Introduction to Environmental Toxicology focuses on the impacts of chemicals upon ecological systems ranging from the molecular level to the dynamics of ecosystems. This unique book emphasizes the use of toxicity tests and provides important examples. It also details molecular, cellular, and physiological effects. Biodegradation, structure-activity relationships, atmospheric pollutants, and the effects of elemental pollutants on living systems are but a few of the important topics covered in this broad-based text/reference. Environmental toxicology is addressed at the ecosystem level. Significant attention is devoted to examining the difficulties of assessing impacts within ecosystems, reviewing the potential of biomarkers, and noting limits to prediction. Although intended as a text for upper division undergraduates and beginning graduate students, the book will be an excellent reference for anyone in environmental toxicology and chemistry, regulators, risk assessors, environmental consultants, ecologists, and students.

CHOICE Review

Environmental toxicology is a rapidly evolving, multidisciplinary field, increasingly recognized to be important for the development of effective environmental policies. This book, based on courses taught by Landis and Yu, is a well-organized introduction that emphasizes an ecosystem approach. In addition to solid coverage of expected topics such as routes of exposure, modes of action, factors affecting toxicity, biotransformation, and inorganic pollutants, the surveys of laboratory methods for toxicity testing and ecological risk assessment at ecological levels of organization are especially valuable. Questions and references are provided at the end of each chapter, and the EPA document "A Framework or Ecological Risk Assessment" forms an appendix. The focus on ecological systems differentiates this work from Sigmund F. Zakrzewski's Principles of Environmental Toxicology (CH, Jun'92). Landis and Yu's is an excellent resource; however, because it assumes a strong science background, it will be most useful for upper-division undergraduate students through professionals. H. E.
