This is a textbook for courses and independent study in environmental and chemical engineering, as well as in many other disciplines concerned with transport and diffusion of all manner of chemicals. Estimating the transport and fate of chemicals released into the environment is an interesting and challenging task. The global environment is large, on the chemical transport and fate scale. This text applies the mathematics of diffusion, turbulent diffusion and dispersion to the atmosphere, lakes, rivers, groundwater and the ocean, as well as transport between these media. The required theory is explained as a solution technique to solve the case studies and example problems. A large portion of the book is dedicated to examples and case studies, from which the important principles are derived.

This book offers a detailed yet accessible introduction to transport phenomena. It begins by explaining the underlying principles and mechanisms that govern mass transport, and continues by tackling practical problems spanning all subdisciplines of environmental science and chemical engineering. Assuming some knowledge of ordinary differential equations and a familiarity with basic fluid mechanics applications, this classroom-tested text addresses mass conservation and macroscopic mass balances, placing a special emphasis on applications to environmental processes and presenting a mathematical framework for formulating and solving transport phenomena problems.

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.

The third edition of Chemical Fate and Transport in the Environment—winner of a 2015 Textbook Excellence Award (Texty) from The Text and Academic Authors Association—explains the fundamental principles of mass transport, chemical partitioning, and chemical/biological transformations in surface waters, in soil and groundwater, and in air. Each of these three major environmental media is introduced by descriptive overviews, followed by a presentation of the controlling physical, chemical, and biological processes. The text emphasizes intuitively based mathematical models for chemical transport and transformations in the environment, and serves both as a textbook for senior undergraduate and graduate courses in environmental science and engineering, and as a standard reference for environmental practitioners. Winner of a 2015 Texty Award from the Text and Academic Authors Association Includes many worked examples as well as extensive exercises at the end of each chapter Illustrates the interconnections and similarities among environmental media through its coverage of surface waters, the subsurface, and the atmosphere Written and organized concisely to map to a single-semester course Discusses and builds upon fundamental concepts, ensuring that the material is accessible to readers who do not have an extensive background in environmental science

A comprehensive account of the state of the science of environmental mass transportEdited by Louis J. Thibodeaux and Donald Mackay, renowned experts in this field, the Handbook of Chemical Mass Transport in the Environment covers those processes which are critically important for assessing chemical fate, exposure, and risk. In a comprehensive and a

A highly-accessible introduction to mass transfer problems in environmental engineering and science. Chemical transport processes in environmental systems are exceptionally complex and notoriously difficult to model. Unlike equations derived for homogenous, well-defined environments in chemical production, for example, equations derived for environmental systems rely upon calculations made for highly heterogeneous, often poorly defined environments consisting of a great many phases and chemicals. Unfortunately, texts on chemical transport usually focus on problems related to chemical process engineering, making it exceedingly difficult for environmental engineers to model processes in natural and engineered systems. This book provides practicing engineers and graduate students with a clear, comprehensive introduction to transport processes in environmental systems. Structured to suit a one-semester, introductory course on the subject, it begins with the basics of molecular diffusion and chemical partitioning and then progresses to more advanced topics including dispersion, particle transport, fractals, and biofilms. Throughout, the author places an equal emphasis on both engineered and natural systems. Each chapter draws on realistic examples and problems to reinforce important concepts. Environmental Transport Processes is an ideal first textbook for environmental engineering students who have never studied mass transport, as well as undergraduate and graduate chemical engineering students with little or no experience in environmental topics. It is also a valuable working resource for professionals in those fields, and all researchers interested in transport processes.
