Recent studies show that air pollution is a racial issue, and the burden of unhealthy air isn’t equally shared. According to the State of the Air report, 19.8 million people live in counties that failed on all three air pollution measures. These counties disproportionately affect people of color, with African Americans living in failing counties 61% more frequently than white people. Furthermore, black residents were found to be 3.6 times more likely than white residents to live in a county with failing air quality.

Mobile sources

Prior work has examined the impact of traffic emissions on air quality and public health. A nationwide analysis of the effects of traffic emissions on mortality in 2005 suggested that about a quarter of those deaths were attributable to PM2.5. Additional research has pointed to the significant regional health benefits of eliminating motor vehicle trips. Here are some examples of areas that are most affected by air pollution from mobile sources. These areas are characterized by high poverty and overlapping patterns of traffic density and mortality.

While the U.S. Environmental Protection Agency regulates stationary sources, mobile sources include on-road passenger vehicles, construction equipment, and small gardening equipment. Federal legislation requires the EPA to set standards for mobile sources and vehicles. In addition, OTAQ has many programs to help reduce emissions from mobile sources. This website also contains information on OTAQ’s mission and organizational structure. However, the EPA is not required to regulate mobile sources in all areas.

Non-fossil fuel combustion

A new study estimates that reducing emissions from fossil fuels could prevent 50,000 premature deaths and result in over $600 billion in health benefits in the United States annually. The study was published in the GeoHealth journal and outlines the significant health benefits that would be gained from eliminating these pollutants. Fossil fuels are the primary source of carbon dioxide emissions and other air pollutants. By reducing fossil fuel emissions, we would also have the added benefits of lowering air pollution in the United States.

Fossil fuel combustion creates direct and indirect emissions. Indirect emissions are produced during the combustion of fossil fuel in power plants. These emissions are then used in residential and commercial activities, including lighting and appliances. The EPA’s inventory of air pollution from fossil fuels includes emissions from both power plants and industrial processes. Indirect emissions come from sources such as chemical reactions and leaks.

Agricultural noncombustion

In addition to carbon emissions, farm equipment such as tractors and combines emits harmful pollutants into the atmosphere. EPA studies agricultural emissions to set standards to protect public health. In fact, it collaborated with farmers to develop the first nationwide study of air pollution from AFOs. In addition to lowering the number of premature deaths due to agricultural noncombustion, these emissions are responsible for more than 17,000 annual deaths.

Despite the fact that agricultural pollution is the major source of air pollution, regional studies have also shown its importance. The new study examines trends and projections, including agricultural pollution’s role in fine-particle formation. The findings suggest that farms are responsible for more than half of the country’s air pollution, and when combined with other sources of pollution, these emissions contribute to the formation of aerosols.

Other noncombustion emissions

According to the U.S. Environmental Protection Agency (EPA), mobile sources of air pollution are the largest contributors to air pollution in the United States, but industrial emissions are not far behind. Air quality is generally bad in the nation’s largest 22 metropolitan areas, and scientists have documented the negative health effects of emissions pollutants. For example, gases from smokestacks and tailpipes produce ozone, which reacts with sunlight to form smog. This smog irritates the cardiovascular system, exacerbates cardiovascular conditions, and has negative health impacts.

Gasoline is another common air pollutant. Because gasoline is highly flammable and toxic, its vapors contribute to air pollution. Additionally, gasoline burning releases carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons, which are greenhouse gases. Gasoline is used by most consumers in cars, small aircraft, and boats, and by landscape and construction equipment. Some environmental laws focus on gasoline pollution, such as those imposed on new cars.

Wildfires

The relationship between air pollution and wildfires in the United States is complex. The two have been linked since at least the mid-1990s, but the effects of wildfire smoke are most severe on people with heart and lung disease. Among these groups, low-income children in the southern San Joaquin Valley are especially vulnerable. As a result, these children tend to be hospitalized more often during wildfire seasons.

In one study, researchers combined data from monitoring stations in western U.S. and Canada with air quality data from NASA satellites and ERA5 weather data to measure changes in air pollution. They found that smoke plumes are an important indicator of air pollution in a given region, as they are often visible on satellite images. By measuring the amount of smoke in a region, researchers were able to create statistical models for air pollution changes in specific areas.

Extreme heat

The combination of extreme heat and air pollution has devastating public health and economic effects. Congress has the opportunity to take action now by mobilizing around President Biden’s Build Back Better agenda. By investing in federal programs, lawmakers can equip all Americans with the tools they need to survive and thrive in a safe, healthy environment. Listed below are some of the steps Congress can take to help fight the heat and air pollution crisis in the United States.

The burning of fossil fuels is one of the primary causes of global warming. By adding more heat to the atmosphere, this increased temperature pushes extreme temperatures and average temperatures higher. Increasing temperatures cause nighttime low temperatures to rise faster than daytime lows, making them even more difficult to endure. Increasing nighttime temperatures may not only cause heat stroke, but also impair people’s ability to cope with the intense heat.

COVID-19

The study team looked at data from across the United States to determine the impact of COVID-19 on air quality. They looked at the difference in air pollution levels among counties according to urban-rural status and business closures. The study found that the disease is most severe in areas with high levels of air pollution, such as the Midwest and Southern California. The authors suggest that government programs and policies should focus on improving air quality while maintaining environmental protections.

Researchers found that COVID-19 infections were most common among people with chronic illnesses, which means that air pollution may be a contributing factor to COVID-19 hospitalizations. The study authors recommend additional research on the relationship between COVID-19 and air pollution. They also recommend that the government enforce existing protection regulations. They believe that the increased risk is related to air pollution. Regardless of its cause, COVID-19 air pollution is dangerous.

Education

EPA’s recently issued guidelines for schools to avoid areas with high air pollution levels are largely based on regional data. But the study’s findings are consistent with other localized information. In fact, a study conducted in Utah found that students who lived within a mile of a steel mill were 40 percent more likely to miss school than students who did not live nearby. But how can we improve air quality in our schools?

To improve school-age students’ health and educational outcomes, we must increase the amount of evidence-based interventions and policies for air pollution. We must also consider innovative ways to reduce exposure and address cultural and industrial legacies. After all, short-term effects of air pollution may lead to long-term exposures and permanent changes. But what is the best way to deal with the problem? How do we make the right decisions to protect future generations?

Economic benefits

Several studies have demonstrated the economic benefits of reducing air pollution. Lower air pollution concentrations are linked with lower all-cause mortality, cardiovascular disease, and lung cancer. According to the Environmental Protection Agency (EPA), the Clean Air Act has resulted in nearly 370,000 premature deaths and 189,000 fewer hospitalizations for cardiac illnesses every year. The benefits of cleaner air are estimated to be as high as $3.8 trillion per year for the U.S. economy, which is about 32 times greater than the costs of regulations.

The Clean Air Act continues to improve health outcomes by reducing pollution. Fewer premature deaths and illness mean lower medical costs and reduced school absences. Increased worker productivity is another major benefit. Economic benefit of air pollution reductions is evident in many studies published by peer-reviewed institutions. Furthermore, the Clean Air Act has spurred innovation and market development of cleaner technologies. So, while we cannot eliminate pollution in all industrial sectors overnight, it can help in the long run.
