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.

Environmental Modeling, Second Edition combines engineering transport fundamentals and equilibrium aquatic chemistry. It brings a uniquely contemporary perspective to the assessment of environmental quality. In addressing key questions about fate, transport, and long-term effects of chemical pollutants in the environment, this inherently practical book gives readers the important tools they need to develop and solve their own mathematical models. The book 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.

Increasingly used to represent climatic, biogeochemical, and ecological systems, computer modeling has become an important tool that should be in every environmental professional’s toolbox. Environmental Modeling: A Practical Introduction is just what it purports to be, a practical introduction to the various methods, techniques, and skills required for computerized environmental modeling. Exploring the broad arena of environmental modeling, the book demonstrates how to represent an environmental problem in conceptual terms, formalize the conceptual model using mathematical expressions, convert the mathematical model into a program that can be run on a desktop or laptop computer, and examine the results produced by the computational model. Equally important, the book imparts skills that allow you to develop, implement, and experiment with a range of computerized environmental models. The emphasis is on active engagement in the modeling process rather than on passive learning about a suite of well-established models. The author takes a practical approach throughout, one that does not get bogged down in the details of the underlying mathematics and that encourages learning through “hands on” experimentation. He provides a set of software tools and data sets that you can use to work through the various examples and exercises presented in each chapter, as well as presentational material and handouts for course tutors. Comprehensive and up-to-date, the book discusses how computational models can be used to represent environmental systems and illustrates how such models improve understanding of the ways in which environmental systems function.
