The zone where land and sea meet is composed of a variety of complex environments. The coastal areas of the world contain a large percentage of its population and are therefore of extreme economic importance. Industrial, residential, and recreational developments, as well as large urban complexes, occupy much of the coastal margin of most highly developed countries. Undoubtedly future expansion in many undeveloped maritime countries will also be concentrated on coastal areas. Accompanying our occupation of coasts in this age of technology is a dependence on coastal environments for transportation, food, water, defense, and recreation. In order to utilize the coastal zone to its capacity, and yet not plunder its resources, we must have extensive knowledge of the complex environments contained along the coasts. The many environments within the coastal zone include bays, estuaries, deltas, marshes, dunes, and beaches. A tremendously broad range of conditions is represented by these environments. Salinity may range from essentially fresh water in estuaries, such as along the east coast of the United States, to extreme hypersaline lagoons, such as Laguna Madre in Texas. Coastal environments may be in excess of a hundred meters deep (fjords) or may extend several meters above sea level in the form of dunes. Some coastal environments are well protected and are not subjected to high physical energy except for occasional storms, whereas beaches and tidal inlets are continuously modified by waves and currents.

Volume 9 of Chemical Mutagens consists mainly of chapters discussing the development and validation of short-term assays to detect the mutagenic effects of environmental chemicals. These chapters include an assay with the grasshopper neuroblast, a comparison of mutagenic responses of human lung-derived and skin-derived diploid fibroblasts, a forward-mutation assay in Salmonella, a multigene sporulation test in Bacillus subtilis, a specific locus assay in mouse lymphoma cells, a study of the induction of bacteriophage lambda, and the granuloma pouch assay. In addition, there are two chapters on the identification of mutagens in cooked food and in human feces.

This book introduces expert systems for problem solving in urban planning and describes the way in which heuristic knowledge and rules of thumb of expert planners can be represented through computer programs. The book presents practical applications of expert systems for solving many important urban planning problems, particularly those issues that many practicing planners face in their daily operations. Problems and issues discussed are grouped in the following categories: - Land Use Planning - Transportation Planning - Site Selection and Analysis - Environmental Planning - Conflict Mediation and Legal Disputes - Future Developments and Directions Expert Systems: Applications to Urban Planning will benefit both urban planners who wish to learn how this new technology might be applied to their daily work as well as researchers in expert systems seeking new ideas for systems design.

The pilot study on estuarine management was initiated by the NATO Committee on the Challenges of Modem Society (CCMS). The objective of this project was to make a comparison of several estuarine management strategies and to formulate a set of recommen dations and planning guidelines to restore polluted estuaries, to prevent further estuarine deterioration, and to manage conflicting demands stemming from human activities. The first results of this NATO-CCMS project were reported in 1982, describing six estuaries and their management approaches. In 1985 CCMS decided a subsequent research project should be performed to achieve the original objectives. This second research project was basically done by way of a comprehensive questionnaire that was sent to authorities of estuarine areas all over the world. Eleven questionnaires have been received. In some instances, the questionnaires were not fully completed for several reasons. Especially, data on water quality was lacking. As a result, less attention will be paid to related aspects as originally intended. This study shows that knowledge of the number of functions and conflicts of estuaries may provide relevant information concerning the severity of the problems as well as the propensity towards planning of water systems."

Unlike existing books of nuclear reactor physics, nuclear engineering and nuclear chemical engineering this book covers a complete description and evaluation of nuclear fission power generation. It covers the whole nuclear fuel cycle, from the extraction of natural uranium from ore mines, uranium conversion and enrichment up to the fabrication of fuel elements for the cores of various types of fission reactors. This is followed by the description of the different fuel cycle options and the final storage in nuclear waste repositories. In addition the release of radioactivity under normal and possible accidental conditions is given for all parts of the nuclear fuel cycle and especially for the different fission reactor types.

Solid waste management is currently a major issue worldwide with numerous areas reaching critical levels. Many developing countries and countries in transition still miss basic waste management infrastructure and awareness. It is here that many of the solid waste management problems and challenges are currently being faced. As such, waste-to-energy (WTE) consists of a proven and continuously developing spectrum and range of technologies in a number of (mostly) developed countries. However, it's integration in developing countries and systems in transition is often faced with scepticism and a complex set of barriers which are quite unique and differ greatly from those where WTE has been validated and applied over the years. Waste-to-Energy: Opportunities and Challenges for Developing and Transition Economies will address this issue both theoretically and using concrete examples, including: * contributions from numerous scholars and practitioners in the field, * useful lessons and rules of thumb, * both successful and failed cases, and * real-life examples and developments. Waste-to-Energy approaches this dynamic aspect of environmental engineering and management in a methodical and detailed manner making it an important resource for SWM planners and facility operators as well as undergraduate and post graduate students and researchers.

As the availability of fossils fuels becomes more limited, the negative impact of their consumption becomes an increasingly relevant factor in our choices with regards to primary energy sources. The exponentially increasing demand for energy is reflected in the mass generation of by-products and waste flows which characterize current society's development and use of fossil sources. The potential for recoverable material and energy in these ever-increasing refuse flows is huge, even after the separation of hazardous constituent elements, allowing safe and sustainable further exploitation of an otherwise 'wasted' resource. Fuel Cells in the Waste-to-Energy Chain explores the concept of waste-to-energy through a 5 step process which reflects the stages during the transformation of refuse flows to a valuable commodity such as clean energy. By providing selected, integrated alternatives to the current centralized, wasteful, fossil-fuel based infrastructure, Fuel Cells in the Waste-to-Energy Chain explores how the concept of waste-to-energy can be constructed and developed into a realistic solution. The entire spectrum of current and future energy problems is illuminated through the explanation of the operational, integration and marketing implications of high efficiency technological solutions using the real context of developed regions such as Europe. Up-to-date reviews are provided on the status of technology and demonstration, implementation and marketing perspectives. The detailed technological information and insight gathered from over twenty years of experience in the field makes Fuel Cells in the Waste-to-Energy Chain a valuable resource for all engineers and researchers in the fields of energy supply systems and waste conversion, as well as providing a key reference for discussions by policy makers, marketing experts and industry developers working in energy supply and waste management.

Chemical additives are used to enhance the properties of many industrial products. Since their release into the environment is a potential risk for man and nature, their fate and behavior were investigated in the framework of the European Union-funded project RISKCYCLE. The results are presented in two volumes, "Global Risk-Based Management of Chemical Additives I: Production, Usage and Environmental Occurrence" and "Global Risk-Based Management of Chemical Additives II: Risk-Based Assessment and Management Strategies." This book is the first of the two volumes and contains two main parts. The chapters of the first part provide a thorough review of the chemical additives used in the textile, plastics, lubricants, paper, leather and electronics industries, and describe the effect of each additive on the properties of the product. In the second part international case studies on the global trade of these chemicals and their impact on human health and the environment are presented.

This volume is an invaluable source of information for scientists and governmental agencies dealing with the risk assessment of chemicals on a global scale.

Environmental chemistry is a fast developing science aimed at deciphering fundamental mechanisms ruling the behaviour of pollutants in ecosystems. Applying this knowledge to current environmental issues leads to the remediation of environmental media, and to new, low energy, low emission, sustainable processes. Nanotechnology applications for alternative energies such as solar power, fuel cells, hydrogen and lithium batteries are reviewed in the first section. Recent investigations on carbon nanotubes, nanocatalysts and cyclodextrins disclose unprecedented techniques to monitor and clean pollutants such as greenhouse gases, heavy metals, pesticides, pathogens occurring in water, air and soil. The second section reviews the risks for human health of critical pollutants such as endocrine disruptors, dioxins and heavy metals contaminating seafood and sediments. An exhaustive review of DDT isomers reveals unexpected mechanisms of DDT transfer to fishes. A chapter on pollutant geochronology using river sedimentary archives provides novel insights on pollution history since the beginning of the anthropocene.

This book will be a valuable source of information for engineers and students developing novel applied techniques to monitor and clean pollutants in air, wastewater, soils and sediments.

Water - and its governance - is becoming a global concern partly because it is turning into a goods in short supply, with devastating effects on literally billions of people, but also because it is the "carrier" ofglobal warming; whether through irregular weather patterns or through flooding, water is how global warming will be 'felt'. The lion's share of the globally available fresh water resources is to be found in transboundary systems. In spite of its significance, the generated knowledge on how to deal with transboundary waters is weak and leaves policy makers with seemingly unavoidable, trade-off dilemmas and prioritizations, often with detrimental effects. In order to disentangle this predicament this volume works with one case: the Lower Mekong Basin and covers state-of-the-art academic and practitioners' knowledge and hence appeals to a wide audience. The topic this volume addresses is situated in the nexus ofan IR- (International Relations) approach focussing on transboundary politics and its inclination to remain within the sphere of state sovereignty and national interest on the one hand, and Development studies, with its imperatives on participation, planning, and intervention, on the other.The dilemma, we argue, of better understanding transboundary water management lies in how to understand how these two rationalities can be simultaneously nurtured.
"Audience: "This book will be relevant to scholars, as it provides cutting-edge research, and students, since it covers the primary debates in the field, interested in resource management, regional politics, and development issues in the area. It also addresses the global debate on transboundary water management and presents an in-depth case of one of the globally most sophisticated attempts at pursuing sustainable river basin management. Finally, practitioners and policymakers would benefit greatly because all contributions have explicit policy relevance, launching suggestion on improvements in water management.

Environmental chemistry is a fast developing science aimed at deciphering fundamental mechanisms ruling the behaviour of pollutants in ecosystems. Applying this knowledge to current environmental issues leads to the remediation of environmental media, and to new, low energy, low emission, sustainable processes. Chapters review analysis and remediation of pollutants such as greenhouse gases, chiral pharmaceuticals, dyes, chlorinated organics, arsenic, toxic metals and pathogen in air, water, plant and soil. Several highlights include the overlooked impact of air pollutants from buildings for health risk, innovative remediation techniques such as bioreactors for gas treatment, electrochemical cleaning of pharmaceuticals, sequestration on Fe-Mn nodules, phytoremediation and photocatalytical inactivation of microbial pathogens.

This book will be a valuable source of information for engineers and students developing novel applied techniques to monitor and clean pollutants in air, wastewater, soils and sediments.

In the field of biosensors the previous focus has been almost entirely on medical diagnostics. Here it is discussed in relation to bioremediation. The application of new biosensing techniques to environmental monitoring promises to be a more economical approach to monitoring both soil consortia and levels of pollutants. Significantly, functional biosensors can determine such parameters asHow clean is clean?' This new edition is targeted specifically at graduate students and environmental professionals.

The first Symposium on Recent Advances in Problems of Flow and Transport in Porous Media was held in Marrakech in June '96 and has provided a focus for the utilization of computer methods for solving the many complex problems encountered in the field of solute transport in porous media. This symposium has been successful in bringing together scientists, physicists, hydrogeologists, researchers in soil and fluid mechanics and engineers involved in this multidisciplinary subject. It is clear that the utilization of computer-based models in this domain is still rapidly expanding and that new and novel solutions are being developed. The contributed papers which form this book reflect the recent advances, in particular with respect to new methods, inverse problems, reactive transport, unsaturated media and upscaling. These have been subdivided into the following sections: I. Numerical methods II. Mass transport and heat transfer III. Comparison with experimentation and simulation of real cases This book contains reviewed articles of the top presentations held during the International Symposium on Computer Methods in Porous Media Engineering which took place in Giens (France) in October 1998. All of the presentations and the optimism shown during the meeting provided further evidence that computer modeling is making remarkable progress and is indeed becoming an essential toolkit in the field of porous media and solute transport. I believe that the content of this book provides evidence of this and furthermore gives a comprehensive review of the theoretical developments and applications.

The diverse nature of environmental problems mankind has encountered within the last decade has developed a new understanding of the nature of environmental processes. Currently, the environment is considered as a continuum of air, soil and water as the vital components for sustaining life on earth. The interactive nature of these components requires that the environment is managed and protected as a cohesive whole. This can only be accomplished through an integrated approach to environmental management. Besides the concept of environmental continuum, prospects for sustainable development of natural resources and the recent recognition of global climate change impacts have also necessitated such an integrated approach to environmental management. Two basic tools for integrated management of the environment are modeling and environmental data. Both tools were available and valid in the past; however, the recent requirements for integrated environmental management have also led to a significant evolution of both modeling procedures and data management systems.

Polymers, main components of plastics and rubbers, are being discarded in increasing quantities. But this waste can also be considered as plastic gold'. Public concern, coupled with the inherent value of the material, means that recycling is imperative. The present book presents a survey of current knowledge in the form of case studies, including current legal and educational issues. Topics covered also include regulation and practice in NATO countries, the economics of recycling, the reprocessing of single polymers and mixtures, and future prospects and strategies. Audience: Vital reading for all polymer scientists, technicians and engineers.

It is generally acknowledged today that the most effective strategy for toxic and hazardous waste management is: reduction, reuse and recycle. However, to date most of the activity has been in treatment technologies. This book focuses on recent technological issues commercially available or in various stages of implementation. Developments in the U.S. and Europe in the area of waste management policy and regulation are also examined since management and remediation have usually been conducted in response to regulatory requirements. This book serves as a state of the art resource on technologies and methodologies for the environmental protection manager involved in decisions concerning the management of toxic and hazardous waste.

At the dawn of the 21st century, biotechnology is emerging as a key enabling technology for sustainable environmental protection and stewardship. Biotechnology for the Environment: Wastewater Treatment and Modeling, Waste Gas Handling illustrates the current technological applications of microorganisms in wastewater treatment and in the control of waste gas emissions. In the first section of the book special emphasis is placed on the use of rigorous mathematical and conceptual models for an in-depth understanding of the complex biology and engineering aspects underlying the operation of modern wastewater treatment installations. The second part addresses waste gas biofiltration, an expanding biotechnological application of microbial metabolism for air quality assurance through processes ranging from the abatement of hazardous volatile pollutants to the elimination of nuisance odors. It will be a valuable reference source for environmental scientists, engineers and decision makers involved in the development, evaluation or implementation of biological treatment systems.

Both the beauty and interest of fractures and fracture networks are easy to grasp, since they are abundant in nature. An example is the road from Digne to Nice in the south of France, with an impressive number and variety of such structures: the road for the most part, goes through narrow valleys with fast running streams penetrating the rock faces; erosion is favored by the Mediterranean climate, so that rocks are barely covered by meager vegetation. In this inhospitable and sterile landscape, the visitor can im mediately discover innumerable fractures in great masses which have been distorted by slow, yet powerful movements. This phenomenon can be seen for about 100 kilometers; all kinds of shapes and combinations are repre sented and can be observed either in the mountain itself or in the man-made cliffs and excavations, resulting from improvements made to the road. In the same region, close to the Turini Pass, a real large scale hydrody namic experiment is taking place -a source which is situated on the flank on the mountain, has been equiped with a tap; if the tap is open, water flows through the tap only, but when it is closed, then the side of the mountain releases water in a matter of seconds. Other outlets are also influenced by this tap, such as a water basin situated a few hundred meters away."

Foreword Over the past decades, Piero Risoluti has built up an intimate knowl edge of the nuclear industry - in particular of nuclear waste man agement. In this book, his scientific understanding is apparent - for example in his comprehensive but readily understandable descrip tions of waste conditioning and disposal. Moreover, he has also been directly involved in the wider societal and political debates in the nuclear area - especially in his Italian homeland. What shines through in these pages is.his frustration at the lack of progress in im plementing disposal concepts that are judged by many to be very safe and his unfaltering drive to improve this situation. To provoke debate, the book is very deliberately written in a po larising, black and white style that can easily be labelled as "politi cally incorrect" - a characterisation that Piero will probably agree with and be amused by. Criticism is directed equally at "loud mouthed and incompetent anti-nuclear environmentalists," the "nu clear Byzantium" of the international nuclear establishment, the "in tellectual narcissism" of those nuclear experts that dare to admit the importance of societal issues, and the tendency of politicians to "in definite procrastination." These are not words chosen to avoid open confrontation of opposing views."

Newly developed and innovative methods are mentioned and outlined so that the book can be used as a source of information for scientists and professionals specialised in the treatment of soils as well as for students in courses of environmental studies. The book offers a short, compressed overview of the important features of this subject and can be used as a reference book of the state of the art. The appendix offers the interested reader a detailed survey of materials, test methods and apparatuses as well as a description of analytical directions and processes.

This book is about the legal, economical, and practical assessment and management of risky activities arising from routine, catastrophic environmental and occupational exposures to hazardous agents. It includes a discussion of aspects of US and European Union law concerning risky activities, and then develops the economic analyses that are relevant to implementing choices within a supply and demand framework. The book also discusses exposure-response and time-series models used in assessing air and water pollution, as well as probabilistic cancer models, including toxicological compartmental, pharmaco-kinetic models and epidemiological relative risks and odds ratios-based models. Statistical methods to measure agreement, correlation and discordance are also developed. The methods and criteria of decision-analysis, including several measures of value of information (VOI) conclude the expositions. This book is an excellent text for students studying risk assessment and management.
