Interest in volatile organic compounds (VOCs) as air pollutants has increased dramatically in recent years. This book covers a number of topical issues concerning VOCs, including stratospheric ozone depletion due to CFCs and the properties of alternative substances; the role of VOCs in the formation of lower atmosphere photochemical ozone; and the problem of the direct toxicity of VOCs such as benzene. This volume reviews current knowledge of volatile organic compounds. It examines sources and atmospheric pathways, atmospheric chemical reactions, and the role of VOCs in both tropospheric photochemistry and the formation of low level ozone. It also looks closely at the sources and concentrations of VOCs indoors, where humans are most likely to be exposed to them. Techniques are described for the calculation of emissions inventories and strategies for control. In addition, the book explores the many government policy matters relating to these compounds. Thus, the book provides readers with in-depth, clearly explained coverage of the many complex scientific and policy issues surrounding VOCs in the atmosphere.
