This book presents the results of thirty-four case studies in an EU-sponsored project on heavily modified water bodies. The account emphasizes the methods used in the process of identification and designation, and identifies further research needs. The contents are the basis for the agreed European Guidance on artificial and heavily modified water bodies to be used by practitioners in the implementation of the Water Framework Directive.
The main subject of the Workshop was the new developments about the cost effective treatment techniques for better removal efftciencies and dis cussion of policies for pollution control. Although effluent water quality requirements differ from one country to another, their application will be an efficient mean for water pollution control. Specific promotion should be provided for polluters to meet the effluent water quality requirements. Results of pilot scale studies demonstrate the applicability of and ad vantages of sequenching batch reactor technology for pretreatment of in dustrial wastewaters Fixed film biological reactors offer the possibility to enrich slow growing specialized microorganisms by developing biofilms on support materials. Physical chemical processes are used for the treatment of unusual and difficult industrial wastewaters and membrane technologies for the con centration and recovery of raw materials and by-products, in industries where the conventional treatment technologies are inappropriate or uneco nomic Physical chemical processes give higher efficiencies when polymers are applied but the composition of these long chain chemicals is an im portant consideration; Most developing countries suffer from severe environmental problems and shortage of energy and resources. These countries urgently need simple, inexpensive and integrated environmental protection system, which combine wastewater treatment with recovery and reuse. Anaerobic treatment offer many advantages in this respect. Because recovery of substances from wastes serves twofold purpose of recyle and pollution control, it must be applied where possible."
The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring." Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.
Integrated Water Resources Management (IWRM) is an approach that promotes the coordinated development and management of water, land and related resources, in order to maximize economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems. Without public interest and participation, successful implementation of IWRM plans for river basin cannot be possible. Further to this, management at the watershed level to assure water supplies to support livelihood (i.e. domestic water, irrigation, industries, etc.) and sustainable groundwater development requires water augmentation through water conservation structures, and pollution control will also play a vital role. In India, because of limited period of rainfall during Monsoon (i.e. three to four months), water conservation and rainwater harvesting have been practiced since ancient days in order to meet water demands throughout the year. These structures are generally constructed and operated through the public participation. Keeping in view of the importance of public partnership, the role of public partnership in context of water-related awareness and practices has been investigated in different parts of the Yamuna River basin. The investigation evaluates the impact of various water conservation devices on livelihood; compares the performance of recently developed water conservation structures with ancient structures; examines spatial variation of water-related problems in the basin; and proposes an institutional setup for effective governance.
The work aims at answering the question as to how far discourses on human security are present in Jordan and Israel, if they converge and if political solutions for the issue of water security could be derived. The analysis is based on the assumption that from human security perspective common solutions for urgent problems can be derived more easily than out of a perspective of national security. Yet it is acknowledged that according to a new security perspective different security threats are being identified by relevant actors. An empirical analysis of written statements and utterances of the respective security elites establishes the methodological tool for the identification of human security discourses in Israel and Jordan. Subsequently it is estimated how far water is presented as a matter of national security in Israel and Jordan using the theory of securitization.
Based on a symposium sponsored by the Environmental Division of the American Chemical Society, Perchlorate in the Environment is the first comprehensive book to address perchlorate as a potable water contaminant. The two main topics are: analytical chemistry (focusing on ion chromatography and electrospray ionization mass spectrometry), and treatment or remediation. Also included are topics such as ion exchange, phytoremediation, bacterial reduction of perchlorate, bioreactors, and in situ bioremediation. To provide complete coverage, background chapters on fundamental chemistry, toxicology, and reulatory issues are also included. The authors are environmental consultants, government researchers, industry experts, and university professors from a wide array of disciplines.
A survey of the feasibility of aircraft- and satellite-based methods for revealing environmental-geological problems. Throughout, a balanced ratio between explanations on the methodological/technical side and presentations of case studies is maintained. The comparison of case studies from North America and Germany shows how the respective territorial conditions lead to distinct methodological approaches. Equally, the considerable dissimilarities in population density and in distances between waste disposal areas, settlements, and areas of protected groundwater necessitate a "diversified methods" approach.
The majority of this book was written in 1983-84 while the senior author was a Visiting Scientist at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. We believe that the approach to the problem of acid deposition effects on soils and waters developed during this collaboration contains ele ments that are significantly different from most prior work in this area. Some of the material and the software used in the development of these concepts stem from earlier individual efforts of the authors. However, what we believe to be the more significant concepts concerning the processes by which alkalinity may be developed in acid soil solutions, and by which acid deposition may contrib ute to the loss of this alkalinity, were the result of this collaboration. The ultimate usefulness of these concepts in understanding and dealing with various aspects of the problems associated with acid deposition cannot be adequately gauged at the present time. They must first withstand tests of con sistency with available observation, and of direct experimentation. It is our hope that dissemination through this book will facilitate this process within the scientific community. The authors wish to thank the administration of the Environmental Science Division at ORNL, and the College of Agricultural Sciences at Colorado State University for their support in arranging this collaboration. We also wish to express our appreciation for the financial support provided by EPA. Personal thanks are due to Dr."
A review of such natural disasters as floods and landslides, highlighting the possibility of safe and correct land planning and management by means of a global approach to territory. Since the events deriving from slope and fluvial dynamics are commonly triggered by the same factor, occur at the same time and are closely related, this book analyses floods and slope stability phenomena as different aspects of the same dynamic system: the drainage basin.
The ffiM Japan International Symposium Energy and Environment - Global Warming was held in the Keidanren Guesthouse at the foot of Mt. Fuji, from October 21 to 24, 1990. The symposium was conducted in the context of ffiM Japan's longstanding commitment to good corporate citizenship. On this beautiful planet with its inter-dependent waters, lands and atmo sphere, we consider that the problems relating to the global environment are the most serious that the human race will face in the near future. The symposium provided an opportunity for forty scientists and researchers, from a wide variety of international backgrounds, to address matters relating to the global environment in an international forum. Eighteen papers were presented followed by panel and group discussions, on which the concluding remarks and recommendations are based. We chose three types of papers to target different aspects of the condition of the global environment: the natural science component; the socio-economic component; and the energy component which links these two. On the first day the symposium began with a plenary speech by Dr. J. Kondo followed by three keynote speeches, each with a particular focus. The following day, six speakers offered papers relating to the previous day's keynote speeches."

New institutions don't come into being by themselves: They have to be organized. On the basis of research from a decade-long, multi-site study of efforts to transform freshwater management in Brazil, Practical Authority asks how new institutional arrangements established by law become operational in practice. The book explores how this happens by putting both agency and structures in motion. It looks at what actors in complex policy environments actually do to get new institutions off the ground. New configurations of authority in a policy area very often have to be produced relationally, on the ground, in practice. New organizations have to acquire problem-solving capabilities and recognition from others, what the authors call "practical authority." The story told here has a multiplicity of protagonists, many of whom are normally invisible in political studies, such as the state officials and university professors who struggled to move water reform forward. The book explores the interaction between their efforts to influence the design and passage of new legislation and the hard labor of creating the new water management organizations the laws called for. It follows three decades of law making at the national and state level and examines the creation of sixteen river basin committees throughout the country. By bringing together state and society actors around territorially specific problems, these committees were expected to promote a new vision of integrated water management. But none of the ones examined here followed the trajectory their organizers expected. Some adapted creatively to challenges, circumventing roadblocks encountered along the way; others never got off the ground. Rather than explain these differences on the basis of the varying conditions actors faced, the authors propose a focus on the process, and practice, of institution building.
Who Speaks for the Oceans? The question has been asked a lot in recent years - just who is looking out for our oceans? Covering over seventy percent of the earth's surface it is the world's largest common property resource, jojntly owned by over six billion humans. It is the foundation for life on earth as we know it. Over the years, many people have spoken about various aspects of our ocean environments and they have spoken to different audiences in many different ways. For many in the public realm, Jacques Cousteau spoke for the ocean. Since his passing, no single voice with the sallle public identity or recognition has emerged. Certainly the many governments bordering our oceans cannot agree on common principles or issues of ocean use and management. We might be tempted think that we do not have an ocean spokesperson or champion, but we would be wrong. Today, the rapidly growing number of scientists working hard to expand our under standing of our ocean realm are the ocean voices we should listen to. At the same time as our scientists advance their understanding of the oceans, we all need to advance our abilities and commitment to communicate on behalf of the oceans with broader and broader audiences who need to be aware of where things stand. Often called "the last great frontier," earth's oceans are vast, widely varied, and are hard to get to, arid into, to do the research we need done."
Corrosion has been largely considered to be caused only abiotically, without regard of any biological influence. However, corrosion of organic materials, metals, minerals and plastics can be strongly influenced by microorganisms, enhancing the kinetics of the corrosion processes. This book presents case histories, theoretical explanations, and methods for the detection, sanitation and prevention of biologically influenced corrosion.
various places of the world. Thus, it is hoped that this up-to-date subseries would increase the "awareness" of the world's citizens and encourage governments to devote more attention and resources to address this issue. The series editors thank the international panel of contributors for bringing this timely series into completion. We also wish to acknowledge the very insightful input of the following colleagues: Prof. A. L. Page ofthe University of California, Prof. T. C. Hutchinson of the University of Toronto, and Dr. Steve Lindberg of the Oak Ridge National Laboratory. We also wish to thank the superb effort and cooperation of the volume editors in handling their respective volumes. The constructive criticisms of chapter reviewers also deserve much appreciation. Finally, we wish to convey our appreciation to my secretary, Ms. Brenda Rosier, and my technician, Ms. Claire Carlson, for their very able assistance in various aspects of this series. Aiken, South Carolina Domy C. Adriano Coordinating Editor Preface to Acidic Precipitation, Volume 4 (Advances in Environmental Science) Acidic precipitation and its effects have been the focus ofintense research for over two decades. Initially, research centered on the acidity status and acidification of surface waters and consequent impact on the status of sports fisheries; evidence suggested impacts on fisheries in Sweden and Norway, and in North America, in eastern Ontario, Quebec, and in the Adirondack Mountains of New York.
Brominated flame retardants are one of the last classes of halogenated compounds that are still being produced worldwide and used in large quantities in many applications. They are used in plastics, textiles, electronic circuitry, and other materials to prevent fires. This volume covers the state-of-the-art of the analysis, fate and behaviour of brominated flame retardants. Experts in the field provide an overview of the compounds physico-chemical properties and uses, their occurrence in the environment and biota, advanced chemical analytical methods, degradation studies, toxicological effects and human exposure. This book is a valuable and comprehensive source of information for environmental scientists interested in brominated flame retardant issues, and for authorities and producers."
When, in 1966, the Gennan Research Society directed the attention of oceanographers in the Federal Republic of Ger many to problems of marine pollution, I was not enthusiastic. Emphasis on this problem area meant that other important research plans had to be postponed. But the lectures at the Third International Oceanographic Congress, September 1970, in Tokyo, and at the FAO Conference on Marine Pollution and its Effects on Living Resources and Fishing, December 1970, in Rome, convinced me that research on problems of marine pollution is a social obligation, and that the oceanographer has to take a stand. I issued public warnings about the continuing use of pesticides and had to defend myself against protests by the fishing industry and many colleagues who were, in Novem ber 1970, unaware of the extent of the threat. Thus, I was required by my profession to acquire an overview of the prob lems of ocean pollution. In 1971 I only needed to familiarize myself with some one hundred bibliographical items. In the interim, the flood of data has risen dramatically, and in the year 1975, no fewer than 868 publications under the heading of "Marine Pollution" were reported (Table 1). It is, therefore, more and more diffi cult to distinguish new results of scientific research from the many repetitions and variations, and I fear that from year to year my efforts to illustrate the actual status of the problem at a given moment will be subject to more gaps."
International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic en vironments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on "toxic" chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic an imals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxicology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature pro duced by these emerging areas of science together with documentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individuals need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching."
Current research revolves around trends to bring technology into harmony with the natural environment and in order to protect the ecosystem. Bioremediation involves processes which reduce the overall treatment costs by using agricultural residues. Regeneration of the biosorbent further increases the cost effectiveness of the process, thus warranting its future success in solving water quality problems. Special emphasis is paid to chemical modifications resulting in tailored novel biomaterials which improve its sorption efficiency and environmental stability. In this way it can be used commercially as a simple, fast, economical, ecofriendly green technology, for the removal of toxic metals from waste water particularly in rural and remote areas of the country.
Drinking water quality has been a matter of concern for several decades. Disinfection of drinking water improves its microbiological quality and prevents disease outbreaks. However, continuously increasing scientific research concerns the presence of organic and inorganic contaminants in water. Many of these compounds, named haloforms, originate from the procedure of disinfection, being formed during reactions of disinfectants with natural organic matter present in water. Haloforms may possess carcinogenic or mutagenic properties; therefore minimization of their concentrations in drinking water is a critical issue. Regulatory measures are becoming more and more stringent, as new health effects become known and optimized high-sensitivity analytical methodologies are being developed. Up-to-date research findings concerning all these aspects have been collected, critically reviewed, summarized, and are presented and discussed in the present book.
Water scarcity affects hydrologic resources, systems connectivity, biodiversity, water quality, and river ecosystem functioning. It has direct impacts on economic sectors that use and depend on water, such as agriculture, tourism, industry, energy and transport. The Mediterranean Basin is one of the regions in the world most vulnerable to climate changes, as well as one of the most impacted by human water demand. This volume provides an in-depth view of the water quality and quantity implications of water scarcity. It highlights its possible causes and describes the effects in regions under Mediterranean climate. The topics covered include climate effects, water resources (use, storage and new sources), water quality (chemical and microbiological), and the effects on ecosystems suffering from water scarcity. This book is addressed to scientists and students, but also to managers involved in the necessary decision making process to face future periods of drought.
The history of chemistry and pharmaceutical sciences is an impressive success story. The products of chemical and pharmaceutical industries are present eve- where in our everyday life. They help to pursue the modern way of living and they contribute to our high standard of living and safety, mobility, communication te- nologies, food, health, textiles and drinking water treatment, among many others. These products are labeled under the categories: pharmaceuticals, pesticides, det- gents, fertilizers, dyes, paints, preservatives, food additives and personal care pr- ucts, to name a few. Within these categories, groups of chemicals with similar structures can be found. However, often groups of chemicals with very different structures belong to the same category. For a long time the production of chemicals and pharmaceuticals, their usage and application was connected with the heavy pollution of the environment and serious health effects. At the end of the last century, it was realised that the products of che- cal and pharmaceutical industries are presenting a new type of environmental pol- tion that may also pose a health risk to the consumer. Most chemicals are used in so-called open applications in excessive amounts e. g. for personal care, hygiene, plant protection, health and in textiles. In many cases such as scents, detergents, textile chemicals, surface disinfectants, pesticides and others it is unavoidable that these chemicals are released into the environment according to their intended use.
The goal of the book is to examine scientific advances since 2000 that may have increased understanding and options in three general areas related to hypoxia: Characterization the Cause(s) of Hypoxia. The physical, biological and chemical processes that affect the development, persistence and extent of hypoxia in the northern Gulf of Mexico. Characterization of Nutrient Fate, Transport and Sources. Nutrient loadings, fate, transport and sources in the Mississippi River that impact Gulf Hypoxia. Scientific Basis for Goals and Management Options. The scientific basis for, and recommended revisions to, the goals proposed in the Action Plan; and the scientific basis for the efficacy of recommended management actions to reduce nutrient flux from point and nonpoint sources. In addressing the state of the science, the book focuses on the strengths and limitations of the science in managing the Gulf hypoxia problem, including available data, models and model results and uncertainty. It includes work from the following authors: C. Kling, Iowa State University, Ames, IA, USA; J.L.

Most of the world s mountains are rich in water and, as such,
play a pivotal role in the global water cycle. They provide water
for diverse human uses and ecosystems. Growing water demands as
well as climate change will lead to ever-increasing pressure on
mountain waters. Overcoming water-use conflicts and maintaining the
ecological functioning of mountain waters presents a highly
challenging task and is indispensable for sustainable
development.
Water scarcity and the need for ecological sustainability have led to the introduction of treated waste water as an additional water resource in the national water resource management plans of Mediterranean countries. Summarizing the results generated within the European Union-funded project "INNOVA-MED, "this volume highlights the following topics: Application of innovative technologies and practices for waste water treatment and reuse adapted to the Mediterranean regionConstraints on the application of advanced treatments and reuse of reclaimed water and sludgeProblems and requirements of sustainable water management in the Mediterranean area The book includes several examples of Mediterranean countries, such as Tunisia, Morocco, Egypt, Palestine and Spain, and presents their practical experiences in the application of innovative processes and practices for waste water treatment and reuse.
