What happens to a chemical once it enters the natural environment?How do its physical and chemical properties influence itstransport, persistence, and partitioning in the biosphere? How donatural forces influence its distribution? How are the answers tothese questions useful in making toxicological and epidemiologicalforecasts? Environmental Chemodynamics, Second Edition introduces readers tothe concepts, tools, and techniques currently used to answer theseand other critical questions about the fate and transport ofchemicals in the natural environment. Like its critically acclaimedpredecessor, its main focus is on the mechanisms and rates ofmovement of chemicals across the air/soil, soil/water, andwater/air interfaces, and on how natural processes work to mobilizechemicals near and across interfaces--information vital toperforming human and ecological risk assessments. Also consistent with the first edition, EnvironmentalChemodynamics, Second Edition is organized to accommodate readersof every level of experience. The first section is devoted totheoretical underpinnings and includes discussions of mass balance,thermodynamics, transport science concepts, and more. The secondsection concentrates on practical aspects, including the movementbetween bed-sediment and water, movement between soil and air, andintraphase chemical behavior. This revised and updated edition of Louis J. Thibodeaux's 1979classic features new or expanded coverage of: * Equilibrium models for environmental compartments * Dry deposition of particles and vapors onto water and soilsurfaces * Chemical profiles in rivers and estuaries, particles and porousmedia * Fate and transport in the atmospheric boundary layer and withinsubterranean media * Chemical exchange between water column and bed-sediment * Intraphase chemical transport and fate This Second Edition of Environmental Chemodynamics also includestwice as many references and 50% more exercises and practiceproblems.

Reviews existing knowledge in the natural and engineering sciences to determine the rates, lifetimes, routes, and reservoirs of chemicals moving through the environment and to estimate the level of exposure to susceptible living and nonliving targets. Uses simple models and ideas as guides in constructing integrated environmental and ecosystem models for simulating chemical movement and fate. Coverage includes phase equilibrium and transport processes; the interphase and intraphase transport process; movement of inorganic and organic chemicals across the air-water interface; desorption of chemicals from the mud-water interface; volatilization of pesticides from air-soil surfaces; and vertical distribution of dissolved, reactive chemicals in stratified waterbodies. Includes numerous problems from current literature and appendices with chemical, physical, transport, and environmental data.

Pollution and its control are now one of the most serious problems in environmental management, affecting localized areas, regions, and, increasingly, the entire ecosphere. Chemistry and Ecotoxicology of Pollution provides a basic understanding of the chemical, toxicological, and ecological factors involved when major classes of pollutants act on natural systems. The nature and effects of these pollutants are examined from the primary level of their sources and chemical properties, through their interactions in the environment, to their ultimate ecological effects on organisms and ecosystems. Pollutants are divided into groups, with similar properties, and then the chemistry and ecotoxicology of each group is defined. More importantly, in collating and evaluating available information on pollution processes, the book develops unifying theories on the fundamental chemical and ecological nature of pollution processes. The book uses a conceptual framework to evaluate the impact of pollutants on the components and functions of natural ecosystems. It is based on the chemical and physical properties of a pollutant, its environmental behavior and fate, exposure to and toxic effects on organisms, their populations, communities, and responses of affected ecosystems. This sequence can be applied to known, potential, and emerging pollutants of concern. As government initiatives for the control of chemicals take greater effects, pollution research, particularly in ecotoxicology, will be further developed. Chemistry and Ecotoxicology of Pollution helps play an important role in determining the future direction of research activities in environmental management and pollution control on a worldwide scale. It is a basic resource for students (e.g. environmental chemistry, ecology, land and water management, environmental or public health, environmental engineering, and sustainability science), scientists, researchers, policy makers, and professionals in need of a clear understanding of the nature and effects of environmental pollution from an ecological perspective.

In the last two decades the EPA and other national andinternational agencies have placed increasingly strict regulationson the manufacture and use of synthetic colorants. The pigment anddye industry has had to develop the technology necessary to analyzeand remediate pollutants in wastewater. Although these efforts haveproduced a considerable volume of information, until now, no singlebook has provided an organized, comprehensive treatment of theenvironmental chemistry of synthetic colorants. Environmental Chemistry of Dyes and Pigments is the firstcomprehensive reference to address the environmental problems posedby synthetic colorants, and to provide a forum for the solutionsproposed by industry, government, and academia. Focusing ondevelopments in the field over the past two decades, it deals withall aspects of colored wastewater treatment, the disposal of dyes,analytical methods, toxicity, and regulatory questions. In its coverage of wastewater treatment, this book addresses boththe most commonly used methods and those specifically designed toaddress pollution problems at the source by analyzing for andremoving dyes and pollutants from wastewater effluent. Throughout,real-world data on a wide variety of dyes and dye intermediates isprovided, as well as cost-effective strategies for dealing withwastewater treatment. In addition, several chapters are devoted to the perspectives ofnational and international experts on regulations governing themanufacture, handling, use, and disposal of synthetic dyes andpigments. The impact these regulations have had on both U.S. andforeign industry is also discussed. A complete, comprehensive, and up-to-date guide to pollutionprevention in the dyestuff and textile industries Environmental Chemistry of Dyes and Pigments is the onlyself-contained volume that focuses on the environmental impact ofsynthetic dyes and pigments. Contributions by international expertsfrom industry, academia, and government make this an indispensablebook for anyone dealing with the environmental problems posed bysynthetic colorants. It covers the entire range of environmentalissues, from waste treatment and analysis to pollution preventionand government regulations. Covers the latest wastewater treatment methods Shows how to use recycling and reusing methods effectively, whilecutting production costs Describes state-of-the-art technology, including the PACT(r)system Explains analysis techniques, including spectrometry andionization Covers legislative issues and the regulatory status of variouscompounds in both the United States and abroad Examines the various pollution prevention programs instituted bygovernment and industry Bridging the gap between industrial interests and environmentalconcerns, Environmental Chemistry of Dyes and Pigments stands as aninvaluable resource for scientists, researchers, and engineers inthe textile and dyestuff industries, and in the environmentalsciences. It is also an extremely useful text for environmentalscience students.
