Has recently decreased due to government policy and improved technologies in developed countries. Criteria Pollutants are certain pollutants known to be harmful to human health and welfare and for which National Ambient Air Quality Standards are established. EPA has identified and set standards to protect human health and welfare for ozone, carbon monoxide, particulate matter, sulfur dioxide, lead, and nitrogen oxide..
