An element in the earth's crust, an additive in livestock feed. a medicine in early civilization--and the "toxin of toxins" A pervasive part of our natural environment and everyday lives. arsenic has nonetheless earned a niche in history as a substance of diabolical suppleness. Part II of the first comprehensive and up-to-date two-volume study of arsenic, Arsenic in the Environment is a self-contained work that examines arsenic's complex and potentially deadly chemistry, stressing its effect on human health and the surrounding ecosystem. Examining new and unexplored aspects of the toxin, Part II features original research from some of the world's foremost scientists on: Health effects of environmental arsenic Toxicity and metabolism of inorganic and methylated arsenicals Effects of arsenic on DNA synthesis of human lymphocytes Estimation of human exposure to and uptake of arsenic found in drinking water Arsenic hazards to plants and animals Offering a host of subjects of particular interest to toxicologists, medical researchers, public health officials, and industrial hygienists, Part II of Arsenic in the Environment is an indispensable reference that sheds new light on arsenic's unique chemistry as well as its health and environmental effects.
