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.

The aim of this book is to help create new feedstuffs for poultry and farm animals from the agro-industry and to mobilize the neglected waste as a feedstuff to lower the price of animal products such as eggs, white and red meat, milk, etc. Furthermore, this book aims to contribute to the campaign against hunger in the developing world and to reduce the competition between animals and human beings for cereals and pulses. Accordingly the global pollution problem will be reduced. This book will be of great interest to all those involved in the animal feed and poultry industries, in agricultural universities, and in research establishments where animal nutrition is studied and taught.

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."

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.

Composting is increasingly used as a recycling technology for organic wastes. Knowledge on the composition and activities of compost microbial communities has so far been based on traditional methods. New molecular and physiological tools now offer new insights into the "black box" of decaying material. An unforeseen diversity of microorganisms are involved in composting, opening up an enormous potential for future process and product improvements. In this book, the views of scientists, engineers and end-users on compost production, process optimisation, standardisation and product application are presented.

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.

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."

Arid and semi-arid regions can be defined as environments in which water is the limit ing factor for bio-systems. This means that survival of life in these regions involves a constant struggle to obtain this limited commodity and draw the maximum benefit out of it. However, despite the difficulties for plants, animals, and man to live in, these regions, they are being utilized more and more because of the pressure of world population growth. This is expressed in the expansion of agricultural activities in desert lands as well as by the formation and rapid growth of urban and industrial centers. These trends result in a growing demand for water on the one hand, and the disposal of vast amounts of waste water, as well as other types of refuse, on the other. Meeting the first demand, namely, supplying water to the agricultural communities and urban centers, involves, in many instances, the over-exploitation and misuse of nat ural water resources. The surplus of waste water, sometimes highly loaded with toxic compounds, is likely to cause irreversible damage to the environment. The geoscientists and engineers face a challenge on two conflicting fronts. Success on one front, namely, in answering the full demand for water, may lead to an increase in the pollution of the environment by waste water."

In this volume the authors offer a comprehensive treatment of all aspects of waste disposal and management. They illustrate these aspects using numerous practical examples. They have included a comparison of regulations in the United States, Canada and Japan, as well as a review of United States environmental legislation - both Federal and State - and a variety of case studies such as Recycling Hawaii and barge wastes.

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.

Wetlands have been used for uncontrolled wastewater disposal for centuries. However, the change in attitude towards wetlands during the 1950s and 1960s caused the minimization of the use of natural wetlands for wastewater treatment (at least in developed countries). Constructed wetlands have been used for wastewater treatment for about forty years. Constructed wetland treatment systems are engineered systems that have been designed and constructed to utilize the natural processes for removal of pollutants. They are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The aim of this book is to summarize the knowledge on horizontal s- surface flow constructed wetlands (HF CWs) and objectively evaluate their treatment efficiency under various conditions. The information on this type of wastewater treatment technology is scattered in many publications but a comprehensive summary based on world-wide experience has been lacking. The book provides an extensive overview of this treatment technology around the world, including examples from more than 50 countries and examples of various types of wastewater treated in HF CWs.

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.

In India, you can still find the kabaadiwala, the rag-and-bone man. He wanders from house to house buying old newspapers, broken utensils, plastic bottles-anything for which he can get a little cash. This custom persists and recreates itself alongside the new economies and ecologies of consumer capitalism. Waste of a Nation offers an anthropological and historical account of India's complex relationship with garbage. Countries around the world struggle to achieve sustainable futures. Assa Doron and Robin Jeffrey argue that in India the removal of waste and efforts to reuse it also lay waste to the lives of human beings. At the bottom of the pyramid, people who work with waste are injured and stigmatized as they deal with sewage, toxic chemicals, and rotting garbage. Terrifying events, such as atmospheric pollution and childhood stunting, that touch even the wealthy and powerful may lead to substantial changes in practices and attitudes toward sanitation. And innovative technology along with more effective local government may bring about limited improvements. But if a clean new India is to emerge as a model for other parts of the world, a "binding morality" that reaches beyond the current environmental crisis will be required. Empathy for marginalized underclasses-Dalits, poor Muslims, landless migrants-who live, almost invisibly, amid waste produced predominantly for the comfort of the better-off will be the critical element in India's relationship with waste. Solutions will arise at the intersection of the traditional and the cutting edge, policy and practice, science and spirituality.

This book provides extensive information on the chemicals that inhabit our environment, our food, our water and our air and the impact that they may be having on human health. The author is a medical scientist, with training in the law. The book documents current understanding about pesticides in food, the plastics revolution, toxic metals, air, water and electronic waste pollutants, chemical exposure in the workplace, radiation pollutants, chemical exposure and hearing loss, how our bodies deal with chemicals, genetic variability and the risk of disease, the effect of chemicals on genes, mitochondria and the immune system and what we can do about it all. Industrialisation has resulted in many thousands of chemicals, which are being continuously developed and often escaping from where they are used into our human environment, without us really knowing enough about them. In high dosages or with continuous small dosage, the evidence suggests, that many of them could interfere with human health and some of them are known to be doing so. But for the vast majority, we are left wondering whether some could be responsible for some diseases the causes of which are inadequately understood. Every chapter is thoroughly reinforced with several pages of references from the peer-reviewed literature.

This broad review is the first to gather comprehensive information on the complete contemporary range of toxicity testing procedures and hazard assessment procedures, which is normally scattered and difficult to find. The two-volume set provides a consistent, template-based approach, linking relevant information on background, theory and practice to each bioassay. Volume 1 covers small-scale toxicity test methods. Includes extensive glossary.

These proceedings provide a forum for chemical scientists and engineers dedicated to making a cleaner, healthier world for everyone. They cover a wide range of related subjects such as environmental monitoring, wastewater treatment, and sludge management.

Christopher Kennedy University of Toronto, Department of Civil Engineering, 35 St. George Street, Toronto, Ontario, Canada M5S IA4 Coal is a valuable resource. It provides a significant amount of the World's energy supply and it is the basis for many industries. However, in areas where coal lies close to the Earth's surface and has been exploited by open cast tech niques, radical alterations of landscape and significant impacts on the envi ronment have occurred. This report was prepared to provide guidance to those who are responsible for the prevention of environmental effects from surface mining and for the restoration of the mining areas. Environmental problems of surface coal mining and restoration of the mine sites are discussed in the re port. Particular attention is given to Eastern Europe, which continues to be a major centre of opencast lignite mining. Reclamation of mined lands for for estry, agriculture and wildlife is briefly discussed. However, the shear volume of coal removed from many mines in Eastern Europe is so vast, that there is often insufficient overburden material to refill the pits. Consequently, the main focus of this report is on the creation of lakes in these former surface mines. Many problems have to be overcome in creating healthy lakes for recreation or wildlife. Guidelines for treating water quality problems and further devel opment of lakes are provided. Techniques for dealing with acidic, waters, eutrophication and contamination are discussed."

Controversies concerning the siting of facilities for the disposal and treatment of hazardous but also domestic waste are widespread in all of the industrialized countries. The paradoxical situation of projects that are needed for environmental reasons and are opposed on environmental grounds has been addressed by scholars and by policy-makers searching for solutions. However, only in a few cases have waste disposal facilities actually been built and made operational. The aim of the book (which illustrates the results of a research project financed by the EU-DGXII) is to investigate the decision-making processes for the siting and creation of waste facilities, in order to identify the factors for predicting success. Adopting a Public Policy Analysis approach the book presents six cases of successful decision-making on waste facilities siting in France, Italy, The Netherlands, Spain, Switzerland and Slovenia, drawing lessons for the redefinition of public policy-making in the field of waste treatment. The conclusions of this book are interesting for all fields of public policy where conflict is a relevant problem. This book is also of interest to scholars in the environmental field, as well as in public policy analysis, and to practitioners and (public or private) actors involved in environmental policy.

Nicolas Buclet and Olivier Godard In terms of economic scale, waste management is one of the two most important environmentally oriented sectors. 1 It stands at the cross-roads in the material organization of society, resource management, changing lifestyles and consumption patterns, and ecological issues. For many years waste management has been perceived as aresources and health issue, confined mainly to dense urban areas, and not an environmental issue. In contemporary affiuent societies, however, the scale reached by waste flows, the inheritance of accumulated deposits in soils from the waste of previous generations and increasing levels of public concern about environmental proteetion and quality of life have all conspired to impose a fresh look at what waste really implies for a modern society. We are obliged to focus our attention on such questions as how the circulation of matter is at present organized by society and can be modified and controlled if economic development is to become more environmentally sustainable. This is the period we live in. Significant changes in waste management in European countries have been introduced during the last decade or so. To some extent the transition between traditional regimes mainly based on local disposal and new regimes based on a revised organisation of flows of waste matter is still in the making, involving new attitudes, new activities, new technologies and new incentives, reducing the pressure on virgin natural resources and eliminating the huge dissipation of various pollutants into the environment.
