Ecotoxicology Of Organic Contaminants

This book presents an integrated approach to understanding environmental contamination problems through the use of techniques from environmental chemistry, toxicology, ecology, and ecotoxicology. Basing much of his information on his 21 years of experience in the field, the author proposes innovative strategies for studying the environmental fate of contaminants, evaluating the effects, and producing scientific criteria for environmental safety. The book is clearly written, with all terms defined and equations explained with examples of their application. Weak points in the present knowledge are pointed out and discussed. An extensive list of references is provided for individuals who wish to delve deeper into the subject.

ENVIRONMENTAL MANAGEMENT SERIES The current expansion of both public and scientific interest in environ mental issues has not been accompanied by a commensurate production of adequate books, and those which are available are widely variable in approach and depth. The Environmental Management Series has been established with a view to co-ordinating a series of volumes dealing with each topic within the field in some depth. It is hoped that this Series will provide a uniform and quality coverage and that, over a period of years, it will build up to form a library of reference books covering most of the major topics within this diverse field. It is envisaged that the books will be of single, or dual, authorship, or edited volumes as appropriate for respective topics. The level of presentation will be advanced, the books being aimed primarily at a research/consultancy readership. The coverage will include all aspects of environmental science and engineering pertinent to man agement and monitoring of the natural and man-modified environment, as well as topics dealing with the political, economic, legal and social con siderations pertaining to environmental management. J. CAIRNS and R.M. HARRISON v Preface The behaviour and effects of chemicals in our environment is a fascinating subject for scientific investigation. Furthermore, an understanding of these processes is of fundamental importance in our modern world, and should enable us to understand and limit the adverse effects of pollutants.

Difficult to measure accurately and deal with effectively, organic pollutants continue to be a major hazard in the environment. Significantly expanded, the second edition of Organic Pollutants: An Ecotoxicological Perspective describes the mechanistic basis of ecotoxicology, using major groups of pollutants as illustrative examples, and explores th

Organic pollutants continue to be a major hazard in the environment. Often difficult to measure accurately and to deal with effectively, these compounds feature more and more prominently in courses on environmental toxicology and environmental sciences. This much needed book is a companion to the highly praised Principles of Ecotoxicology. It covers organic pollutants in greater depth and detail than has been covered in a textbook before. The first part covers issues such as: chemical warfare metababolism of pollutants in animals and plants environmental fate, and effects within ecosystems This is followed by discussion of particular pollutants such as: organochloride insecticides PCBs dioxins organometallic compounds polycyclic aromatic hydrocarbons anticoagulant rodenticides amongst others. The book concludes with coverage of ecotoxicity testing, biomarkers and bioassays and future prospects for improved assessment of the dangers these compounds pose. It breaks new ground in offering a concise source of information on these compounds at a level suitable for senior undergraduates and postgraduates. Professionals working within the fields of environmental toxicology and environmental science will also find it a valuable reference.

Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.

Completely revised and updated, Fundamentals of Ecotoxicology, Second Edition presents a treatment of ecotoxicology ranging from molecular to global perspectives. The authors focus first on lower levels of organization and then extend their discussion to include landscape, regional, and biospheric topics, imparting a perspective as broad as the the problems facing practicing professionals. See what's new in this edition: A comprehensive chapter on the nature, transport, and fate of major classes of contaminants in terrestrial, freshwater, and marine systems Side bars containing vignettes by leaders in the field let you benefit from the experience of diverse practitioners in the field An appendix covering European environmental regulations The authors detail key contaminants of concern, explore their fate and cycling in the biosphere, and discuss bioaccumulation and the effects of contaminants at increasing levels of ecological organization. They cover regulatory aspects of the field in separate chapters that address the technical issues of risk assessment and discuss key U.S. and European legislation in the appendices. Complete with study questions, a detailed glossary, and vignettes by various experts exploring special topics in ecotoxicology, Fundamentals of Ecotoxicology, Second Edition is an ideal introductory textbook for both undergraduate- and graduate-level courses, as well as a valuable reference for professionals.

The term ecotoxicology is the branch of toxicology concerned with the study of toxic effects, caused by natural or synthetic pollutants, to the constituents of ecosystems, animal (including human), vegetable and microbial. This book discusses the ecotoxicological effects of pharmaceuticals in the environment; the effects of various ecotoxicants on nematodes; salinity threats to agricultural productivity; sorption and the ecological risk assessment of non-ionic organic contaminants; and the application of ecotoxicological tools in the assessment, monitoring of Brazilian waters; and others.
