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.

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.

Rising concern in recent years over the possible adverse environmental consequences of the use of chemicals has led to a steady increase in national activity towards greater regulation, as well as voluntary agreements with manufacturers for risk management of certain products. This book begins by reviewing the current framework of legislation for the regulation of chemicals in the UK and then reports expert views on both the current situation and possible future developments. Subsequent chapters consider some of the scientific and technical issues, including the evaluation of the risks which chemicals can pose to human life and the environment, and the problems relating to evaluating the risks associated with metals in the environment. Finally, the predictive methods used to model the behaviour of organic chemicals within the environment are described. Highly topical, and with authoritative contributions from international experts, this book covers both the scientific underpinning and the legislative and practical issues of this emotive subject. The detailed coverage of a topic that affects many sectors of industry and society will make it popular with a wide audience of individuals from government organisations, industry or academic research, particularly those in environmental chemistry sectors.

What happens when a chemical is released into the environment? It diffuses, disperses, adsorbs, reacts, and/or changes state. To predict and analyze this process, the mathematics of diffusion is applied to lakes, rivers, groundwater, the atmosphere, the oceans, and transport between these media. A sustainable world requires a deep understanding of the transport of chemicals through the environment and how to address and harness this process. This volume presents a succinct and in-depth introduction to this critical topic. Featuring authoritative, peer-reviewed articles from the Encyclopedia of Sustainability Science and Technology, Transport and Fate of Chemicals in the Environment represents an essential one-stop reference for an audience of researchers, undergraduate and graduate students, and industry professionals.
