Completely revised and updated, Multimedia Environmental Models: The Fugacity Approach, Second Edition continues to provide simple techniques for calculating how chemicals behave in the environment, where they accumulate, how long they persist, and how this leads to human exposure. The book develops, describes, and illustrates the framework and procedures for calculating the behavior of chemicals in our multimedia environment of air, water, soil, and sediments, as well as the diversity of biota that reside in these media. While other books focus on specific compartments, such as the atmosphere, or specific substances, such as PCBs, this book presents the big picture of how organic chemicals behave in the total environment. It does this by providing examples of calculation methods based on the fugacity approach and explaining how to access up-to-date property databases and estimation methods as well as computer programs, which are available from the Internet. In addition, the models are Web based, instead of on a floppy disk as in the previous edition. Building on the work developed in the First Edition, the Second Edition includes: A how-to modeling section, more worked examples and problems- most with solutions and answers Expanded treatment of structure-activity relationships and modern estimation methods More material illustrating applications to bioaccumulation is specific organisms and food webs Emphasis on current efforts to identify PBT chemicals and exposure analysis as a component of risk assessment Examples that provide each step of modeling calculations Web-based models, and references to property databases, estimation methods, and computer programs from the Internet When you need to make assessments of chemical behavior you need current, comprehensive. Multimedia Environmental Models: The Fugacity Approach provides you with not only an understanding of how the multitude of organic chemicals behave in the total environment, but also with practical examples of how this behavior can be predicted using the fugacity approach.

Um die Gefährdung der Umwelt durch Chemikalien einschätzen zu können, reicht es nicht aus, nur die Schadwirkung, d. h. den Einfluss der Chemikalie auf die Umwelt zu betrachten. Auch der Einfluss der Umwelt auf die Chemikalie spielt eine wichtige Rolle, über deren Verteilung, Verbreitung und Abbau in den verschiedenen Umweltkompartimenten. Seit etwa 30 Jahren existieren immer wieder verbesserte Modelle, die diese Umweltfaktoren abbilden und eine Vorhersage zu Dauer und Intensität der Umweltgefährdung nach Freisetzung eines Schadstoffes ermöglichen. Mit Hilfe dieser Einführung in die Grundlagen des Verhaltens von Chemikalien in der Umwelt wird der Leser in die Lage versetzt, die verfügbaren Rechenmodelle und Simulationen zum Abbau von Chemikalien in Luft, Wasser und Boden sinnvoll einzusetzen und deren Ergebnisse fachgerecht zu interpretieren. Das Buch besteht aus vier Teilen. Der erste Teil dient als Einleitung in die Thematik, der zweite befasst sich mit der Verbreitung und Verteilung von Chemikalien in Luft, Wasser und Boden. Im dritten Teil wird der abiotische und biotische Abbau der Chemikalien betrachtet. Im vierten Teil schließlich werden die verschiedenen Verteilungs- und Abbauwege zu einfachen bis komplexen Rechenmodellen zusammengefügt, und die wichtigsten, von nationalen und internationalen Organisationen verwendeten Modelle werden eingehend anhand von Beispielen erläutert.

The word 'sustainability' is frequently misunderstood because there are numerous definitions of sustainability and not even two definitions have converging meanings. Instead of achieving 'sustainability', some of the sustainable development projects aggravate ecological and other problems, as painfully evidenced in numerous experimental projects. This book attempts to improve our understanding of what it means to be sustainable by exploring several different sustainability projects and techniques.

Ecotoxicology Modeling is a comprehensive and well-documented text providing a collection of computational methods to the ecotoxicologists primarily interested in the study of the adverse effects of chemicals, their mechanisms of action and/or their environmental fate and behavior. Avoiding mathematical jargon, the book presents numerous case studies to enable the reader to understand the interest but also the limitations of linear and nonlinear models in ecotoxicology. Written by an international team of scientists, Ecotoxicology Modeling is of primary interest to those whose research or professional activity is directly concerned with the development and application of models in ecotoxicology. It is also intended to provide the graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches used in environmental sciences.

Revised, updated, and rewritten where necessary, but keeping the clear writing and organizational style that made previous editions so popular, Elements of Environmental Engineering: Thermodynamics and Kinetics, Third Edition contains new problems and new examples that better illustrate theory. The new edition contains examples with practical flavor such as global warming, ozone layer depletion, nanotechnology, green chemistry, and green engineering. With detailed theoretical discussion and principles illuminated by numerical examples, this book fills the gaps in coverage of the principles and applications of kinetics and thermodynamics in environmental engineering and science. New topics covered include: Green Chemistry and Engineering Biological Processes Life Cycle Analysis Global Climate Change The author discusses the applications of thermodynamics and kinetics and delineates the distribution of pollutants and the interrelationships between them. His demonstration of the theoretical foundations of chemical property estimations gives students an in depth understanding of the limitations of thermodynamics and kinetics as applied to environmental fate and transport modeling and separation processes for waste treatment. His treatment of the material underlines the multidisciplinary nature of environmental engineering. This book is unusual in environmental engineering since it deals exclusively with the applications of chemical thermodynamics and kinetics in environmental processes. The book’s multimedia approach to fate and transport modeling and in pollution control design options provides a science and engineering treatment of environmental problems.

Rational Environmental Management of Agrochemicals will impact the agrochemical industry with its comprehensive survey of rational principles that should be used to select and manage the best agrochemicals while also encouraging the registration of new chemicals with reduced risk of every kind. This book will present papers from one of the most well-attended symposia presented at the PacifiChem Conference with a range of 30 papers presenting the most recent advances in risk assessment and management of organic agrochemicals as it relates to insecticides, herbicides and pharmaceuticals, and the development of rational methods aimed at reducing their overall impacts on trade, human, and environmental health. The concept of Rational Methods is organized under three key themes: Environmental fate and risk assessment, monitoring, and risk management and remediation. This book will contribute nicely to the series of Agrochemical Division sponsored symposium books published in recent years.

Over the past decade ecotoxicology has emerged as a distinct subject of interdisciplinary character. Courses in ecotoxicology reflect this and are taught by specialists in chemistry and biochemistry through to population genetics and ecology. As the first textbook to incorporate all relevant aspects of chemistry, biochemistry, toxicology, physiology, population ecology and population genetics, the first edition of this book proved to be well received across several industries. Featuring fully revised text and new illustrations, Principles of Ecotoxicology identifies the major classes of organic and inorganic pollutants, their properties, release and environmental fate, and transport in air, water and along food chains, before considering the effects that they might have upon individual organisms and ultimately whole ecosystems. This timely second edition of Principles of Ecotoxicology incorporates data collected since the first edition on subjects of current research and media interest such as organochloride pesticides, endocrine disruptors, aquatic toxicity, industrial waste and ecotoxicity testing.

Offshore oil and gas drilling operations take place in some of the world's most biologically productive oceanic waters. An ongoing concern related to the development of this industry is that exposure to contaminants from waste discharges may cause ill effects on organisms and their habitat. Environmental Effects Monitoring (EEM) programs are undertaken to verify environmental impact assessment predictions, to detect any unforeseen effects, and to help identify cause-effect relationships. EEM has been carried out worldwide for many offshore developments, and much has been learned about the fate of drilling and production contaminants and their biological effects. EEM programs have rapidly evolved in response to new knowledge on the transport, fate, and effects of potential contaminants; changes in regulatory requirements; and improved impact assessment technologies and statistical approaches for data interpretation. In May 2003, an international group of scientists, environmental managers, and industry representatives shared their expertise and new knowledge at the Offshore Oil and Gas Environmental Effects Monitoring Workshop. The participants reviewed the status of current offshore oil and gas EEM programs and identified future research needs to advance our understanding of the impacts of the offshore oil and gas industry. This book represents a selected number of peer-reviewed papers from workshop participants, covering a range of topics including regional experience from past and ongoing EEM programs; environmental management issues such as risk assessment and decision-making processes; the development of predictive risk assessment models; and new approaches and technologies formonitoring potential alterations in benthic, pelagic, and tropospheric ecosystem components. This book will be of use to scientists, environmental managers, regulators, and industry representatives, as well as members of the general public wishing to improve their understanding on the application of offshore oil and gas EEM programs for the protection of our ocean environment and its resources.
