Riassunto

Presenting a multidisciplinary perspective in a concise format, Principles of Ecotoxicology, Third Edition discusses the fundamental chemical and ecological nature of pollution processes while identifying the major classes of pollutants and their environmental fate. The first edition was originally created to fill the need for a textbook that covered the basic principles of a developing and wide-ranging field and the second edition expanded on that theme. Keeping the focus on principles over practice that has made each incarnation of this textbook so popular, the third edition brings the text up to date and strengthens coverage in areas that have come to the forefront of the field. The third edition features new material on pollutants that are receiving closer scrutiny, naturally occurring poisons, the history of chemical warfare, population risk assessment, community structure, neonicotinoids, endocrine disruption, and neurotoxicity. A new section on extrapolating from molecular interaction to the consequent population changes highlights the molecules to ecosystem approach and provides the groundwork for discussions on the employment of biomarker strategies in field studies. A major theme of the new material is how the concepts discussed can contribute to improved methods of environmental risk assessment. With updates to every chapter, this text provides essential information for students in easy to use and understandable format.
