Intro to Environmental Toxicology: Impacts of Chemicals Upon Ecological Systems

Front Cover
CRC-Press, 1995 - Science - 328 pages
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.
