Air Pollutants
The Clean Air Act identifies common air pollutants that are found all over the United States and can harm health, the environment or cause property damage.
These include:
- Carbon Monoxide
- Ozone
- Particulate Matter (PM10) and (PM2.5)
- Sulfur Oxides
The United States Environmental Protection Agency (EPA) has established National Ambient Air Quality Standards (NAAQS) for each of these pollutants. If the air quality in a geographic area meets the NAAQS, it is called an attainment area; areas that do not meet the NAAQS are called nonattainment areas and must develop comprehensive state plans to reduce pollutant concentrations to a safe level.
