This fully-updated new edition incorporates both the common concepts associated with environmental health along with new, emerging, and controversial issues associated with environmental threats to human health. Emphasis is placed on biological, chemical, and physical sources of pollution, and the methods of controlling or limiting those exposures. Careful attention is paid to presenting a balanced view representing opposing scientific views on major issues ranging from "The Greenhouse Effect" to reproductive problems associated with endocrine disruptors. A companion website supplements the material with full-color figures, continuously updated breaking information, useful links, and more.
