Introduction To Ecotoxicology

Environmental pollution is one of the most serious threats to the future health of our planet. A wide and ever increasing range of chemicals from industry, agriculture, medicine and a host of other sources continue to contribute to the earth's chemical load. Governments have encountered great difficulties responding to the crucial and immediate need for effective management.As a result, the new science of ecotoxicology has developed, which provides a broad conceptual framework for evaluating the effects of chemicals in natural ecosystems.This book is aimed principally at undergraduate students who have completed basic courses in both chemistry and biology. It takes a broad view of ecotoxicology starting with the nature, properties and behaviour of environmental toxicants, and extends to dose/response relationships and effects on organisms, populations, communities and ecosystems. Importantly, it also addresses environmental management areas such as biomarkers, biomonitoring, ecological risk assessment and the ecotoxicology and management of chemicals.The book provides an invaluable overview of the subject for students taking courses in ecotoxicology and environmental pollution, as well as wider degree programmes in biology, ecology, wildlife management, environmental science, environmental impact assessment, toxicology, pollution, chemical engineering, civil engineering, sanitation engineering and related subjects.
