Foodandwatersecurityissuesareregardedassinequanonif asocietywants to p- mote health, peace and prosperity. People who are well fed are also people with the means to changetheir situation. However, this is still an immense challengefor Asia especiallyintheglobalenvironmentalperspectiveinthe21stcentury. Peoplearound the globe will be facing a combination of problems concerning both environmental as well as social changes; therefore, the policy for future food and water security has to be upgraded in an integrated and holistic way. The need to put into persp- tive the ever-mounting body of new information on environmental security of food and water issues in Asia beyond the boundaries of separate disciplines provided the impetus for the development of this book. It is a compilation of selected ar- cles from two international symposiums entitled "Food and Water Sustainability in China 2007" and "Food and Water Sustainability in Asia 2008" which were held in Macau, China. Eminent scientists/researchers from different parts of Asia spoke at the symposium on topics such as the challenges in sustainable water resource m- agement, future projection of development strategies for sheries, increased yield of food grains by rainwater management in arid lands, multi-functional role of rice paddy area for food and water sustainability, the impact of biofuel production on food security, reclaimed wastewater for sustainable urban water use, heavy metal removal from contaminated soil and water, and adaptation strategies to cope with the climate change issues for food and water.

There is not an extensive literature on street sweeping. Much of the research that has been completed exists in the "gray" area of technical reports and government documents. Furthermore, a great deal of this research is locally based, and has not been widely published. Indeed, our review of the scientific literature, revealed that, while storm water quality has received a lot of attention, few academicians have been involved in street sweeping research per se. Thus, throughout our research into street we sweeper effectiveness, sweeping protocols, and sweeping practices, wished that there had been a book summarizing some of the important issues associated with street sweeping. As our frustration grew, we realized that we were uniquely poised to write such a book as our research had encompassed a variety of different projects including sweeper testing, waste management, and related storm water quality. Also, early on in this exercise, we recognized that there was a growing demand for information about street sweeping policies and management, especially for studies focusing on the effectiveness of different sweeping schedules, on waste management operations, and on non-point, pollution reduction practices associated with storm water runoff. It was abundantly clear that there was a profound lack of research on street sweeping that could assist with developing local, regional, or national policies. There was, in effect, little guidance for city managers on these issues.

Lake Mendota has often been called "the most studied lake in the world. " Beginning in the "classic" period of limnology in the late 19th century and continuing through the present time, this lake has been the subject of a wide variety of studies. Although many of these studies have been published in accessible journals, a significant number have appeared in local monographs and reports, ephemeral documents, or poorly distributed journals. To date, there has been no attempt at a synthetic treatment ofthe vast amount of work that has been published. One intent of the present book is to present a com prehensive compilation of the major early studies on Lake Mendota and to examine how they impinge on important present-day biological questions. In addition, this book presents a summary of field and laboratory work carried out in my own laboratory over a period of about 6 years and shows where correlations with earlier work exist. The book should be ofinterest to limnologists desiring a ready reference to data and published papers on this important lake, to biogeochemists, ocean ographers, and low-temperature geochemists interested in lakes as model sys tems for global processes, and to lake managers interested in understanding short-term and long-term changes in lake systems. Although the major thrust ofthe present book is ecologicaland environmental, sufficient background has been presented on other aspects ofLake Mendota's limnology so that the book should also be useful to nonbiologists."

Leading experts present methodologies for basinwide approaches to water quality restoration. In 15 chapters the identification of pollution sources, definition of standards and their attainability, surface and groundwater modeling, remediation of contaminated soils and sediments, development and implementation of low cost treatment technologies, basinwide water quality management and remediation, and economic and institutional issues are covered. The book focuses on the situation in central and eastern European countries; however, the topics and solutions are of general interest and have worldwide applications.

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 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."

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.

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.

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."

This book focuses on sustainable solid waste management in an urban context and gives an example of how a modern city can work with waste management for increased sustainability in close cooperation with the academy. The book describes challenges which the city is facing and presents a case on how these can be tackled based on several research and development projects performed in the City of Malmoe over the last decade. In these projects, the city has worked as a test bed for new solutions, developed with and evaluated by the university. The projects and evaluations of the same have been developed with a multi-dimensional approach; including technical aspects, resource efficiency, economic parameters, information strategies towards households and user friendliness. Methods used for evaluation are presented in a comprehensive way together with a discussion on how results from performed evaluations have affected the solid waste management policy making in the city. The book describes a bridging over a commonly noticed gap between research on the one hand and policy making and technical management on the other. Several examples are given on how academy and real life and full-scale developments in the city can have a fruit-full collaboration, where feed-back from evaluation of made changes are used for continuous improvements - at the same time as the actual needs from the city forces the academy to develop new methods for evaluations and develop new solutions to previously un-known or un-addressed problems.

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."

Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary subject, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occuring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about one hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities ofwaste in relatively small and confined areas. Much of the chemical products and was te products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems."

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."

Modelling of hydrological rainfall-runoff processes is facilitated by the application of the systemtheoretical approach to linear, nonlinear and stochastic models. To this purpose, the variables involved in methods for determinating areal precipitation and baseflow separation are discussed. The convolution theorem in the theory of linear systems and the mathematical transform technique (Laplace-, Z-transformation) are used to identify characteristics of the watershed, and simulate hydrological processes. To support the calculation of model output functions, computer programs are included in the text. This volume is suitable as a text for hydrology courses at universities or engineering academies.

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."

Following the events of 9/11, the Administrator of the US Environmental Protection Agency created the Water Protection Task Force (WPTF), which identified water and wastewater systems as a major area of vulnerability to deliberate attack. The WPTF suggested that there are steps that can be taken to reduce these vulnerabilities and to make it as difficult as possible for potential saboteurs to succeed. The WPTF recommended that be scrutinized with renewed vigor to secure water and wastewater systems against these possible threats. It also recommended that water and wastewater systems have a response plan in place in the event an act of terrorism occurs. The WPTF identified water distribution networks as an area of special vulnerability and highlighted the need for rapid on-line detection methods that are accurate and have a wide detection range. As a result of these recommendations novel technologies from various fields of science and engineering are now addressing water security issues and water and wastewater utilities are looking for innovative solutions. Once such technologies are available, there will be a rapid implementation process that will present many business opportunities for the private sector. However, in addition to terrorist threats water and wastewater systems are inherently vulnerable to natural disasters such as earthquakes and floods. This volume will address the problems associated with both intended terrorist attacks and natural disasters affecting water or wastewater systems. The book is divided into parts based on the kinds of threats facing water and wastewater systems: (1) a direct attack on water and wastewater infrastructure storage reservoirs, and distribution and collection networks; (2) a cyber attack disabling the functionality of the water and wastewater systems or taking over control of key components which might result in system failures; and (3) a deliberate chemical or biological contaminant injection at one of the water distribution system's nodes. It will examine unique plans, technological and managerial innovations for protecting such systems, and includes descriptions of projects that were implemented to respond to natural disasters. Case studies are presented that discuss existing projects and evaluate their performance, with an emphasis on providing guidelines and techniques that can be implemented by water and wastewater planners and managers to deal with natural and manmade disasters should they occur.

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.
