内容説明
Mutagenic Effects of Environmental Contaminants investigates the mutagenic consequences of environmental contaminants, such as pesticides, industrials, food additives, drugs, and biologicals, as well as the possible relationships between mutagenesis and carcinogenesis. It describes the monitoring of chemical mutagens in the environment and the ways that genetic mutations cause disease in humans.
Organized into 14 chapters, this volume begins with an overview of the current burden of human genetic disease and the biochemical mechanisms of mutation. It then discusses practical and feasible methods that use a variety of organisms to screen potential mutagenic agents, increased mutation rates in human populations, mutagens that are currently used commercially, and the interrelationships between mutagenicity, carcinogenicity, and teratogenicity. The reader is also introduced to genetic toxicology, detection of chemically induced mutations in experimental animals, and chromosome and somatic mutations in humans.
This book is a valuable resource for scientists, policymakers, and administrators of environmental programs.
