Health Effects Notebook for Hazardous Air Pollutants

Detailed information about the health effects of hazardous air pollutants (HAPs) is available in separate fact sheets, for nearly every HAP specified in the Clean Air Act Amendments of 1990. These substances include certain volatile organic chemicals, pesticides, herbicides, and radionuclides that present tangible hazard, based on scientific studies of exposure to humans and other mammals.  There is uncertainty in the precise degree of hazard, and readers are cautioned that the fact sheets may be revised as additional data become available. The available fact sheets are listed below, alphabetically by chemical name, along with the Chemical Abstract Service Number (CAS No.), where available.
