What are the results?

Particulate matter often consists of solid particles, fine liquid droplets, or condensed liquids adsorbed onto solid particles. Airborne particulate pollution is not made up of a single pollutant as discussed for the other criteria pollutants, but rather a mixture of many different air pollutants. The Georgia Ambient Air Monitoring Program currently monitors for three sizes of particle matter: PM₁₀ (up to 10 microns in diameter), PM_2.5 (up to 2.5 microns in diameter) and PM coarse (PM₁₀ minus PM_2.5).
