Criteria pollutant: The Clean Air Act requires EPA to set National Ambient Air Quality Standards (NAAQS) for certain pollutants known to be hazardous to human health and the public welfare (for example, damage to forests and degradation of atmospheric visibility). In addition, these pollutants should be ones whose presence in ambient air results from numerous or diverse mobile or stationary sources. EPA has identified and set standards to protect human health and welfare for six pollutants: ozone, carbon monoxide, particulate matter (PM10 and PM2.5), sulfur dioxide, lead, and nitrogen oxide. The term criteria pollutants derives from the requirement that EPA must describe the characteristics and potential health and welfare effects of these pollutants. It is on the basis of such criteria that NAAQS are set or revised.
