Category:Hazardous air pollutants

This category includes hazardous air pollutants, as listed in Section 112 of the U.S. Clean Air Act (1970) and Clean Air Act (1990). The list can be found on Wikipedia at National Emissions Standards for Hazardous Air Pollutants, and on EPA at [1].

This category also includes several air pollutants which are omitted from the Clean Air Act list because they are covered by the EPA's National Ambient Air Quality Standards, namely CO, SO₂, NO_x, O₃, Pb, and Particulate Matter (soot...).
