Polycyclic Aromatic Hydrocarbons (PAH): A Candidate Toxic Air Contaminant

摘要

The State of California's Air Resources Board has classified PAH (polycyclic aromatic hydrocarbons) as a candidate toxic air contaminant (TAC). The report was prepared as background information to help determine whether PAH should be actively reviewed for possible identification as a TAC. The report consists of the following sections: (1) A summary of basic facts regarding PAH, (2) Chemistry and monitoring (sampling and analysis) methods, (3) Studies of ambient air for PAH, (4) A health effects summary, and (5) References. Ambient data are provided for overall PAH, naphthalene, benzo(a)pyrene, particular nitro-PAHs, and mutagenic density. Most of the data for emission sources and ambient concentrations are for California air.
