Category: Air Toxics Completed Studies

The Environmental Protection Agency (EPA) has identified 187 hazardous air pollutants (HAPs) that are associated with numerous adverse health effects including cancer and neurological, reproductive, developmental, and other health problems. These pollutants come from a wide variety of industrial, residential, and mobile sources and the health risk exposure thresholds associated with them are continually updated according to the most current toxicological and epidemiological research. The following studies, including ongoing as well as future projects, have been undertaken to gain a better understanding of the concentration and sources of these pollutants.
