Air Pollution Control Program

Common Air Pollutants

The Environmental Protection Agency has set certain permissible levels, known as the National Ambient Air Quality Standards, for six common air pollutants. These levels, or standards, are based on what concentration of a specific pollutant it would take to become a health or environmental hazard. The Missouri Department of Natural Resources maintains a system of air monitors across the state to check the levels of these six common air pollutants as well as many other pollutants.

More detail about each of the six common air pollutants is available by clicking on the pollutant.
