This book provides a comprehensive examination of all aspects of the ecotoxicology of soil organisms. The book explains how contaminants reach the soil, traces their transport through the soil, and then moves on to examine the effects of contaminants on different groups of soil organisms (e.g., microorganisms, micro- and mesofauna, larger soil animals including vertebrates). The book also considers food chain transfer and discusses risk assessment procedures that are specific to soil conditions. Ecotoxicology of Soil Organisms is the only book to take such a sweeping approach toward soil ecotoxicology. "[Ecotoxicology of Soil Organisms] has an essential place on the book shelves of researchers who are involved in the use of soil organisms to define safe contamination levels and who investigate the effects of contaminants on soil ecosystems...it is a good book in a rapidly changing and important discipline."- Journal of Environmental Quality, September-October 1995
