Organic Micropollutants In Aquatic And Terrestrial Environments

The "Fourth European Symposium on Organic Micropollutants in the Aquatic Environment" was held in Vienna (Austria) from 22 to 24 October 1985. The Symposium was organized wi thin the framework of the Concerted Action COST 641* which is included in the Third R&D Programme on the Environment of the Commission of the European Communities. The aim of the Symposium was to review recent scientific and technical progress in the area of organic micropollutants in the aquatic environment and to present relevant research papers related to analytical methodologies, transformation reactions and transport of organic micropollutants in water, and water treatment processes. A special session was devoted to theoretical aspects and future acti vi ties. Furthermore, special poster sessions were organized where original contributions were presented. This book presents the Proceedings of the Symposium including all review papers, presentations of research papers and extended versions of all posters. We believe that these Proceedings provide a good overview of the activities in this field in Europe. We are confident that it will constitute a valuable contribution to the understanding and solution of the problems posed by organic micropollutants in the aquatic environment. The Commission of the European Communi ties whishes to express its grati tude to the co-organizers of the Symposium, Bundesministerium fUr Gesundheit und Umweltschutz, Wien, and Der Osterreichische Wasserwirtschaftsverband.

Bioremediation, the use of microorganisms to degrade, sequester, or remove environmental contaminants, is an urgent need of our planet for protection and restoration from toxic contaminants. This book not only provides cutting edge information about bioremediation of aquatic and terrestrial habitats, but also highlights the gaps in our knowledge of

Aquatic Pollutants: Transformation and Biological Effects contains the proceedings of the Second International Symposium on Aquatic Pollutants held at Noordwijkerhout (Amsterdam), The Netherlands on September 26-28, 1977. Organized into 47 chapters, this book first describes the aquatic pollutants and their potential biological effects. Subsequent chapters elucidate chemicals with pollution potential; multidetection approach to analysis of organic pollutants in water; volatilization of pollutants from water; microbial transformations of aromatic pollutants; and photochemical transformation of pollutants in water. Other chapters address oxidation of organic compounds in aquatic systems; laboratory microcosms for use in determining pollutant stress; continuous biomonitoring systems for detection of toxic levels of water pollutants; and health aspects of water recycling practices. This book will be useful as a review of existing knowledge in this field. It will also stimulate further thought and research.

Organic Chemicals in the Aquatic Environment draws from the author's experience with a variety of problems dealing with the fate, distribution, and toxicity of organic compounds in the aquatic environment. It discusses the basic issues of chemical analysis, distribution, persistence, and ecotoxicology, with an emphasis on microbial reactions. The necessary input and the difficulties of achieving a rigorous synthesis of the various elements are illustrated with specific examples. The book includes a wide range of structurally diverse compounds as illustration and presents a mechanistic approach to biodegradation and biotransformation. The final chapter addresses the issue of environmental hazard assessment and constructs a strategy for carrying it out.

Chlorinated Organic Micropollutants addresses the sources, environmental cycles, uptake, consequences and control of many of the more important chlorinated organic micropollutants, including PCBs, PCDDs, PCDFs and various chlorinated pesticides, all of which have given widespread cause for concern in relation to their environmental persistence and high toxicity, and their potential for adverse effects on humans and wildlife. Rational decision making over chlorinated organic micropollutants in the environment must be based upon sound science. This volume draws upon the expertise of some of the most distinguished workers in the field, to review current knowledge of the sources, environmental concentrations and pathways, human toxicity and ecotoxicology, and control methods for these groups of compounds. Chlorinated Organic Micropollutants gives a unique and valuable compilation of information on an extremely important group of environmental pollutants. It is fully up-to-date, and will provide a comprehensive overview of this topical subject that will be useful for years to come, to academic, student and professional alike.
