Addressing the persistent environmental threat of organic chemicals with a fresh approach to degradation and transformation processes, Organic Chemicals in the Environment: Mechanisms of Degradation and Transformation, Second Edition examines a wide range of compounds as well as abiotic and microbiological reactions mediated by microorganisms. The book emphasizes the pathways used and the broad classes of enzymes involved. It provides an overview of experimental procedures with detailed coverage of the organic compounds that are considered to be xenobiotics. The book begins by providing a broad perspective on abiotic and biotic reactions, including the significance of a range of environmental determinants. The following chapters briefly introduce experimental procedures and emphasize those procedures for establishing the structure of metabolites using isotopes and physical methods. Next, the authors outline details of biochemical reactions involved in the biodegradation of the major groups of aliphatic, carbocyclic aromatic, and heterocyclic compounds. They end with coverage of bioremediation that has attracted increasing concern because of the hazard presented by the disposal of unwanted chemicals or by-products from their manufacture. Broad and comprehensive, this book provides a cohesive treatment of the subject. It contains an extensive set of literature references and numerous illustrative figures. The authors use a mechanistic approach with emphasis on the pathways, and the principles that emerge provide a guide not only for specific compounds but also for those having a more remote structural resemblance.

This second edition of a successful title bridging toxicology and environmental chemistry adopts a unique approach that ‘follows’ chemicals on a molecular level, from the environment through the different uptake mechanisms into the body, to the toxic effect. Along the way, this textbook explains the different routes of degradation and metabolism of the different classes of chemicals, linking general chemical properties to their toxicological equivalents. All the chapters have been thoroughly updated and the contents significantly expanded, including for example new chapters on pesticides, food chemicals and pharmaceuticals, as well as sections discussing endocrine disruptors and carcinogenicity assays. This is an essential text for a wide audience ranging from pharmacologists to environmental chemists and toxicologists.

The most exciting technical area in the remediation field today is "in place" or "in situ" technologies. This new book in the popular Geraghty & Miller series provides a single reference source, consolidating information on the various in situ technologies. Each of the primary areas is covered in a separate chapter, allowing for in-depth reviews, including laboratory and pilot plant studies, full-scale design, operation and maintenance, cost analysis, and case histories. Expert accounts are also given emerging in situ technologies. One of the unique features of this new book is its excellent coverage of the geologic foundation and limitations of each of the technologies. Material at the beginning of the book explains the limitations of pump and treatment remediation, and shows how some of these limitations may also apply to in situ technologies. This section provides the reader with a basis on which to analyze and predict the possible success of any new in situ methods that are developed in the future.

The bestselling reference on environmental microbiology—now in a new edition This is the long-awaited and much-anticipated revision of the bestselling text and reference. Based on the latest information and investigative techniques from molecular biology and genetics, this Second Edition offers an in-depth examination of the role of microbiological processes related to environmental deterioration with an emphasis on the detection and control of environmental contaminants. Its goal is to further our understanding of the complex microbial processes underlying environmental degradation, its detection and control, and ultimately, its prevention. Features new to this edition include: A completely new organization with topics such as pathogens in developing countries, effects of genetically modified crops on microbial communities, and transformations of toxic metals Comprehensive coverage of key topics such as bacteria in the greenhouse and low-energy waste treatment New coverage relating core book content to local, regional, and global environmental problems Environmental Microbiology, Second Edition is essential reading for environmental microbiologists and engineers, general environmental scientists, chemists, and chemical engineers who are interested in key current subjects in environmental microbiology. It is also appropriate as a textbook for courses in environmental science, chemistry, engineering, and microbial ecology at the advanced undergraduate and graduate levels.

Basic Concepts of Environmental Chemistry, Second Edition provides a theoretical basis for the behavior and biological effects of natural chemical entities and contaminants in natural systems, concluding with a practical focus on risk assessment and the environmental management of chemicals. The text uses molecular properties such as polarity, water solubility, and vapor pressure as the starting point for understanding the environmental chemistry of various contaminants in soil, water, and the atmosphere. It explains biological processes such as respiration and photosynthesis and their relationship to greenhouse gases. The book then introduces environmental toxicology and describes the distribution, transport, and transformation of contaminants, including PCBs and dioxins, plastics, petroleum and aromatic hydrocarbons, soaps and detergents, and pesticides. The author highlights the relationship between specific chemical properties and their environmental and biological effects. Other topics discussed include partition behavior, fugacity, and genotoxicity, particularly involving carcinogens. The second edition updates the contents and incorporates the latest advances in the field since the 1997 edition was published. It presents an entirely new chapter on metals, which underlines the correlation between metallic properties and their behavior in the environment, as well as new sections on radionuclides and acid drainage water. The chapter on atmospheric chemistry and pollution has been substantially expanded including photochemical smog, the Greenhouse Effect, and pollution processes in the atmosphere and acid rain. The author also adds recent approaches to ecotoxicology, ecological, and human risk assessments to include the probabilistic approach. Basic Concepts of Environmental Chemistry, Second Edition is a practical textbook for teaching students the basic concepts of chemistry in the framework of the environment and a practical reference for anyone involved in the management and disposal of industrial chemicals and emissions, occupational health and safety, and the protection of the natural environment.
