Air Toxic Pollutants

The air we breathe can become contaminated with pollutants from a variety of natural and manmade sources. Since federal legislation involving ambient air quality was enacted in 1970, air pollution control has focused on "criteria" air pollutants, including sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOx), ozone (O3), lead (Pb), and particulate matter (PM), which are primarily by-products of burning fossil fuel. In recent years, however, the focus of ambient air quality has begun to shift and now includes not only criteria air pollutants, but "toxic" air pollutants. Toxic air pollutants are also referred to as "air toxics" or "hazardous air pollutants" (HAPs) and are defined as those pollutants that are suspected of causing cancer or other serious health conditions, or to cause adverse environmental impacts. more …
