Polycyclic Hydrocarbons and Cancer, Volume 1: Environment, Chemistry, and Metabolism brings together information from many diverse disciplines in the environmental, chemical, biological, and medical sciences to provide a comprehensive account of the link between polycyclic aromatic hydrocarbons (PAHs) and cancer. This volume consists of 19 chapters divided into seven sections based on the following themes: Energy Sources; Environmental Occurrence and Monitoring; Tobacco Carcinogenesis; Chemistry, Carcinogenicity, and Theory; Metabolism and Activation; Enzymology; and Pharmacokinetics. The first three chapters focus on the energy sources, occurrence and surveillance, and environmental monitoring of PAHs. The discussion then turns to the link between smoking and cancer; the carcinogenicity of 5-methylchrysene; synthesis and reactions of diol epoxides and related metabolites of carcinogenic hydrocarbons; and enzymes of oxygenation. The final chapter is devoted to the pharmacokinetics of chemically reactive metabolites. This book will be of interest to investigators and educators concerned with scientific aspects of PAH research; government officials and elected representatives as well as industry leaders who must confront and solve the problems related to PAHs; and others in various fields such as chemistry, environmental science, biochemistry and enzymology, pharmacology, molecular and cell biology, and genetics.
