Organic Chemicals In The Aquatic Environment

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.

Chemical Dynamics in Freshwater Ecosystems reviews the processes that control the distribution and impacts of chemical substances discharged into freshwater aquatic environments. The book focuses on the relationships between chemical emissions and the resulting ambient concentration in water, sediments, fish, benthos, plants, and other components of real aquatic ecosystems. Hydrodynamics, sediment dynamics, chemical fate processes, bioaccumulation, and food-chain transfer are major topics discussed in the book. Case studies and models are used to illustrate how quantitative predictions of chemical dynamics and behavior in the aquatic environment can be made. Chemical Dynamics in Freshwater Ecosystems is an excellent reference for aquatic toxicologists, wildlife toxicologists, wildlife biologists, environmental chemists, governmental regulators, environmental modelers, consultants, and students studying the effects of chemicals on aquatic environments.

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.

There is need in environmental research for a book on fresh waters including rivers and lakes. Compared with other books on the topic, this book has a unique outline in that it follows pollution from sources to impact. Included in the text is the treatment of various tracers, ranging from pathogens to stable isotopes of elements and providing a comprehensive discussion which is lacking in many other books on pollution control of natural waters. Geophysical processes are discussed emphasizing mixing of water, interaction between water and the atmosphere, and sedimentation processes. Important geochemistry processes occurring in natural waters are described as are the processes specific to nutrients, organic pollutants, metals, and pathogens in subsequent chapters. Each of these chapters includes an introduction on the selected groups, followed by the physicochemical properties which are the most relevant to their behavior in natural waters, and the theories and models to describe their speciation, transport and transformation. The book also includes the most up to date information including a discussion on emerging pollutants such as brominated and phosphate flame retardants, perflurochemicals, and pharmaceutical and personal care products. Due to its importance an ecotoxicology chapter has been included featuring molecular biological methods, nanoparticles, and comparison of the basis of biotic ligand model with the Weibull dose-response model. Finally, the last chapter briefly summarizes the regulations on ambient water quality.

A supplement to previous books edited by Afgan and Chau, this publication covers the practical aspects of analytical methodology for trace organics. The book reviews the published work on the occurance, distribution, fate, effect, and environmental impact of specific classes of compounds. Essential background information emphasizing practical aspects of various methods with respect to advantages and disadvantages of the published methods is also discussed.
