DOWNLOAD EBOOKMultimedia 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
Pollutants in a Multimedia Environment

DOWNLOAD EBOOKPollutants 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.

DOWNLOAD EBOOKWhat 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.

DOWNLOAD EBOOKBridges 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.

DOWNLOAD EBOOKWater Environment Modeling covers the formulations and applications of mathematical models that simulate water flow and chemical transport in rivers, lakes, groundwater, estuaries, coastal, and ocean waters. These models are used to evaluate the response of water environment to human interventions and serve as useful analytical tools for water pollution control and resource management. Simple and comprehensive modeling techniques and their practical applications are presented with examples and exercises, most of which are derived from actual case studies. In general, simple models can be solved analytically and comprehensive models require numerical solutions. While simple models are usually adopted for preliminary assessment of a particular water environment, comprehensive models are used to provide detailed spatial and temporal variations of pollutants in complex environments. The system-based models in the forms of integral equations are introduced as an alternative modeling approach. This textbook is ideal for advanced undergraduate students and graduate students in civil and environmental engineering and related academic fields. It is also suitable as a reference book for practicing engineers and scientists. Authors: Clark C.K. Liu is Emeritus Professor of the Department of Civil and Environmental Engineering at University of Hawaii and former Environmental Engineering Director of US National Science Foundation. Pengzhi Lin is Professor of State Key Laboratory of Hydraulics and Mountain River Engineering at Sichuan University. He is the author of Numerical Modeling of Water Waves (CRC Press, 2008).
