Pollution's Impact: Community Health And Wellbeing At Risk

Pollution is a pressing issue that significantly impacts human health and the environment. It can take various forms, such as air, water, and soil pollution, as well as noise and artificial light pollution. Air pollution, caused primarily by energy use and production, is a major contributor to premature deaths and diseases, including cardiovascular and respiratory problems. Outdoor air pollutants easily migrate indoors, and exposure to them can lead to asthma, bronchitis, and heart disease. Additionally, pollution disproportionately affects low-income communities and communities of color due to historical zoning policies and discriminatory lending practices. These communities are often located near highways, major sources of pollution, or polluting facilities, resulting in negative health consequences for their residents. To mitigate the health effects of pollution, interventions at the community and individual levels are necessary.

Pollution increases the risk of cardiovascular and respiratory problems, including asthma, bronchitis, and heart disease

Air pollution has a detrimental impact on the health of communities, increasing the risk of cardiovascular and respiratory problems, including asthma, bronchitis, and heart disease.

Asthma

According to the US Environmental Protection Agency, asthma is a serious and life-threatening chronic respiratory disease that affects over 23 million Americans. Air pollution is known to worsen asthma symptoms and trigger asthma attacks, particularly in children, with an estimated six million children in the United States suffering from the disease. Certain populations, such as African American adolescents, are more vulnerable to the effects of air pollution, even when using asthma therapies like inhalers.

Bronchitis

Bronchitis is an inflammation of the airways in the lungs, causing coughing and mucus production. It can be acute or short-term but can become chronic, leading to long-term respiratory issues. A 2021 study found a significant link between chronic bronchitis and exposure to nitrogen dioxide and black carbon, which are byproducts of burning fossil fuels, such as car engines and burning coal.

Heart Disease

Growing medical evidence links air pollution to heart disease. Short-term exposure to air pollution can increase the risk of heart attack, stroke, arrhythmias, and heart failure in susceptible individuals, including the elderly or those with pre-existing medical conditions. Long-term exposure to air pollution is even more dangerous, as it aids the development and progression of atherosclerosis, a build-up of plaque in the artery walls that causes heart disease.

Cardiovascular and Respiratory Problems

Air pollution is associated with a range of cardiovascular and respiratory issues. Particulate matter (PM), a component of air pollution, can penetrate deep into the lungs and even enter the bloodstream, causing severe health issues. Exposure to PM has been linked to increased respiratory symptoms, decreased lung function, and a higher incidence of chronic cough, bronchitis, and conjunctivitis. Additionally, air pollution can trigger inflammatory responses, create oxidative stress, and impair lung function, making individuals more susceptible to respiratory infections.

Overall, pollution increases the risk of cardiovascular and respiratory problems in communities, affecting both the young and elderly, with certain populations, such as racial and ethnic minorities and low-income communities, facing higher exposure and greater health risks.

Pollutants can easily migrate indoors, with most exposure occurring inside buildings

There are many causes of indoor air pollution. Some are readily recognized due to their smell, but many others go undetected. The smoke from cigarettes, cigars, and pipes is one of the most common—and most dangerous—indoor air pollutants. Tobacco smoke contains more than 7,000 chemicals, including at least 70 that are carcinogenic. When inhaled, these chemicals can also cause chronic obstructive pulmonary disease and other cardiovascular diseases that result in heart attacks and other serious consequences.

Secondhand tobacco smoke is another major indoor air pollutant. In fact, secondhand smoke exposure is estimated to cause about 7,300 lung cancer deaths in non-smoking adults in the United States each year. Further, some reports suggest that tobacco smoke causes ten times more air pollution than diesel car exhaust, making it one of the most severe indoor air pollution sources.

Another common indoor air pollutant is fine particulate matter (PM) from cooking stoves. In developing countries, solid fuels such as wood, coal, and dung are often burned indoors for cooking and heating. Exposure to high levels of PM from indoor cooking stoves has links to a variety of health problems, including respiratory infections, asthma, heart disease, and cancer.

The chemicals in many cleaning products can also pollute indoor air. These chemical products release toxic fumes, which can be harmful when inhaled. Some of these chemicals have been linked to a variety of health problems, including respiratory infections, asthma, and cancer. In addition, many cleaning products contain volatile organic compounds (VOCs), gases that can easily evaporate at room temperature. When VOCs are released into the air, they can cause various short- and long-term health effects, including headaches, nausea, and damage to the liver, kidney, and central nervous system.

Mould is an indoor air pollutant that can cause myriad health problems, including respiratory infections, asthma, and allergies. It grows in damp and humid environments and can be found in a variety of places in the home, such as on walls, floors, ceilings, and basements. Moreover, for those with weakened immune systems or pre-existing conditions like asthma or allergies, mould exposure can exacerbate illnesses and cause serious respiratory infections.

Pet dander is another common indoor air pollution source. Dander can be found in animals' fur, skin, and saliva and is shed by most animals with fur. When pet dander is released into the air, it can be inhaled and cause various respiratory problems, including asthma attacks, hay fever, and other allergies.

Dust is a significant contributor to poor indoor air quality, containing allergen sources and airborne pollutants that can negatively impact health. As outlined above, these microscopic particles, including dust mites, mould spores, and pet dander, can worsen existing respiratory conditions and contribute to a number of other health issues.

Children and adolescents are particularly vulnerable to the health effects of pollution

Children are vulnerable to air pollution from the womb to adulthood. Air pollution has been linked to low birth weight, asthma, reduced lung function, respiratory infections, allergies, and an increased risk of adult chronic diseases. It also affects their lung function and development, especially by ozone and nitrogen dioxide in the short term, and by fine particles in the long term.

In addition, air pollution may affect children's brain development and cognitive abilities and play a role in the development of some types of autism spectrum disorders. Studies have also observed a link between traffic-related air pollution and leukaemia in children.

Furthermore, children tend to spend more time outdoors and are more physically active than adults, potentially increasing their exposure to ambient air pollution. They are also more vulnerable to the effects of indoor air pollution, as they spend most of their time indoors.

Overall, children and adolescents are at greater risk from air pollution exposure, and their health can be significantly impacted by it.

Pollution is linked to social inequalities and income levels, with poorer communities more likely to be exposed

Air pollution is linked to social inequalities and income levels, with poorer communities more likely to be exposed. Low-income communities and minority populations are disproportionately affected by air pollution and are more vulnerable to its adverse health impacts. This is due to various factors, including proximity to pollution sources, limited access to healthcare, and social and economic stressors.

Research has shown that non-white and low-income communities are exposed to more hazardous air pollutants than affluent white communities. For example, a study by Yale University found that areas with larger populations of Hispanics, Asians, and African Americans had higher levels of dangerous compounds such as vanadium, nitrates, and zinc in the air. These communities also face greater health risks, even if their air quality meets federal health standards.

Poorer communities are more likely to be located near industrial plants, transport corridors, and other sources of air pollution. As a result, residents are exposed to higher levels of pollutants, such as nickel, vanadium, and sulfate, which are linked to respiratory and cardiovascular issues. Additionally, low-paying jobs often require physical outdoor labor, further increasing exposure to air pollution.

Limited access to quality and affordable healthcare in these communities further exacerbates the impact of air pollution on health. Social and economic stressors, such as unemployment and poverty, can also make individuals more susceptible to the health risks associated with air pollution. This is evident in areas with high poverty rates, such as the South Bronx in New York City, where asthma rates are significantly higher than the national average.

The interplay between air pollution and socio-economic inequalities is complex. As air pollution increases in an area, housing prices tend to decrease, reinforcing the low-income status of the neighborhood. This cycle perpetuates the exposure of marginalized communities to harmful pollutants and the associated health risks.

Pollution from transport is responsible for a significant proportion of harmful emissions

Transport is a major source of air pollution and is responsible for a significant proportion of harmful emissions. In the United States, the transportation sector is the largest contributor to greenhouse gas emissions, accounting for about 28% of the country's total greenhouse gas emissions. This includes emissions from cars, trucks, buses, airplanes, trains, and ships.

Road transport, in particular, is the largest contributor to climate change within the transport sector. Burning fossil fuels like gasoline and diesel releases carbon dioxide and other greenhouse gases such as methane, nitrous oxide, and hydrofluorocarbons into the atmosphere. These emissions contribute to global warming and climate change, leading to rising temperatures, melting ice caps, and more frequent and intense heat waves.

Transportation emits more than half of the nitrogen oxides in the air, and these emissions have been linked to adverse health impacts. Pollutants from vehicle exhaust, such as particulate matter, volatile organic compounds, nitrogen oxides, carbon monoxide, and sulfur dioxide, pose serious risks to human health. They can cause coughing, itchy eyes, and worsen breathing and lung diseases. Exposure to these pollutants can also increase the risk of respiratory infections, heart disease, stroke, lung cancer, and even premature death.

In addition to the health risks, transport pollution also has social and economic impacts on communities. Low-income communities and communities of color are often disproportionately affected by transport pollution due to factors such as urban segregation and the location of freight centers and roadways. These communities may also lack the resources to adapt to or mitigate the effects of air pollution, making them more vulnerable to its adverse consequences.

To address these issues, governments and organizations are implementing various strategies to reduce emissions from the transportation sector. This includes setting emission standards for vehicles, increasing the use of renewable fuels, and promoting the adoption of electric and zero-emission vehicles. By reducing transport emissions, communities can improve air quality, mitigate climate change, and enhance the health and well-being of their residents.
