Book Description
Multimedia Environmental Models: The Fugacity Approach, Third Edition, takes a broad approach of viewing chemical behavior in the total biosphere of connected biotic and abiotic compartments. Chemicals are subject to the laws of "mass balance," a constraint that provides the opportunity to establish quantitative expressions for chemical fate that are central to chemical management and regulatory legislation. This book employs both the conventional concentration-based procedures and those based on application of the more elegant and powerful concept of fugacity to characterize equilibrium, steady-state distribution, and time-dependent transport between environmental phases such as air, water, and soil. Organic chemicals are emphasized because they are more easily generalized when assessing environmental behavior. Features Illustrates professional approaches to calculating the fate of chemicals in the environment Explicitly details all worked examples in an annotated step-by-step fashion Presents real-life freely downloadable models of use to government, industry, and private consulting professionals and students alike Clarifies symbols and notation

Book Description
Pollutants released to the environment are distributed among the many environmental media such as air, water, soil, and vegetation, as the result of complex physical, chemical and biological processes. The possible environmental impact associated with chemical pollutants is related to their concentration levels and persistence in the various environmental compartments. Therefore, information regarding the migration of pollutants across environmental phase boundaries (eg., air-water, soil-water) and their accumulation in the environment is essential if we are to assess the potential environmental impact and the associated risks. In recent years it has become apparent that environmental pollution is a multimedia problem. Risk assessment and the design of appropriate pollution control measures require that we carefully consider the transport and accumulation of pollutants in the environment. We are now recognizing that the environment must be considered as a whole, and the scientific and regulatory approaches must consider the interactions of environmental media. It is also becoming apparent that single-medium approaches are partial and often counter-productive. On the other hand any multimedia program must carefully consider the rate of each environmental medium in the overall multimedia scheme.

Book Description
Bridges the gaps between regulatory, engineering, and science disciplines in order to comprehensively cover pollutant fate and transport in environmental multimedia This book presents and integrates all aspects of fate and transport: chemistry, modeling, various forms of assessment, and the environmental legal framework. It approaches each of these topics initially from a conceptual perspective before explaining the concepts in terms of the math necessary to model the problem so that students of all levels can learn and eventually contribute to the advancement of water quality science. The first third of Pollutant Fate and Transport in Environmental Multimedia is dedicated to the relevant aspects of chemistry behind the fate and transport processes. It provides relatively simple examples and problems to teach these principles. The second third of the book is based on the conceptual derivation and the use of common models to evaluate the importance of model parameters and sensitivity analysis; complex equation derivations are given in appendices. Computer exercises and available simulators teach and enforce the concepts and logic behind fate and transport modeling. The last third of the book is focused on various aspects of assessment (toxicology, risk, benefit-cost, and life cycle) and environmental legislation in the US, Europe, and China. The book closes with a set of laboratory exercises that illustrate chemical and fate and transport concepts covered in the text, with example results for most experiments. Features more introductory material on past environmental disasters and the continued need to study environmental chemistry and engineering Covers chemical toxicology with various forms of assessment, United States, European, and Chinese regulations, and advanced fate and transport modeling and regulatory implications Provides a conceptual and relatively simple mathematical approach to fate and transport modeling, yet complex derivations of most equations are given in appendices Integrates the use of numerous software packages (pC-pH, EnviroLab Simulators, Water, Wastewater, and Global Issues), and Fate©2016 Contains numerous easy-to-understand examples and problems along with answers for most end-of-the-chapter problems, and simulators for answers to fate and transport questions Includes numerous companion laboratory experiments with EnviroLab Requiring just a basic knowledge of algebra and first-year college chemistry to start, Pollutant Fate and Transport in Environmental Multimedia is an excellent textbook for upper-level undergraduate and graduate faculty and students studying environmental engineering and science.

Book Description
This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

Book Description
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.

Book Description
Many regulations issued by the U.S. Environmental Protection Agency (EPA) are based on the results of computer models. Models help EPA explain environmental phenomena in settings where direct observations are limited or unavailable, and anticipate the effects of agency policies on the environment, human health and the economy. Given the critical role played by models, the EPA asked the National Research Council to assess scientific issues related to the agency's selection and use of models in its decisions. The book recommends a series of guidelines and principles for improving agency models and decision-making processes. The centerpiece of the book's recommended vision is a life-cycle approach to model evaluation which includes peer review, corroboration of results, and other activities. This will enhance the agency's ability to respond to requirements from a 2001 law on information quality and improve policy development and implementation.
