Ecotoxicology is the study of pollutants in ecosystems and consequently the study of the interaction of the one upon the other. Ecosystem processes modify the action of pollutants as surely as pollutants impact upon ecosystems and a properly integrated perspective is hence vital in understanding the various pollution problems which face us all. Following the first edition of this widely acclaimed student text, the book starts with a basic introduction to the principles of community ecology. The chemistry or toxicology student is thus armed with the biological background necessary to see pollutants in an environmental context. Discussions of the effects of pollutants and methods of monitoring pollution are completed by a new chapter which presents some illustrative case studies. This book is an invaluable introduction to this important area for students in Ecology, Toxicology, Environmental Health and Conservation as well as a reference for policy makers, industrialists and environmentalists alike.
