Air pollutants which are not covered by ambient air quality standards but which, as defined in the Clean Air Act, may reasonably be expected to cause or contribute to irreversible illness or death. Such pollutants include asbestos, beryllium, mercury, benzene, coke oven emissions, radionuclides, and vinyl chloride.
Any air pollutant listed as such in Title III of the 1990 Clean Air Act Amendments. These are chemicals that have the potential to cause serious health effects. HAPs are released by mobile sources and industrial sources. Also referred to as air toxics. Also see "Clean Air Act."
Chemicals that cause adverse health effects including cancer, birth defects, nervous system damage, and possibly death. Potential sources of HAPs may include some printers, drycleaners, and vehicles. Hazardous Material - A material that because of its quantity, concentration, or physical, chemical, or infectious characteristics, may pose a threat to human health and the environment.
Chemicals that cause adverse health effects including cancer, birth defects, nervous system damage, and possibly death. HAPs are listed in the Federal Clean Air Act.
A list of 188 compounds and classes of compounds contained in Section 112 of the Clean Air Act. US Environmental Protection Agency (EPA) is required to develop MACT (maximum achievable control technology) standards for any facility that is classified as a “major source†of HAPs. EPA has authority to add or remove compounds from the HAP list.
(1) Chemicals that cause serious health and environmental effects, (2) According to law, a pollutant to which no ambient air quality standard is applicable and that may cause or contribute to an increase in mortality or in serious illness.
Air pollutants identified in the Clean Air Act Amendments of 1990 as reasonably expected to cause or contribute to irreversible illness or death. Such pollutants include asbestos, beryllium, mercury, benzene, coke oven emissions, radionuclides, and vinyl chloride. A total of 188 hazardous air pollutants are listed in section 112(b) of the Clean Air Act, as amended in 1990. There are no ambient air quality standards for these pollutants.
One of the chemicals listed in section 112(b) of the Clean Air Act Amendments of 1990. Hazardous air pollutants are pollutants known or suspected to cause cancer or other serious health effects or adverse environmental effects. Hazardous air pollutants are regulated by the U.S. Environmental Protection Agency using technology-based standards.
airborne chemicals that cause serious health and environmental effects. Hazardous air pollutants are released by sources such as chemical plants, dry cleaners, printing plants, and motor vehicles.
Hazardous Air Pollutants (HAPs) refers to the 189 chemicals and chemical categories listed in section 112(b) of the United States Clean Air Act. Under the Act, a major source of HAPs is defined as one that emits 10 tons/yr. of any single chemical on the list, or 25 tons/yr. of any combination of these chemicals.
Chemicals that cause serious health and environmental effects. Health effects include cancer, birth defects, nervous system problems and death due to massive accidental releases such as occurred at the pesticide plant in Bhopal, India. HAPs are released by sources such as chemical plants, dry cleaners, printing plants, and motor vehicles (cars, trucks, buses, etc.)
