EPA - USA
TOXIC AIR POLLUTANTS • Also known as hazardous air pollutants, are those pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects. EPA is working with state, local, and tribal governments to reduce air toxics releases of 188 pollutants to the environment. • Examples of toxic air pollutants include benzene, which is found in gasoline; perchlorethlyene, which is emitted from some dry cleaning facilities; and methylene chloride, which is used as a solvent and paint stripper by a number of industries. Examples of other listed air toxics include dioxin, asbestos, toluene, and metals such as cadmium, mercury, chromium, and lead compounds.

EPA - USA
AIR QUALITY INDEX ‐ AQI • Clean Air Act ‐ develop nationally uniform index and regulate reporting “Unhealthy” for ozone means same in Lima, OH as Los Angeles, CA. • Includes pollutants with national ambient air quality standards: O3, PM, CO, SO2, NO2 • Based on health effects information from review of standards

EPA - USA
AIR POLLUTION • Air pollution comes from many different sources: stationary sources such as factories, power plants, and smelters and smaller sources such as dry cleaners and degreasing operations; mobile sources such as cars, buses, planes, trucks, and trains; and naturally occurring sources such as windblown dust, and volcanic eruptions, all contribute to air pollution. • Air Quality can be affected in many ways by the pollution emitted from these sources. • These pollution sources can also emit a wide variety of pollutants. The EPA has these pollutants classified as the six principal pollutants (or criteria pollutants‐as they are also known). • These pollutants are monitored by the EPA, as well as national, state and local organizations.

EPA - USA
CLEAN AIR ACT • The Clean Air Act provides the principal framework for national, state, and local efforts to protect air quality. • Under the Clean Air Act, OAQPS is responsible for setting standards, also known as national ambient air quality standards (NAAQS), for pollutants which are considered harmful to people and the environment. • OAQPS is also responsible for ensuring that these air quality standards are met, or attained (in cooperation with state, Tribal, and local governments) through national standards and strategies to control pollutant emissions from automobiles, factories, and other sources.
