Air Quality Information for Students Ages 11 and Up

There are many kinds of air pollution. The Environmental Protection Agency (EPA) calculates the Air Quality Index (AQI) for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution, carbon monoxide, sulfur dioxide, and nitrogen dioxide. Ozone and particle pollution are two common pollutants found in many parts of the country.
