Hazardous Air Pollutant Handbook: Measurements, Properties, and Fate in Ambient Air provides a comprehensive review of the 188 compounds and compound classes designated as Hazardous Air Pollutants (HAPs) by the Clean Air Act Amendments of 1990, with a specific focus on their potential presence in ambient air. The relevant chemical and physical properties of the compounds are discussed and tabulated, and suitable methods for their measurement in ambient air are identified. A survey of measurements of ambient HAP concentrations is provided for use in historical comparisons and for evaluating the current human health risks from these chemicals. Finally, the book reviews the atmospheric reactions that control the lifetime and fate of the HAPs in ambient air, and summarizes the current knowledge about their transformation products.
