Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, and the individual's health status and genetics. [130] The most common sources of air pollution include particulates and ozone (often from burning fossil fuels), [145] nitrogen dioxide, and sulfur dioxide. Children aged less ...
The six criteria air pollutants were the first set of pollutants recognized by the United States Environmental Protection Agency as needing standards on a national level. [5] The Clean Air Act requires the EPA to set US National Ambient Air Quality Standards (NAAQS) for the six CAPs. [ 6 ]
Clean Air Act standards. Under the Clean Air Act, the National Ambient Air Quality Standards (NAAQS) are developed by the Environmental Protection Agency (EPA) for six common air pollutants, also called "criteria pollutants": particulates; smog and ground-level ozone; carbon monoxide; sulfur oxides; nitrogen oxides; and lead.

Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems.
Since the EPA first started regulating clean air in the 1970s, emissions of the most common air pollutants have dropped by almost 80%. But around Houston, there's still a long way to go. Each year ...
The index aims to help the public easily understand the air quality and protect people's health. The CAI is on a scale from 0 to 500, which is divided into six categories. The higher the CAI value, the greater the level of air pollution. Of values of the five air pollutants, the highest is the CAI value.
For the study, researchers at the University of Birmingham in England used a research kitchen to cook a chicken breast and measured particulate matter and volatile organic compounds (VOCs) given ...
