of lead exposure seems to be “safe,” and the scientific community has asked the Centers for Disease Control and Prevention (CDC) to reduce the current screening guideline of 10 μg/dl ( 109 ).

It is important to state that impact on the immune system, causing dysfunction and neuroinflammation ( 104 ), is related to poor air quality. Yet, increases in serum levels of immunoglobulins (IgA, IgM) and the complement component C3 are observed ( 106 ). Another issue is that antigen presentation is affected by air pollutants, as there is an upregulation of costimulatory molecules such as CD80 and CD86 on macrophages ( 110 ).

As is known, skin is our shield against ultraviolet radiation (UVR) and other pollutants, as it is the most exterior layer of our body. Traffic-related pollutants, such as PAHs, VOCs, oxides, and PM, may cause pigmented spots on our skin ( 111 ). On the one hand, as already stated, when pollutants penetrate through the skin or are inhaled, damage to the organs is observed, as some of these pollutants are mutagenic and carcinogenic, and, specifically, they affect the liver and lung. On the other hand, air pollutants (and those in the troposphere) reduce the adverse effects of ultraviolet radiation UVR in polluted urban areas ( 111 ). Air pollutants absorbed by the human skin may contribute to skin aging, psoriasis, acne, urticaria, eczema, and atopic dermatitis ( 111 ), usually caused by exposure to oxides and photochemical smoke ( 111 ). Exposure to PM and cigarette smoking act as skin-aging agents, causing spots, dyschromia, and wrinkles. Lastly, pollutants have been associated with skin cancer ( 111 ).

Higher morbidity is reported to fetuses and children when exposed to the above dangers. Impairment in fetal growth, low birth weight, and autism have been reported ( 112 ).

Another exterior organ that may be affected is the eye. Contamination usually comes from suspended pollutants and may result in asymptomatic eye outcomes, irritation ( 112 ), retinopathy, or dry eye syndrome ( 113 , 114 ).

Environmental Impact of Air Pollution

Air pollution is harming not only human health but also the environment ( 115 ) in which we live. The most important environmental effects are as follows.

Acid rain is wet (rain, fog, snow) or dry (particulates and gas) precipitation containing toxic amounts of nitric and sulfuric acids. They are able to acidify the water and soil environments, damage trees and plantations, and even damage buildings and outdoor sculptures, constructions, and statues.

Haze is produced when fine particles are dispersed in the air and reduce the transparency of the atmosphere. It is caused by gas emissions in the air coming from industrial facilities, power plants, automobiles, and trucks.

Ozone , as discussed previously, occurs both at ground level and in the upper level (stratosphere) of the Earth's atmosphere. Stratospheric ozone is protecting us from the Sun's harmful ultraviolet (UV) rays. In contrast, ground-level ozone is harmful to human health and is a pollutant. Unfortunately, stratospheric ozone is gradually damaged by ozone-depleting substances (i.e., chemicals, pesticides, and aerosols). If this protecting stratospheric ozone layer is thinned, then UV radiation can reach our Earth, with harmful effects for human life (skin cancer) ( 116 ) and crops ( 117 ). In plants, ozone penetrates through the stomata, inducing them to close, which blocks CO 2 transfer and induces a reduction in photosynthesis ( 118 ).

Global climate change is an important issue that concerns mankind. As is known, the “greenhouse effect” keeps the Earth's temperature stable. Unhappily, anthropogenic activities have destroyed this protecting temperature effect by producing large amounts of greenhouse gases, and global warming is mounting, with harmful effects on human health, animals, forests, wildlife, agriculture, and the water environment. A report states that global warming is adding to the health risks of poor people ( 119 ).

People living in poorly constructed buildings in warm-climate countries are at high risk for heat-related health problems as temperatures mount ( 119 ).

Wildlife is burdened by toxic pollutants coming from the air, soil, or the water ecosystem and, in this way, animals can develop health problems when exposed to high levels of pollutants. Reproductive failure and birth effects have been reported.

Eutrophication is occurring when elevated concentrations of nutrients (especially nitrogen) stimulate the blooming of aquatic algae, which can cause a disequilibration in the diversity of fish and their deaths.

Without a doubt, there is a critical concentration of pollution that an ecosystem can tolerate without being destroyed, which is associated with the ecosystem's capacity to neutralize acidity. The Canada Acid Rain Program established this load at 20 kg/ha/yr ( 120 ).

Hence, air pollution has deleterious effects on both soil and water ( 121 ). Concerning PM as an air pollutant, its impact on crop yield and food productivity has been reported. Its impact on watery bodies is associated with the survival of living organisms and fishes and their productivity potential ( 121 ).

An impairment in photosynthetic rhythm and metabolism is observed in plants exposed to the effects of ozone ( 121 ).

Sulfur and nitrogen oxides are involved in the formation of acid rain and are harmful to plants and marine organisms.

Last but not least, as mentioned above, the toxicity associated with lead and other metals is the main threat to our ecosystems (air, water, and soil) and living creatures ( 121 ).

In 2018, during the first WHO Global Conference on Air Pollution and Health, the WHO's General Director, Dr. Tedros Adhanom Ghebreyesus, called air pollution a “silent public health emergency” and “the new tobacco” ( 122 ).

Undoubtedly, children are particularly vulnerable to air pollution, especially during their development. Air pollution has adverse effects on our lives in many different respects.

Diseases associated with air pollution have not only an important economic impact but also a societal impact due to absences from productive work and school.

Despite the difficulty of eradicating the problem of anthropogenic environmental pollution, a successful solution could be envisaged as a tight collaboration of authorities, bodies, and doctors to regularize the situation. Governments should spread sufficient information and educate people and should involve professionals in these issues so as to control the emergence of the problem successfully.

Technologies to reduce air pollution at the source must be established and should be used in all industries and power plants. The Kyoto Protocol of 1997 set as a major target the reduction of GHG emissions to below 5% by 2012 ( 123 ). This was followed by the Copenhagen summit, 2009 ( 124 ), and then the Durban summit of 2011 ( 125 ), where it was decided to keep to the same line of action. The Kyoto protocol and the subsequent ones were ratified by many countries. Among the pioneers who adopted this important protocol for the world's environmental and climate “health” was China ( 3 ). As is known, China is a fast-developing economy and its GDP (Gross Domestic Product) is expected to be very high by 2050, which is defined as the year of dissolution of the protocol for the decrease in gas emissions.

A more recent international agreement of crucial importance for climate change is the Paris Agreement of 2015, issued by the UNFCCC (United Nations Climate Change Committee). This latest agreement was ratified by a plethora of UN (United Nations) countries as well as the countries of the European Union ( 126 ). In this vein, parties should promote actions and measures to enhance numerous aspects around the subject. Boosting education, training, public awareness, and public participation are some of the relevant actions for maximizing the opportunities to achieve the targets and goals on the crucial matter of climate change and environmental pollution ( 126 ). Without any doubt, technological improvements makes our world easier and it seems difficult to reduce the harmful impact caused by gas emissions, we could limit its use by seeking reliable approaches.

Synopsizing, a global prevention policy should be designed in order to combat anthropogenic air pollution as a complement to the correct handling of the adverse health effects associated with air pollution. Sustainable development practices should be applied, together with information coming from research in order to handle the problem effectively.

At this point, international cooperation in terms of research, development, administration policy, monitoring, and politics is vital for effective pollution control. Legislation concerning air pollution must be aligned and updated, and policy makers should propose the design of a powerful tool of environmental and health protection. As a result, the main proposal of this essay is that we should focus on fostering local structures to promote experience and practice and extrapolate these to the international level through developing effective policies for sustainable management of ecosystems.

💡 8 Tips for Writing Essays on Pollution

🏆 best pollution topic ideas & essay examples, 🥇 captivating pollution research topics, 🌩️ shocking pollution essay examples and topic ideas, 🎓 simple & easy topics related to pollution, ✅ most interesting pollution topics to write about, ✍️ pollution essay topics for college, ❓ research questions about pollution.

There is a rising interest in ecological awareness and an overall building desire to move towards sustainable living within society. Thus, a pollution essay requires much more than merely outlining cause and effect occurrences.

Tackling a topic that should be both conscientious and demanding may be a difficult task, but with these few tips below, you can quickly address all pollution essay topics. Here are some ideas on how to make your assigned essay more comfortable to write:

Do your research beforehand. This action will help you start your bibliography, which you should begin by writing down every book and article you hope to use.

Additionally, doing so will help you better understand your subject and be more comfortable writing about it. Readers can always feel when writers are too vague because they want to avoid some aspects of a problem.

Introduce your issue from a historical viewpoint. You should explain the origin of your problem, outlining what changes began affecting the environment and why.

Doing so not only allows engaging your readers but also prevents needlessly confusing them by being evasive about your subject.

If some key terms and processes are not common knowledge, then you should explain them. Topics on pollution have tricky terminology, and you should allow your readers to read your essay while on the same level of knowledge as you.

For example, if you are writing about air pollution, then the terms you use may range from “particulate matter” to “hygroscopicity,” depending on the complexity of your essay’s subject.

The pollution essay thesis statement is a guiding line throughout your writing process. Every sentence you write should relate to your central argument and help advance it forward.

From when you start outlining until you write your conclusion and even when revising your draft, you should always ask yourself whether your writing helps you uphold your thesis.

Use credible sources to support your writing. Book and journal titles, research papers, and even interviews with respected scientists are good examples of what you should include in a bibliography.

You may also use pollution essay quotations to demonstrate scientists’ opinions or statistical numbers. When you reference your facts, your readers trust your writing and accept it as credible and truthful, as well as show a good understanding of the subject.

Give your essay an appropriate heading. Your pollution essay titles should clue your readers in on your argument. Using a “talking” title, which explains your subject at a glance, is a useful way of making your essay stand out among others.

If your subject ties together different issues, then you should think about using subheadings to make your essay more readable.

For example, when writing about nonpoint source pollution, you may need to mention its effects on both ocean and forest environments.

Doing so in different sections of your essay may help you structure your thoughts and bring together your arguments for a well-written conclusion.

Read sample essays written by others to help you understand your subject and essay structure better. Doing so will help you be consistent with your chosen citation style and immerse yourself in your research.

However, do not commit an academic offense by plagiarizing from the work of others.

Recent revelations about poor air quality at Melbourne’s Southern Cross Station probably came as no surprise for passengers who have experienced such conditions.

Train platforms, bus terminal and nearby areas have recorded alarmingly poor air quality. In some parts of the station, nitrogen dioxide levels were more than 90 times the World Health Organization’s (WHO) recommended limit . At such levels, considered much higher than medically acceptable , human health is at risk .

Poor air quality in train stations is a concern in many major cities, including Sydney , New York and Boston in the US, and London and Edinburgh in the UK. In some Sydney stations and tunnels, air pollution was up to five times worse than the WHO’s recommended limit.

Poor air quality is a result of fumes from diesel engines, restricted airflow, station design and the wear of train components. These emissions include tiny airborne particles. This fine particulate matter can cause illness and disease . Passengers, workers and nearby residents may all be affected.

Solutions already exist. Investing in technology, alternative fuels, electrification and better management of stations can improve air quality and reduce the health risks. As with COVID, people can also reduce their exposure by wearing suitable face masks , such as P2 and N95 masks.

It’s a worldwide problem

International studies show poor air quality is common in enclosed train and bus stations. Data for most stations from many cities show levels of fine particulate matter exceeded WHO guidelines .

In Sao Paolo, Brazil, a study found “time spent inside a bus terminal can result in an intolerable health risk for commuters”.

A Danish study identified much higherpollution levels of pollutants in and around diesel trains than for electric trains. Inside the diesel trains, levels of ultrafine particulate matter were 35 times higher, black carbon six times higher, nitrogen oxides (NOx) eight times higher, PM2.5 (particles with a diameter of 2.5 micrometres or less, so they can enter the bloodstream) twice as high and benzo(a)pyrene six times higher.

But aren’t trains a more sustainable form of transport?

In terms of sustainability and general urban air quality , trains help reduce emissions and air pollution when compared to cars and trucks in Australia. Trains transport people more efficiently, with a much smaller land, energy and emissions footprint .

The health impacts of air pollution are usually lower for train commuters than those who commute by car. However, the impacts on train commuters depend on location, the fuel used (diesel or electric) and the extent of their exposure to highly polluted air in enclosed and underground stations.

What can be done to improve air quality?

Rail operators can do many things to help passengers breath more easily. These involve both trains and station management.

Train-side interventions include the use of cleaner fuels, more efficient engines and filtering systems, and shifting from diesel to electric trains.

Station-side solutions include exhaust fans, station design and real-time monitoring of air quality. Optimising schedules and operations can reduce train engine idling time. Loading and unloading facilities can be relocated away from congested areas.

Alternative fuels

Train operators have trialled the use of biofuels , typically blended with mineral diesel. Biodiesel and renewable diesel are made from renewable resources and burn cleaner. Biofuels can cut greenhouse gas emissions by up to 86% .

Biodiesel costs nearly the same as mineral diesel, but renewable diesel costs more.

Technology fixes

Exhaust after-treatment systems on diesel engines are a low-cost option. Filters can capture most soot particles. Selective catalytic reduction technology uses a chemical reaction to reduce NOx emissions .

Improving ventilation and air flow within stations can also help limit pollution .

Another option is diesel-hybrid train fleet conversion . Electric traction modules and energy-storage systems recover energy when the train brakes and store it in a battery for later use.

These systems can operate the train when the diesel engines are shut down, for example during boarding. Energy savings can be up to 6,000kWh/day .

The South Australian government has retrofitted trains with these systems. They can cut fuel use by up to 20% and carbon dioxide emissions by 2,400 tonnes a year on the Adelaide Metro.

Electrification

Electric trains produce much less air pollution – around 20-30% less greenhouse gas emissions per passenger kilometre.

Being lighter and more efficient, electric trains are also cheaper to make, maintain and run than diesel trains (with average savings of 20%, 33% and 45% respectively).

Cleaner air saves lives

Estimating health impacts in Australia is difficult due to limited data, but international evidence provides guidance.

Compared to travel on roads, commuters on trains and metros typically have less exposure to air pollution, except for black carbon . Long-term exposure to black carbon typically increases mortality rates even at low levels of ambient air pollution.

At exposure levels close to what is often found in cities, excess lifetime lung cancer mortality is 0.3 per 1,000. For train staff, Danish research estimates black-carbon exposure results in an extra 16 lung cancer deaths per 1,000 individuals over a lifetime (assuming an eight-hour working day). For working conditions over ten years, a six-fold increase in black carbon lifts this rate to 1.9 per 1,000. A ten-fold increase takes it to 3.2 extra deaths per 1,000 .

Short-term exposure to high air pollution is also linked to deaths from kidney disease .

Leadership is needed to protect people and the planet

Some solutions are easy to apply immediately. Others require planning and foresight.

The impacts on rail costs and operations should be balanced against the importance of protecting the health of commuters and staff, as well as cutting emissions.

Active monitoring and transparent reporting of air quality promote public trust. They’re also needed to assess the effectiveness of solutions.

Shifting towards a cleaner rail system is an opportunity for operators and regulators to show vision and leadership by supporting trains as one of the best alternatives to cars and trucks.

Biden-Harris Administration finalizes strongest-ever pollution standards for cars that position U.S. companies and workers to lead the clean vehicle future, protect public health, address the climate crisis, save drivers money

Final standards will expand consumer choice in clean vehicles and build on historic progress in U.S. auto manufacturing under President Biden’s Investing in America agenda

March 20, 2024

WASHINGTON – Today, March 20, the U.S. Environmental Protection Agency announced final national pollution standards for passenger cars, light-duty trucks, and medium-duty vehicles for model years 2027 through 2032 and beyond. These standards will avoid more than 7 billion tons of carbon emissions and provide nearly $100 billion of annual net benefits to society, including $13 billion of annual public health benefits due to improved air quality, and $62 billion in reduced annual fuel costs, and maintenance and repair costs for drivers. The final standards deliver on the significant pollution reductions outlined in the proposed rule, while accelerating the adoption of cleaner vehicle technologies. EPA is finalizing this rule as sales of clean vehicles, including plug-in hybrid and fully electric vehicles, hit record highs last year.

EPA projects an increase in U.S. auto manufacturing employment in response to these final standards, consistent with the broader Biden-Harris Administration commitment to create good-paying, union jobs leading the clean vehicle future. Strong standards have historically contributed to the U.S. leading the world in the supply of clean technologies, with corresponding benefits for American global competitiveness and domestic employment. Since President Biden took office, companies have announced more than $160 billion in investment in U.S. clean vehicle manufacturing and the U.S. auto manufacturing sector has added more than 100,000 jobs.

These standards will provide greater certainty for the auto industry, catalyzing private investment, creating good-paying union jobs, and invigorating and strengthening the U.S. auto industry. Over the next decade, the standards, paired with President Biden’s historic Investing in America agenda and investments in U.S. manufacturing, will set the U.S. auto sector on a trajectory for sustained growth. Additionally, the final standards will lower costs for consumers. Once fully phased in, the standards will save the average American driver an estimated $6,000 in reduced fuel and maintenance over the life of a vehicle.

EPA Administrator Michael S. Regan will join President Biden’s National Climate Advisor Ali Zaidi today at an event in Washington, DC to announce the final standards and how they build on President Biden’s historic climate and economic record. The event will be livestreamed starting at noon EDT.

“With transportation as the largest source of U.S. climate emissions, these strongest-ever pollution standards for cars solidify America’s leadership in building a clean transportation future and creating good-paying American jobs, all while advancing President Biden’s historic climate agenda,” said EPA Administrator Michael S. Regan . “The standards will slash over 7 billion tons of climate pollution, improve air quality in overburdened communities, and give drivers more clean vehicle choices while saving them money. Under President Biden’s leadership, this Administration is pairing strong standards with historic investments to revitalize domestic manufacturing, strengthen domestic supply chains and create good-paying jobs.” 

“President Biden is investing in America, in our workers, and in the unions that built our middle class and established the U.S. auto sector as a leader in the world,” said President Biden’s National Climate Advisor Ali Zaidi . “The President’s agenda is working. On factory floors across the nation, our autoworkers are making cars and trucks that give American drivers a choice – a way to get from point A to point B without having to fuel up at a gas station. From plug-in hybrids to fuel cells to fully electric, drivers have more choices today. Since 2021, sales of these vehicles have quadrupled and prices continue to come down. This growth means jobs, and it means we are moving faster and faster to take on the climate crisis – all thanks to the President’s leadership.”

Statement from United Automobile Workers : “The EPA has made significant progress on its final greenhouse gas emissions rule for light-duty vehicles. By taking seriously the concerns of workers and communities, the EPA has come a long way to create a more feasible emissions rule that protects workers building ICE vehicles, while providing a path forward for automakers to implement the full range of automotive technologies to reduce emissions.”

Light- and Medium-Duty Vehicle Final Standards

The final standards announced today, the “Multi Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles,” build on EPA’s existing emissions standards for passenger cars and light trucks for model years 2023 through 2026. The standards continue the technology-neutral and performance-based design of previous EPA standards for cars, pickups, and vans, and leverage advances in clean car technologies to further reduce both climate pollution and smog- and soot-forming emissions. EPA is finalizing the same standard proposed for MY 2032 while allowing additional time for the auto sector to scale up clean vehicle manufacturing supply chains in the first three years covered by the rule.

Annually, the net benefits to society for the light- and medium-duty final rule are estimated to be $99 billion. The final rule is expected to avoid 7.2 billion tons of CO2 emissions through 2055, roughly equal to four times the emissions of the entire transportation sector in 2021. It will also reduce fine particulate matter and ozone, preventing up to 2,500 premature deaths in 2055 as well as reducing heart attacks, respiratory and cardiovascular illnesses, aggravated asthma, and decreased lung function.

EPA received extensive feedback on the proposed rule, including through written comments, testimony at public hearings, and other stakeholder engagements. The final standards were informed by the best available data in the public record and rigorous technical assessments. Like the proposal, EPA’s final rule gives manufacturers the flexibility to efficiently reduce emissions and meet the performance-based standards through the mix of technologies they decide is best for them and their customers. EPA’s analysis considers a broad suite of available emission control technologies, and projects that consumers will continue to have a wide range of vehicle choices under the final rule, including advanced gasoline vehicles, hybrids, plug-in hybrid electric vehicles, and full battery electric vehicles.

Compared to the existing MY 2026 standards, the final MY 2032 standards represent a nearly 50% reduction in projected fleet average GHG emissions levels for light-duty vehicles and 44% reductions for medium-duty vehicles. In addition, the standards are expected to reduce emissions of health-harming fine particulate matter from gasoline-powered vehicles by over 95%. This will improve air quality nationwide and especially for people who live near major roadways and have environmental justice concerns.

Investing in America’s Clean Transportation Future

The final rule reflects the significant investments in clean vehicle technologies that industry is already making domestically and abroad, as well as ongoing U.S. market shifts and increasing consumer interest in clean vehicles. The Biden-Harris Administration is also directly supporting communities across America in moving towards a cleaner transportation future, including by building a national network of EV chargers and alternative-fuel stations; ensuring domestic manufacturers have the critical minerals and materials they need to make EV batteries; and funding clean transit and clean school buses, with priority for underserved communities. President Biden’s Investing in America agenda is focused on growing the American economy from the bottom up and the middle out – from rebuilding our nation’s infrastructure, to creating a manufacturing and innovation boom, to building a clean-energy economy that will combat climate change and make our communities more resilient.

Here's what leaders are saying about the final rule:

“I’ve always said Michigan automakers are the best in the world. And this is their moment,” said Senator Debbie Stabenow (MI) . “I appreciate EPA’s commitment to engaging with our automakers and autoworkers to develop an ambitious but achievable final rule. It represents an opportunity for union workers to continue to build the vehicles of the future right here in the U.S. and tackle the climate crisis.”

“My priority will always be to protect American jobs and our environment, keep the United States at the forefront of automotive manufacturing, technology, and innovation, and keep our domestic industry strong and competitive,” said Congresswoman Debbie Dingell (MI-06) . “The EPA has worked with all stakeholders to reach this final rule that includes hybrid and electric vehicles, and ensure these goals are achievable. It’s important to protect vehicle choice – the number of available models has doubled in the last three years, and in the last year sticker prices are down 20%. We need to continue to work on making sure that these vehicles are affordable to everyone, that we have the infrastructure in place to make them accessible and practical for consumers, and bring jobs back to the U.S. The bottom line is that the future of the industry must be created in America and driven by American workers, and we are all committed to working together toward that future.”

“The future is electric. Automakers are committed to the EV transition – investing enormous amounts of capital and building cutting edge battery electric vehicles, plug-in hybrids, traditional hybrids and fuel cell vehicles that drive efficiency and convert petroleum miles to electric miles,” said John Bozzella, President and CEO, Alliance for Automotive Innovation . “Consumers have tons of choices. But pace matters. Moderating the pace of EV adoption in 2027, 2028, 2029 and 2030 was the right call because it prioritizes more reasonable electrification targets in the next few (very critical) years of the EV transition. These adjusted EV targets – still a stretch goal – should give the market and supply chains a chance to catch up. It buys some time for more public charging to come online, and the industrial incentives and policies of the Inflation Reduction Act to do their thing. And the big one? The rules are mindful of the importance of choice to drivers and preserves their ability to choose the vehicle that’s right for them.”

“This is a day to celebrate American achievement. The step EPA is taking today will slash climate pollution and air pollution,” said Amanda Leland, Executive Director of Environmental Defense Fund . “It will bring more jobs for workers, more choices and more savings for consumers, and a healthier future for our children. The U.S. has leapt forward in the global race to invest in clean vehicles, with $188 billion and nearly 200,000 jobs on the way. Jobs in communities across the country, in places like Michigan, Nevada, and Kentucky. These clean car standards will help supercharge economic expansion and make America stronger.”

“These standards make clear that securing America’s global leadership in manufacturing and securing a better future are 100% aligned,” said Albert Gore, Executive Director of the Zero Emission Transportation Association . “We have everything we need today to meet and exceed this standard, and that means more of the vehicles sold in America will be made in America.”

President Biden’s Investing in America Agenda Provides the Single Largest Industrial Decarbonization Investment in the Nation’s History, Driving $20+ Billion in Total Investment to Revitalize Manufacturing Communities and Create and Maintain Good-Paying Jobs 

WASHINGTON, D.C. — As part of President Biden’s Investing in America  agenda , the U.S. Department of Energy (DOE) today announced up to $6 billion for 33 projects across more than 20 states to decarbonize energy-intensive industries, reduce industrial greenhouse gas emissions, support good-paying union jobs, revitalize industrial communities, and strengthen the nation’s manufacturing competitiveness. Funded by the President’s Bipartisan Infrastructure Law and Inflation Reduction Act, the projects will create and maintain tens of thousands of high-quality jobs and help accelerate the commercial-scale demonstration of emerging industrial decarbonization technologies crucial to meeting the Biden-Harris Administration's climate and domestic manufacturing goals.  

The projects will focus on the highest emitting industries where decarbonization technologies will have the greatest impact, including aluminum and other metals, cement and concrete, chemicals and refining, iron and steel, and more. Together, the projects are expected to reduce the equivalent of more than 14 million metric tons of carbon dioxide (CO2) emissions each year—an amount equivalent to the annual emissions of 3 million gasoline-powered cars. Many of the projects will deploy first-in-the-nation emissions-reducing technologies that have the potential for sector-wide adoption and transformation, multiplying the magnitude of the emissions cuts and supporting the future of U.S. manufacturing. Today’s announcement is the largest investment in industrial decarbonization in American history, helping to position American manufacturers and workers to lead the global clean energy economy.  

“Spurring on the next generation of decarbonization technologies in key industries like steel, paper, concrete, and glass will keep America the most competitive nation on Earth,” said U.S. Secretary of Energy Jennifer M. Granholm. “Thanks to President Biden’s industrial strategy, DOE is making the largest investment in industrial decarbonization in the history of the United States. These investments will slash emissions from these difficult-to-decarbonize sectors and ensure American businesses and American workers remain at the forefront of the global economy.” 

This transformative federal investment will help strengthen local economies and create and maintain tens of thousands of good-paying, high-quality jobs—particularly those that support worker organizing and collective bargaining. As part of President Biden’s efforts to build an equitable and inclusive clean energy future, each project is also expected to develop and ultimately implement a comprehensive Community Benefits Plan that ensures meaningful community and labor engagement. Nearly 80% of the projects are located in a disadvantaged community, as defined by President Biden’s Justice40 Initiative , offering a significant opportunity to invest in good jobs and clean air in communities that have experienced years of divestment. 

The industrial sector contributes nearly one-third of the nation’s overall greenhouse gas emissions. This transformative federal investment is matched by the selected projects to leverage more than $20 billion in total to demonstrate commercial-scale decarbonization solutions needed to move the industrial sector toward net-zero emissions. Funded projects will cut carbon emissions by an average of 77%. The industrial sector’s unique and complex decarbonization challenges require equally unique and innovative decarbonization solutions that leverage multiple pathways including energy efficiency, electrification, and alternative fuels and feedstocks such as clean hydrogen. The projects announced today are part of the Industrial Demonstrations Program , managed by DOE’s Office of Clean Energy Demonstrations (OCED), and will help strengthen America’s manufacturing and industrial competitiveness. Funding for these projects includes $489 million from the Bipartisan Infrastructure Law and $5.47 billion from the Inflation Reduction Act. 

Decarbonizing Energy- and Emissions-Intensive Industries The 33 projects selected for award negotiations represent difficult-to-decarbonize industries, including seven chemicals and refining projects, six cement and concrete projects, six iron and steel projects, five aluminum and metals projects, three food and beverage projects, three glass projects, two process heat-focused projects, and one pulp and paper project.  

An overview of selected projects broken down by industry include:  

• Chemicals and Refining : The seven selected chemicals and refining projects demonstrate how one of the world’s largest industries can turn its carbon intensity from a liability into an advantage, increase circularity, and onshore critical supply chains for clean fuels and key electric vehicle components. These projects plan to demonstrate opportunities to upcycle captured carbon to value-added products, create high-quality fuels and materials from recycled products, and replace fossil-fired, high-heat processes with decarbonized fuels. Together, the seven projects would create products like clean fuels for the marine sector, electrolytes for electric vehicle batteries, and high-quality plastics.  
• Cement and Concrete : The six selected cement and concrete projects plan to demonstrate a comprehensive set of technologies capable of eliminating all CO2 emissions from today’s plants while setting the stage for a future where cement—one of the single largest sources of CO2 emissions globally—can be net-negative. These game-changing projects will revolutionize a sector that has relied on emissions-intensive processes for millennia. From capturing and sequestering the emissions from one of the largest cement plants in the U.S. to pioneering chemistry changes to mitigate emissions at their source, DOE’s investments can fundamentally transform cement—the world’s most abundant man-made material and a building block of our world’s infrastructure. Together, the projects will develop new pathways for making traditional Portland cement with lower or zero emissions and to pioneer new materials and new mixtures that can drive the sector to zero emissions.  
• Iron and Steel : The six selected iron and steel projects plan to demonstrate emerging technologies, including some of the world’s first clean hydrogen-fueled direct reduced ironmaking facilities, which can eliminate the vast majority of steelmaking emissions. The projects will help decarbonize iron and steelmaking and enable the industry to phase out more traditional carbon-intensive production methods that rely on coal. This investment is expected to help create products like high grades of steel for the automotive industry, while solidifying the nation’s position as the global leader in low-carbon iron and steel products.  
• Aluminum and Metals : The five selected aluminum and metals projects include a major capital injection to decarbonize and revitalize the U.S. primary aluminum industry along with world-leading recycling approaches for both aluminum and copper. After decades of decline, these investments lay the groundwork for a potential rebound of this critical sector. These investments aim to improve U.S. industry’s competitiveness and efficiency while simultaneously decarbonizing and onshoring supply chains for materials critical for defense and energy sectors. In addition to the high-purity aluminum needed for the defense and energy sectors, the selections include projects that would create recycled aluminum for the food and beverage industry and copper for semiconductors and electric vehicles.  
• Food and Beverage : The three selected food and beverage projects will demonstrate highly replicable energy efficiency and electrification solutions for low- to medium-temperature process heat across 16 locations. These projects can increase consumer awareness around embodied emissions by decarbonizing products that Americans consume every day like ice cream, ketchup, and BBQ sauce.  
• Glass : The three selected glass projects plan to validate electric/fuel hybrid furnaces producing low-emission glass bottles, tableware, and food packaging. This suite of projects will help decarbonize high-temperature heat and set a roadmap for other heat-intensive industrial processes.  
• Process Heat : These two projects plan to validate the use of electric boilers and electric steam production to reduce emissions associated with process heating across a wide range of industries. By demonstrating applicability across sectors, these projects will chart a path for addressing one of the biggest challenges in the industrial sector—heat-related emissions. 
• Pulp and Paper : The one selected pulp and paper project aims to improve energy efficiency by using a novel membrane for an important separations process instead of heat. This technology is highly replicable for many applications, including chemicals and critical materials.

Laying the Foundation of an Inclusive Clean Energy Future  The Biden-Harris Administration is dedicated to working in partnership with communities and industries to build an equitable clean energy economy that benefits every American. As part of the Administration’s commitments to invest in America’s workforce, support high-quality American jobs, advance environmental and energy justice, and strengthen tribal energy sovereignty, each project was required to develop and ultimately implement a comprehensive Community Benefits Plan —which will be informed by early and meaningful community and labor engagements in each region. Applicants were required to describe how their proposals would provide the greatest benefit to the greatest number of people in a facility’s location, recognizing the opportunity this funding provides to address pollution for those disproportionately affected by industrial sector emissions and begin remediating existing social, economic, and health burdens.  

To kickstart ongoing engagement around these projects, OCED will hold a series of national and regional virtual briefings to provide information on the selected projects, introduce OCED’s approach to clean energy demonstrations, and provide opportunities for industry and communities to engage further on specific projects of interest.

Selection for award negotiations is not a commitment by DOE to issue an award or provide funding. Before funding is issued, DOE and the selected applicants will undergo a negotiation process, and DOE may cancel negotiations and rescind the selection for any reason during that time. Lead applicants also may change during the award negotiations process. If awarded, OCED will evaluate these projects through a phased approach to project management that includes “go/no-go” decision points between each project phase where DOE reviews and evaluates implementation progress, including community benefits.
