Toxic Air Contaminant Identification Reports

This page last reviewed March 15, 2010


Assembly Bill 1807 (AB 1807) (Stats. 1983, Ch. 1047; Health and Safety Code section 39650 et seq., Food and Agriculture Code Section 14021 et seq.), enacted in September 1983, sets forth a procedure for the identification and control of toxic air contaminants (TAC) in California. Therefore, the Air Resources Board (ARB or the Board ) is responsible for the identification and control of toxic air contaminants, except in their pesticidal use. The Department of Pesticide Regulation is responsible for the regulation of toxic air contaminants in their pesticidal use.

AB 1807 defines a "toxic air contaminant" as an air pollutant which may cause or contribute to an increase in mortality or an increase in serious illness, or which may pose a present or potential hazard to human health (Health and Safety Code Section 39655a). The ARB prepares identification reports on candidate substances under consideration for listing as toxic air contaminants. The reports and summaries describe the uses of and the extent of emissions in California resulting in public exposure, together with their potential health effects.

The links below provide access to individual reports in PDF. The reports are also available in hard copy. If you have questions, or wish to receive a hard copy, please call the ARB Air Quality Measures Branch at (916) 322-7072.
