With contributions from world-renowned experts in the field, this book explores developments in the transport kinetics, seasonal cycling, accumulation, geochemistry, transformation, and toxicology of arsenic. It details advances in the prevention and control of arsenic and arsenic compounds in the air, soil, and water and offers analytical methods for the detection and study of arsenic in the environment and human body. Providing bioremediation techniques for effective treatment of contaminated water supplies, the book discusses factors that influence the removal of arsenic from water as well as diurnal and seasonal variations in the arsenic concentration of surface water supplies.
