"Excellent coverage of current thinking in the science of toxicology."--Willaim A. Toscano, Jr., Tulane University"[O]utstanding in concept and scope. A very strong contribution and a valuable source."--John N. Cooper, Bucknell University"An excellent introductory book to the field of environmental toxicology. Especially valuable is the use of chemical principles to predict biological and environmental effects.
