Chemical Fate and Transport in the Environment is a textbook for upper division undergraduate and graduate students studying environmental sciences in engineering, hydrology, chemistry, and other related disciplines. It covers the fundamental principles of mass transport and chemical partitioning, and the transformation of substances in surface water, in groundwater or subsurface environments, and in the atmosphere. Three major areas-surface water, ground water, and air-are covered, with descriptive overviews for each area. Each major section begins by describing environment: its controlling physical, chemical, and biological processes. The book also contains examples of common environmental problems and includes problem sets at the end of each chapter. Text that has been developed from a course taught at MIT Broad-based coverage of the environmental sciences A more rigorous treatment of transport than found in other texts Exercise sets at the end of each chapter Examples of current environmental problems fully integrated into the text Ample references for access to the primary literature Numerous illustrations throughout

A uniquely accessible text on environmental modeling designed for both students and industry personnel Pollutant fate and modeling are becoming increasingly important in both regulatory and scientific areas. However,the complexity of the software and models often act as an inhibitor to the advancement of water quality science. A Basic Introduction to Pollutant Fate and Transport fills the need for a basic instructional tool for students and environmental professionals who lack the rigorous mathematical background necessary to derive the governing fate and transport equations. Taking a refreshingly simple approach to the subject that requires only a basic knowledge of algebra and first-year college chemistry, the book presents and integrates all of the aspects of fate and transport, including chemistry, modeling, risk assessment, and relevant environmental legislation; approaching each topic first conceptually before introducing the math necessary to model it. The first half of the book is dedicated to the chemistry and physics behind the fate and transport models, while the second half teaches and reinforces the logical concepts underlying fate and transport modeling. This better prepares students for support jobs in the environmental arena surrounding chemical industry and Superfund sites. Contributing to the book's ease of use are: An extremely user-friendly software program, Fate, which uses basic models to predict the fate and transport of pollutants in lakes, rivers, groundwater, and atmospheric systems The use of "canned" models to evaluate the importance of model parameters and sensitivity analysis A wealth of easy-to-understand examples and problems A chapter on environmental legislation in the United States and Europe A set of lab exercises, as well as a downloadable set of teaching aids A much-needed basic text for contemporary hydrology or environmental chemistry courses and support courses forthe environmental industry, this is a valuable desk reference for educators and industry professionals.

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.

"This updated and expanded third edition of Chemical Fate and Transport in the Environment covers the fundamental principles of mass transport, chemical partitioning, and chemical/biological transformation of pollutants and naturally occuring chemicals in surface waters, in soil and groundwater, and in the atmosphere. Each of these three major environmental media is introduced by descriptive overviews, followed by presentation of the governing physical, chemical, and biological processes. The text emphasizes intuitively based mathematical models for transport, equilibria, and transformations of chemicals in the environment. It serves as a textbook for graduate and senior undergraduate courses in environmental science and engineering, provides necessary scientific knowledge for students of public health and environmental policy, and is an essential reference for environmental practitioners"--Page 4 of cover.

Fate and Transport provides the equations and background information you need to predict the fate and transport of chemicals in air, water, soil, flora, and fauna, and to prevent your exposure to toxic chemicals. Featuring 22 new mathematical calculations for predicting the fate and transport of 100 non-pesticide organic compounds, this Third Edition provides you with easy-to-read explanations of how chemicals travel through the environmental compartments, how they break down, and how key physical and chemical properties of chemicals (including water solubility, volatility, and soil sorbtion or adsorption) affect fate and transport. The book also addresses methods for predicting pesticide and fish hazards, offer complete samples of calculations and exposure analyses, includes date for 203 commonly encountered chemical substances, and explains hazard prediction based on chemical structure.

During the last four decades, tremendous advances have been made towards the understanding of transport characteristics of contaminants in soils, solutes, and tracers in geological media. Transport & Fate of Chemicals in Soils: Principles & Applications offers a comprehensive treatment of the subject complete with supporting examples of mathematical models that describe contaminants reactivity and transport in soils and aquifers. This approach makes it a practical guide for designing experiments and collecting data that focus on characterizing retention as well as release kinetic reactions in soils and contaminant transport experiments in the laboratory, greenhouse), and in the field. The book provides the basic framework of the principals governing the sorption and transport of chemicalsin soils. It focuses on physical processes such as fractured media, multiregion, multiple porosities, and heterogeneity and effect of scale as well as chemical processes such as nonlinear kinetics, release and desorption hysteresis, multisite and multireaction reactions, and competitive-type reactions. The coverage also includes details of sorption behavior of chemicals with soil matrix surfaces as well the integration of sorption characteristics with mechanisms that govern solute transport in soils. The discussions of applications of the principles of sorption and transport are not restricted to contaminants, but also include nitrogen, phosphorus, and trace elements including essential micronutrients, heavy metals, military explosives, pesticides, and radionuclides. Written in a very clear and easy-to-follow language by a pioneer in soil science, this book details the basic framework of the physical and chemical processes governing the transport of contaminants, trace elements, and heavy metals in soils. Highly practical, it includes laboratory methods, examples, and empirical formulations. The approach taken by the author gives you not only the fundamentals of understanding of reactive chemicals retention and their transport in soils and aquifers, but practical guidance you can put to immediate use in designing experiments and collecting data.
