Here Is Everything You Need To Know About Air Pollution

What Is Air Pollution?

Air pollution refers to the release of pollutants into the air—pollutants which are detrimental to human health and the planet as a whole. According to the World Health Organization (WHO), each year air pollution is responsible for nearly seven million deaths around the globe. 

Nine out of ten human beings currently breathe air that exceeds the WHO’s guideline limits for pollutants, with those living in low- and middle-income countries suffering the most. In the United States, the Clean Air Act, established in 1970, authorizes the U.S. Environmental Protection Agency (EPA) to safeguard public health by regulating the emissions of these harmful air pollutants.

Air pollution is a global problem. In fact, according to a recent study published in Environmental Science & Technology Letters, many Americans live in areas with high levels of ozone and particulate matter (PM 2.5). Ozone is a key component of smog, which forms when nitrogen oxides (NOx) react with volatile organic compounds (VOCs) in sunlight.

PM 2.5 is small enough to penetrate deep into your lungs and cause serious health problems like asthma attacks, respiratory infections and even premature death from heart disease or lung cancer if inhaled over long periods of time.

Air pollution comes from many sources

What Causes Air Pollution?

Air pollution is a byproduct of energy production and transportation. “Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project, part of the Climate and Clean Energy program at NRDC.

“Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says. “

Another type of air pollution, smog, is then worsened by that increased heat, forming when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants, including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season).

The EPA has identified six common air pollutants: ground-level ozone; particle pollution; carbon monoxide; sulfur dioxide; nitrogen oxides; and lead. Ground-level ozone can harm people with asthma or other respiratory diseases as well as.

Effects of Air Pollution

Air pollution can cause or aggravate a number of health problems, including asthma, lung cancer, heart disease and stroke. Some pollutants also can harm the nervous system and kidneys.

The effects of air pollution on the human body vary depending on the type of pollutant and the length and level of exposure—as well as other factors, including a person’s individual health risks and the cumulative impacts of multiple pollutants or stressors.

A study published in March 2016 in Environmental Health Perspectives found that children exposed to high levels of traffic-related air pollution had a higher risk for developing attention deficit hyperactivity disorder (ADHD) than children who were not exposed. The risk was even greater for boys than for girls.

Smog and soot

Smog and soot are two of the most prevalent types of air pollution, but they’re not the only ones.

There are also gases like ozone (O3) and carbon monoxide; particulates such as sulfates, nitrates, and black carbon; and dozens of other chemicals that can pose health risks when breathed in over long periods of time. These pollutants come from a variety of sources: cars and trucks, factories, power plants, incinerators, engines — generally anything that combusts fossil fuels such as coal, gas or natural gas.

Smog is also known as ground-level ozone. It occurs when emissions from combusting fossil fuels react with sunlight. Soot is made up of tiny particles of chemicals, soil, smoke or dust — in the form of either gas or solids — that are carried in the air. The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines generally anything that combusts fossil fuels such as coal gas or natural gas,” Walke says.
