Animal agriculture is a major industry in the United States and around the world. Like all major industries, animal operations generate a significant amount of waste by-products, by-products which represent serious potential environmental pollutants. This work is an attempt to help those concerned with animal waste management--agricultural economists and policy-makers, environmental and public health officers, farmers, and so on--deal with this critical issue by addressing the problems generated by animal waste within a comprehensive management approach. As animal production worldwide has taken on the characteristics of an industrial operation, the implications of large quantities of waste--disposal and/or refuse--must be analyzed in environmental, economic, and public health terms. This work provides such an analysis.

This book presents the latest results of global warming researches focusing on Japanese and international efforts. In 2002, Japan initiated Global Warming Research Initiatives lead by the Council for Science and Technology Policy, which aims to harmonize the national research activities and projects. This book is the first report from the initiative. In this book, latest knowledge and future research directions are described for four study areas of the initiative: monitoring and process study, projection modelling and climate change study, impact and risk assessment, and response policies. Readers can review the major topic areas on global warming and climate change. They include the circulation of green house gases in the atmosphere, major results of climate observation, climate prediction made by the Earth Simulator supercomputer, predicted impacts of climate change and future threats, and mitigation and adaptation strategies on climate policy.

This book focuses on the development of DGT (diffusive gradients in thin films) and the related techniques for measuring and investigating the geochemical process and P transfer across the sediment/water or sediment/root interface in lakes. A series of DGT techniques such as new types of probes, test methods in sediment or the rhizosphere, DIFS (DGT induced fluxes in sediments and soils) model for kinetic P exchange, CID (computer imaging densitometry) for S(-II), and microchelex gel/LA-ICP-MS (laser ablation inductively coupled plasma mass spectrometry) have been developed. The corresponding chapters on the theory and methodology of DGT, the "internal P loading" or P transfer across sediment/root in two lakes, provide insights into the research method and conclusions, including the P release mechanism, the quantification of "internal P loading", kinetic P exchange in DGT/sediment interface, Fe- or S(-II)-microniches at submillimeter scales in sediments for the prediction of P release, and DGT as a surrogate for the prediction of P uptake by roots. It also offers new perspectives in the fields of P analysis and P process in micro-interfaces in lakes using DGT techniques. The P remobilization from Fe-bound P, the coupled Fe-S(-II)-P geochemical reaction and algae biomass breakdown causing P release, are elucidated using DGT methods in sediment layers. DGT parameters and curves for time or distance derived from DIFS can be used to assess kinetic P release in the sediment microzone. CID and LA-ICP-MS methods deliver Fe- and S(-II) images at submillimeter scales, which can be used for the quantification of flux related to microniche peaks and the prediction of P release from Fe-microniche or Fe-S(-II)-P geochemical reactions. DGT measurements in-situ in rhizosphere or rhizonbox can give CE (effective concentration) and CDGT values for the prediction of P accumulated in plant tissues. This book provides a valuable reference resource for senior graduate students, lecturers and researchers in the fields of the geochemical process of eutrophic elements in lakes, lake eutrophication mechanism and environmental analysis.

Polar Seas Oceanography describes a new tool called the Generic Model System for simulations and assessment of potential radioactive spreading in the Arctic regions, through rivers, estuaries, regional seas and the Arctic and Atlantic basin. It considers the present and future potential for spreading of radionuclear pollution from sources, such as from the major Russian processing plants through Siberian rivers as well as from European sources such as the UK Sellafield plant. The book provides support for decision making involving risk prevention, forecasting and readiness for probable crises, alerting and detection, relief and mitigation and damage assessment. The book combines the expertise of professionals from the radionuclear and climate-change sciences."

First published in 1987, Peter Brimblecombe's book provides an engaging historical account of air pollution in London, offering a fascinating insight into the development of air pollution controls against a changing social and economic background. He examines domestic and industrial pollution and their effects on fashions, furnishings, buildings and human health. The book ends with an intriguing analysis of the dangers arising from contemporary pollutants and a glimpse of what the future may hold for London.

Identifying and remediating environmental contamination is a complex and very expensive problem worldwide. Pollution of soil and water by pesticides is a significant issue that persists for years after the pesticide application ceases. Pesticide Properties in the Environment is a unique database compiled from extensive literature searches. It presents data on hundreds of pesticides, including their common, commercial, and scientific names, their chemical formulas, and their environmental properties including water solubility, field half-life, sorption coefficient, and vapor pressure. All data is carefully cited to original references, and is presented both in printed form and as an electronic database. Pesticide Properties in the Environment will be invaluable for environmental scientists, engineers, and consultants, as well as soil scientists and water quality specialists.

Hormones and Pharmaceuticals Generated by Concentrated Animal Feeding Operations: Transport in Water and Soil examines how hormones, antibiotics and pharmaceuticals generated from concentrated animal feeding operations (CAFOs) of cattle, poultry, swine and aquaculture are transported in water and soil. Little is known of the environmental fate of the tons of physiologically active steroid hormones released each year. In their own regard, in the last 20 years considerable attention has been given to a wide variety of natural and anthropomorphic agents known as endocrine disrupting compounds (EDCs). Until the contribution of steroid hormones to the environment are better defined, it will be difficult to quantify the exact impact of EDCs. While some advances in the understanding of the fate of these compounds in water has been made, little is known about the processes that govern their transport in soil or how they eventually reach groundwater. As this book discusses extensively, it is somewhat of a mystery how steroids, with their lipophilic nature, strong binding to humic acids and extensive metabolism by soil bacteria, can be transported through even a few centimeters of soil, let alone 20 to 40 meters to the groundwater. With respect to antibiotics, the emphasis is on their fate and transport in the environment and on the emergence of antibiotic resistant bacteria. Impacts on soil ecology, including the impact of antibiotics on the metabolism of other active agents, is also discussed. Similarly, the acaricides and insecticides used in animal husbandry are widely used and their environmental pathways have been studied and have significant impacts on soil and dung ecology. Active compounds with potential environmental impacts, such as growth promoters generated from CAFOs, are described. However, because little is known of their environmental fate, emphasis is placed on defining the gaps in our knowledge and defining their possible effects.

In 2002, the Swedish Metal Information Task Force (MITF) engaged the Environmental Research Group (MFG) to update previous monographs on copper, zinc and major alloying metals (such as chromium, nickel and molybdenum) in society and in the environment. This book presents new results on metal fluxes from society to the environment, on metal speciation in water, soil and sediment, and its interpretation in terms of mobility, biological uptake and toxicity. The scientific fundamentals of new approaches, like the Acid Volatile Sulphide (AVS) concept to predict metal bioavailability in sediments, and the Biotic Ligand Model (BLM) to calculate the toxicity of metals to aquatic organisms, are critically evaluated, with a focus on copper, nickel, zinc, and, in part, chromium.

Recent scientific advances now offer an improved understanding of the mechanisms and factors controlling the intricate behaviour of trace metals, their interactions, uptake and effect in natural systems. Traditional risk assessment methods usually built on quite crude toxicity tests done in unrealistic "laboratory waters," and did not consider natural conditions. In contrast, modern approaches now increasingly involve the full utilisation of site-specific factors, which are decisive for the formation of bioavailable and toxic metal forms.

Audience: This book provides excellent guidance not only to scientists focusing on the assessment of the ecological risk of metals, but also to authorities, decision makers in industry, educational staff and the interested public concerned with the occurrence and fate of trace metals.

Risk assessment has come to assume acute importance in the former Soviet Union since money is so scarce, yet the needs for cleanup are so huge. Other factors contribute to this situation, too: New leaders are still emerging, and governmental structures are still evolving. This creates a particular difficulty for environmentalists who attempt to become involved in the risk assessment process. New information continues to surface on the fallout from Chernobyl and its consequences for human health. Scientists are still debating the effects of low doses of radiation delivered over a long period of time. This type of contamination is especially prevalent in the Russian North, for example, as a result of the dumping of nuclear submarine reactors into the Kara and Barents Seas. This book examines the complexities of risk assessment in the FSU at this unique time in history.

Humans are exposed daily to low concentrations of metals that are released into the environment by both natural and industrial processes. Environmental Metal Pollutants, Reactive Oxygen Intermediaries and Genotoxicity: Molecular Approaches to Determine Mechanisms of Toxicity examines concerns about the acute and/or chronic exposure of humans to concentrations of these metals that are below the threshold levels established by various federal regulatory agencies. Some of these metals are accumulated in various tissues and over time this may result in the accumulation of a significant body burden. This could increase the risk of developing a variety of diseases later in life, at a time when thresholds for such effects may already be reduced by the processes of aging. Such possibilities could only further compromise the quality of life in the elderly population and could contribute to the rising cost of health care in this country. Studies that have been conducted to determine the possible risks associated with exposure to relatively non-toxic concentrations of environmental metals have been hampered by a lack of appropriate models and a lack of funding. It has also been difficult for researchers to demonstrate a correlation between the exposure of humans or animals to low concentrations of environmental pollutants and disease. This book examines recent technological advances in the areas of molecular biology, biochemistry, and computer-enhanced image analyses that provide researchers with the tools to begin elucidating the genotoxic effects of environmental metal pollutants and the mechanisms by which these metals cause DNA damage. Environmental Metal Pollutants, Reactive Oxygen Intermediaries and Genotoxicity: Molecular Approaches to Determine Mechanisms of Toxicity presents data that demonstrate that certain environmental metal pollutants are genotoxic. The authors describe the role of reactive oxygen intermediates in causing the DNA damage induced by environmental metal pollutants and discuss their possible role in human disease.

The book contains the contributions at the NATO Study Institute on Exposure and Risk Assessment of Chemical Pollution - Contemporary Methodology, which took place in Sofia - Borovetz, Bulgaria, July 1-10, 2008. Rapid advances in mathematics, computer science and molecular biology and chemistry have lead to the development in of a new branch of toxicology called Computational Toxicology. This emerging field is addressing the estimation and prediction of exposure risk and effects of chemicals based on experimental data, measured concentration and biological mechanisms and computational models of biological systems. Mathematical models are also being used to predict the fate and transport of substances in the environment. Because this area is still in its infancy, there has been limited application from governmental agencies to regulating controllable processes, such as registration of new chemicals, determination of estimated exposure and risk based limits and maximum acceptable concentrations in different compartments of the environment - ambient air, waters, soil and food products. However, this is soon to change as the ability to collect, analyze and interpret the required information is becoming increasingly more efficient and cost effective. Full implementation of the new processes have to involve education on both part of the experimentalists who are generating the data and the models, and the risk assessors who will use them to better protect human health and the environment.

Understanding urban air pollution is a prerequisite to finding effective solutions to air quality problems and for a sustainable development in the urban environment. In this book the current state of the art in urban air pollution research is presented. A major focus is on suitable air pollution modelling concepts, covering also street canyon geometries. Such models may be applied to establish source-receptor relationships in support of urban air quality management. Procedures for evaluating the performance of air pollution models are proposed, and results from field experiments and laboratory studies are shown to provide better insight into the characteristics of air pollution at the urban and local scales. The contents of this book are of a high policy relevance, given their direct connection to the formulation of improved tools for urban air quality assessments.

Numerous studies have revealed that the poor disproportionately bear the burden of environmental problems in America today. Issues range from higher levels of poisonous wastes, carbon dioxide, and ozone, to greater than normal incidences of asthma and lead poisoning. The environmental justice movement, which has emerged in working class and low-income African American and Latino communities since the early 1990s, is an effort that is reinterpreting the definition of the environment as "where we live, work, and play" to connect new constituencies traditionally outside of the postwar environmental movement. Novotny documents this expanding constituency through case studies of four community groups ranging from South Central Los Angeles to Louisiana. "Environmental racism" is understood as yet another type of discrimination which results in a high incidence of environmental concerns in poorer communities due to what many activists see as discriminatory land use practices, decisions by industry that intentionally locate hazardous wastes in these communities, and the uneven enforcement of environmental regulations by federal, state, and local officials. Community leaders have added environmental causes to their fight against unemployment, impoverishment, and substandard housing. This study explores various attempts to put a halt to illegal practices and to broaden public awareness of the issues involved.

A huge effort is put into the science of nanoparticles and their production. In many cases it is unavoidable that nanoparticles are released into the environment, either during the production processes or during the use of a product made from these particles. It is also realized that combustion processes like traffic and power plants release nanoparticles into the atmosphere. However it is not known how nanoparticles interact with the human body, especially upon inhalation. At the same time research activities are devoted to understand how nano-sized medicine particles can be used to administer medicines via inhalation. In any case it is absolutely necessary to know how the nanoparticles interfere with the inhalation system, how they deposit and affect on the human system.

Three main themes are discussed:

• Nanoparticle sources and production
• Nanoparticle inhalation and deposition
• Toxicological and medical consequences of nanoparticles

Each theme is covered comprehensively, starting at nano-quantum effects up to technical and medical applications such as measuring equipment and inhalation instrumentation. This book brings together all sub-disciplines in the field related to aerosol nanoparticles. Each chapter is written by a world expert, giving the state of the art information and challenging open questions. The last chapter summarizes in an interdisciplinary way what is already known and what still is ahead of us.

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of xenobiotics in any segment of the environment, as well as toxicological implications.

Pesticides Remediation Technologies from Water and Wastewater focuses on environmental aspects and health effects of pesticides, the use of conventional and AOPs technologies, and adsorption processes and nanomaterials for the removal of pesticides from water and wastewater. The deterioration of water quality is of great concern due to its effects on aquatic organisms, humans and the ecosystem. Among the pollutants, pesticides are a major concern in villages and farm land. This edited book bridges the gap between old and new knowledge about the categorization of pesticides, the presence of them in water, wastewater, soil and foods, and new methods to detect them from water matrices. This edited book provides the necessary basic knowledge to new researchers who want to learn about pesticides and the ways to eliminate them in aqueous matrices. Moreover, it is also a helpful resource for mature researchers in this field, providing them with new trends in water and wastewater treatment processes, preparation and application of novel adsorbent materials.

(Received November I, 1984; revised May 14, 1985) Abstract. An integrated, interdisciplinary, intensive study of three forested watersheds in the Adirondack Park region of New York State was started in 1977 to quantify the relationship between the deposition of atmospheric acids and surface water acidity. A general mechanistic theory of lake-watershed acidification that takes into account the production and consumption of acidity by watershed processes, as well as atmospheric inputs of acidity, was developed. This theory is formulated as a mathematical simulation model. Model and data analyses establish the importance of using an integrated ecosystem perspective to assess the vulnerability of surface waters to acidification by acidic deposition. The acid-base status of surface waters is determined by the interaction of many factors: soil, hydrologic, vegetation, geologic, climatic, atmospheric. The absolute and relative contribution of any given factor can be highly variable, both geographically and temporally; hence, lake sensitivity to changes in the quality and quantity of atmospheric deposition is also highly variable.

Managed ecosystems cover a large part of the Earth's land surface, provide almost all of our food and most of our wood and fibre, and are increasingly a source of renewable energy. Forecasting the ability of managed ecosystems to continue these vital roles in a globally changing environment is an inter-disciplinary challenge.

To elucidate the complex responses of managed systems to elevated CO2], several free air carbon dioxide enrichment (FACE) facilities were established. These FACE systems allow large areas to be exposed to the elevated CO2] we expect by the middle of the century. This volume summarizes the main findings from 13 experiments with annual crops, permanent pastures and plantation forests at 11 sites throughout the world during the past ten years. The results significantly alter our perception of how rising CO2] will directly affect these managed ecosystems, with implications for policy, plant-breeding objectives and adaptation.

The Economics of Pollution Control in the Asia Pacific adapts environmental economics to the special conditions of the Asia Pacific region, emphasizing the importance of local conditions and culture. Global warming, air pollution and water pollution are all addressed by a distinguished group of authors who rigorously apply economics to the analysis of pollution control in societies undergoing rapid industrialization. As this pioneering volume demonstrates, citizens of rapidly developing Taiwan and Korea are willing to pay substantial amounts for the protection and improvement of air and water quality, and face potentially huge losses from global climate change. A number of the papers also point to some cost effective alternatives for helping to reduce global greenhouse gas emission. As this major book reveals, the make-up of Asian politico-economic systems has a direct impact on environmental policies, from benefit estimation to instrument choice. As the authors argue, policymakers and researchers in the Asia Pacific cannot draw on European and American methods, arguments and conclusions without considerable modification for regional conditions.

In this urgent time, World on the Edge calls out the pivotal environmental issues and how to solve them now. We are in a race between political and natural tipping points. Can we close coal-fired power plants fast enough to save the Greenland ice sheet and avoid catastrophic sea level rise? Can we raise water productivity fast enough to halt the depletion of aquifers and avoid water-driven food shortages? Can we cope with peak water and peak oil at the same time? These are some of the issues Lester R. Brown skilfully distils in World on the Edge. Bringing decades of research and analysis into play, he provides the responses needed to reclaim our future.

Dry sulfurization processes offer the significant advantages of low capital and low operating costs when compared to wet desulfurization. They hold great potential for the economical reduction of sulfur emissions from power utilities that use high-sulfur coal. Dry Scrubbing Technologies for Flue Gas Desulfurization represents a body of research that was sponsored by the State of Ohio's Coal Development Office for the development of technologies that use coal in an economic, environmentally-sound manner. One of the project's major goals was the development of dry, calcium-based sorption processes for removing sulfur dioxide from the combustion gases produced by high-sulfur coal. Dry Scrubbing Technologies for Flue Gas Desulfurization highlights a number of fundamental research findings that have had a significant and lasting impact in terms of scientific understanding. For example, the experimental investigation of the upper-furnace sulfur capture obtained time-resolved kinetic data in less than 100 millisecond time-scales for the first time ever, thereby revealing the true nature of the ultra-fast and overlapping phenomena. This was accomplished through the development of a unique entrained flow reactor system. The authors also identify a number of important areas for future research, including reaction mechanisms, sorbent material, transport effects, modeling, and process development. Dry Scrubbing Technologies for Flue Gas Desulfurization will appeal to both chemical and environmental engineers who examine different ways touse coal in a more environmentally benign manner. It will make an essential reference for air pollution control researchers from coal, lime, cement, and utility industries; for government policy-makers and environmental regulatory agencies; and for those who teach graduate courses in environmental issues, pollution control technologies, and environmental policy.

In the continuing fight against organic environmental xenobiotics, the initial success attributed to bioremediation has paled, in part due to the low availability of xenobiotics entrapped within a soil or sediment matrix. This has generated a very significant wave of interest in the bioavailability issue. However, much experimental evidence is puzzling or contradictory, mechanistic theories are embryonic, and implications for the practice of bioremediation or concerning the natural fate of xenobiotics are still tentative. The debate in Europe and the USA is vigorous. Eastern Europe, following the liberalisation of the economy and political life, is evolving in a similar direction. In many cases, however, limited access to literature sources, severe language barriers, and the lack of a strong pluridisciplinary tradition are hampering the adoption of state of the art techniques. Originally intended to allow scientists in East European countries to become acquainted with the key aspects of the bioavailability debate that is unfolding in the scientific literature in the West, and with its implications for bioremediation efforts, the present book presents a very complete coverage of the theoretical and practical aspects of the (limited) bioavailability of organic xenobiotics in the environment.
