What happens to a chemical once it enters the natural environment? How do its physical and chemical properties influence its transport, persistence, and partitioning in the biosphere? How do natural forces influence its distribution? How are the answers to these questions useful in making toxicological and epidemiological forecasts? Environmental Chemodynamics, Second Edition introduces readers to the concepts, tools, and techniques currently used to answer these and other critical questions about the fate and transport of chemicals in the natural environment. Like its critically acclaimed predecessor, its main focus is on the mechanisms and rates of movement of chemicals across the air/soil, soil/water, and water/air interfaces, and on how natural processes work to mobilize chemicals near and across interfaces––information vital to performing human and ecological risk assessments. Also consistent with the first edition, Environmental Chemodynamics, Second Edition is organized to accommodate readers of every level of experience. The first section is devoted to theoretical underpinnings and includes discussions of mass balance, thermodynamics, transport science concepts, and more. The second section concentrates on practical aspects, including the movement between bed–sediment and water, movement between soil and air, and intraphase chemical behavior. This revised and updated edition of Louis J. Thibodeaux′s 1979 classic features new or expanded coverage of: ∗ Equilibrium models for environmental compartments ∗ Dry deposition of particles and vapors onto water and soil surfaces ∗ Chemical profiles in rivers and estuaries, particles and porous media ∗ Fate and transport in the atmospheric boundary layer and within subterranean media ∗ Chemical exchange between water column and bed–sediment ∗ Intraphase chemical transport and fate This Second Edition of Environmental Chemodynamics also includes twice as many references and 50% more exercises and practice problems.

A comprehensive, thoroughly modern approach to environmental quality assessment The only textbook to combine engineering transport fundamentals and equilibrium aquatic chemistry, Environmental Modeling brings a uniquely contemporary perspective to the assessment of environmental quality. Addressing key questions about fate, transport, and long-term effects of chemical pollutants in the environment, this inherently practical text gives readers the important tools they need to develop and solve their own mathematical models. Contains detailed examples from a wide range of crucial water quality areas-conventional pollutants in rivers, eutrophication of lakes, and toxic organic chemicals and heavy metals in both surface and groundwaters Examines current global issues, including atmospheric deposition, hazardous wastes, soil pollution, global change, and more Features over 200 high-quality illustrations, plus skill-building problems in every chapter Fresh in approach and broad in scope, Environmental Modeling is must reading for today's graduate and advanced undergraduate students in environmental sciences and engineering-a rich, invaluable, and superlative new resource.

Reflecting the best current thinking and techniques in the field, here is a multi-disciplinary analysis of the dynamics and mechanisms of aquatic systems, using lakes as a point of departure. The contributors, all of whom are recognized world authorities, treat physical, chemical and biological processes such as transport and distribution of chemicals, aquatic surface chemistry, and geobiological cycles of trace elements, which can be applied to all-natural water systems--oceans, rivers and estuaries. Stresses explanation and dynamics rather than documentation.
