With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the potential for seawater to become increasing acidic (i.e., ocean acidification). Scientists are concerned that increasing acidity could result in reduced growth or even death of shell-forming animals as well as disruption of marine food webs and reproductive physiology. Congress is beginning to focus attention on better understanding this issue and determining how it might be addressed. As well as examining the above issues, this book also presents an overview of the causes of hypoxia, the U.S. areas of most concern, federal legislation, and relevant research programs. In addition, this book reviews the history and oil spills in the United States; identifies the legal authorities governing oil spill prevention, response and cleanup; and examines the threats of future oil spills in U.S. coastal waters. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.

Nationally-recognised studies and our contacts with a diverse group of industry representatives, non-governmental organisations, and academic researchers show that key barriers to CCS deployment include (1) underdeveloped and costly CO2 capture technology and (2) regulatory and legal uncertainties over CO2 capture, injection, and storage. Among the key technological barriers are a lack of experience in capturing significant amounts of CO2 from power plants and the significant cost of capturing CO2, particularly from existing coal-fired power plants, which are the single largest source of CO2 emissions in the United States. Compounding these technological issues are regulatory and legal uncertainties, including uncertainty regarding liability for CO2 leakage and ownership of CO2 once injected. According to the IPCC, the National Academy of Sciences, and other knowledgeable authorities, another barrier is the absence of a national strategy to control CO2 emissions (emissions trading plan, CO2 emissions tax, or other mandatory control of CO2 emissions), without which the electric utility industry has little incentive to capture and store its CO2 emissions. Moreover, according to key agency officials, the absence of a national strategy has also deterred their agencies from addressing other important practical issues, such as resolving how stored CO2 would be treated in a future CO2 emissions trading plan.

Fly ash is one of the residues generated in the combustion of coal. Fly ash is generally captured from the chimneys of coal-fired power plants, and is one of two types of ash that jointly are known as coal ash; the other, bottom ash, is removed from the bottom of coal furnaces. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline) and calcium oxide (CaO). Toxic constituents include arsenic, beryllium, boron, cadmium, chromium, chromium VI, cobalt, lead, manganese, mercury, molybdenum, selenium, strontium, thallium, and vanadium, along with dioxins and PAH compounds. In the past, fly ash was generally released into the atmosphere, but pollution control equipment mandated in recent decades now require that it be captured prior to release. In the US, fly ash is generally stored at coal power plants or placed in landfills. About 43 percent is recycled, often used to supplement Portland cement in concrete production. It is increasingly finding use in the synthesis of geopolymers and zeolites.

This book documents CCPS's Aerosol Research Program to develop a model to predict liquid rainout from release of a pressurized, liquefied gas--and, hence the residual amount of material in a vapor cloud, which may be greater than the amount calculated from an enthalpy chart. RELEASE predicts the rate of fluid discharge, the depressurization, flashing and formation of liquid drops, the entrainment of drops into the vapor cloud, the subsequent spreading of the jet, and rate of liquid rainout to a pool on the ground. Designed in a modular fashion to permit adjustment and corrections as new data become available, its multi-layered approach contains sub-models that include the complexities of many variables, including the effect of liquid superheat, rate of bubble growth, criterion for bubble formation, and heat transfer from the liquid to the growing vapor bubble. To validate RELEASE, CCPS conducted small- and large-scale experiments using superheated water, heated liquefied chlorine, methylamine, and cyclohexane that produced valuable data in an area where data are scarce. This book gives complete access, in text and on CD-ROM, to the model and the test data, giving users an informed ability to apply the model to their own work.

Interest in solid and hazardous waste management is relatively recent, i.e., in the last three decades, and is driven by regulations in most countries. It began with industrial hazardous waste followed by municipal solid waste, and subsequently by many other categories of waste. This book presents numerous examples and case studies of innovative tools, treatment methods and applications in this growing area of research and development. It describes in detail laboratory methods of measuring the biodegradation of specific organic fractions, like floral waste, and also discusses the treatment of yard and food waste by anaerobic digestion and landfill leachate using constructed wetlands. Case studies are provided that show how remote sensing (RS) and GIS were used to develop an integrated solid waste management plan for a city and to evaluate the environmental impacts of stone quarrying activities. The book also features chapters discussing the implications of natural radioactivity in beach placers and their impact on groundwater and other parts of the environment, as well as the twelve principles of green chemistry and their application in the reuse and recycling of solid waste. Moreover, it includes examples of waste to energy, like refuse derived fuel and biofuel generation and an evaluation of their potential, and covers topics such as life cycle assessment as a tool for developing integrated solid waste management systems and an overview of municipal solid waste management rules, illustrating the importance of technological inputs in the development of regulatory frameworks. Written by leading practitioners and scholars in the field, the book enables readers to understand and apply these principles and practices in their endeavours.

While innovative technologies in remediation need to be developed, so do innovative ways of site assessment. This monograph describes the development, testing, and performance of a new laser-induced fluorescence soil probe. A screening tool for site characterization, this probe has the potential to provide an economical, rapid assessment of contaminated sites. Cone Penetrometer testing equipment advances the probe into the subsurface. The probe identifies hydrocarbon classes using a multi-channel excitation-emission matrix. This technique facilitates the collection of significant amounts of subsurface information - surpassing conventional data collection methods - that can be used to rapidly identify areas of concern beneath a site. The technology has significant application for the following: Rapid environmental site assessment Monitoring remediation programs Monitoring manufacturing processes and industrial waste water operations Subsurface Contamination Monitoring Using Laser Fluorescence provides comprehensive reference material for researchers and engineers as well as engineering consultants interested in subsurface monitoring techniques or further development of this technology. It describes innovative technology that focuses on finding cost effective solutions for site assessment and remediation.

Biotechnology in Industrial Waste Treatment and Bioremediation addresses the increasingly important topic of waste treatment. Focusing on microbiological degradation of contaminants, it offers a representative picture of the current status of environmental biotechnology and lays a solid foundation of the methods and applications of bioremediation. The expert presentations of case studies in this new book demonstrate successful treatment schemes and technologies meeting regulatory standards. These case studies represent an international cross-section of strategies for developing and implementing the evolving technologies of bioremediation. Biotechnology in Industrial Waste Treatment and Bioremediation examines the primary waste streams, including air, water, soils, and sediments, and explores specific treatment methodologies for industrial and environmental contaminants. This broad and unique coverage allows treatment firms and regulatory authorities to determine and develop appropriate treatment strategies for site-specific problems of waste remediation. The observations and successful field applications compiled in Biotechnology in Industrial Waste Treatment and Bioremediation make it an excellent reference for understanding, evaluating, developing, and operating efficient and cost-effective full-scale treatment systems.

This book presents an integrated approach to understanding environmental contamination problems through the use of techniques from environmental chemistry, toxicology, ecology, and ecotoxicology. Basing much of his information on his 21 years of experience in the field, the author proposes innovative strategies for studying the environmental fate of contaminants, evaluating the effects, and producing scientific criteria for environmental safety. The book is clearly written, with all terms defined and equations explained with examples of their application. Weak points in the present knowledge are pointed out and discussed. An extensive list of references is provided for individuals who wish to delve deeper into the subject.

An increasing portion of the world's population and economic activity is located on lands adjacent to coastal waters. The result is ever increasing demands on the coastal resources, leading to increasing conflicts among uses and users and to decreased capacity of the resources to provide desired products and services. The study team carried out three analytical tasks. The first was to trace explicitly the evolution of the mix of uses of the bay over time, and the factors responsible therefore. The second was to analyze alternative futures to shed light on the net benefits to society of alternative management strategies. The third was to analyze existing institutional arrangements for decision-making for the Bay.
Topics: Context and foci of study; Disposal of solid wastes; Living marine resources; Marine transport; Disposal of liquid wastes; Water-based recreation; Formulationn of the analysis; Estimating benefits implications for management to Tokyo Bay.

Catalytic Air Pollution Control: Commercial Technology is the primary source for commercial catalytic air pollution control technology, offering engineers a comprehensive account of all modern catalytic technology. This Third Edition covers all the new advances in technology in automotive catalyst control technology, diesel engine catalyst control technology, small engine catalyst control technology, and alternate sustainable fuels for auto and diesel.

The completion of the initial phase of the U.S. National Acid Precipitation Assessment Program (NAPAP) in 1990 marked the end of the largest environmental research and assessment effort to that time. The resulting series of 27 State of Science and Technology (SOS/T) Reports and the NAPAP Integrated Assessment represent a decade of work by hundreds of scientists, engineers, and economists. Since then, many new, significant, more refined studies on acid deposition have been completed and published, considerably broadening knowledge in this area.

Aquatic Effects of Acidic Deposition summarizes and synthesizes these major advancements, particularly those topics that are directly relevant to policy making. It offers complete coverage of recent findings that have substantiated, deepened, modified, or in some cases, revolutionized scientific understanding in environmental research.

This resource addresses the quantification of effects and recent developments in predictive modeling capabilities. It covers virtually all aspects of nitrogen effects research, the importance of natural sources of acidity, the influence of land use and landscape change on drainage water chemistry, and the role of short-term episodic events.

This comprehensive update thoroughly illustrates the progression and refinement in the field. Aquatic Effects of Acidic Deposition helps you make educated decisions based on the most recent, reliable data for air pollution sensitivities, effects, remediation, and future research.

Engineering and science professionals have studied the management of hazardous and toxic wastes extensively, and it is clear that the principal option of the future will be waste minimization, or pollution prevention. At present, however, few practicing professionals have a working understanding of this approach, educators are just starting to teach course material in this field, and students are only beginning to receive the training necessary to implement pollution prevention in their future work environment. An applications-oriented workbook of more than 100 exercises, Pollution Prevention: Problems and Solutions covers a variety of topics closely relevant to this field. The workbook is the result of a National Science Foundation College Faculty Workshop designed to generate new ideas and innovative educative approaches in the emerging, interdisciplinary field of pollution prevention. Contents include a pollution prevention overview in addition to problems and solutions organized into the categories of basic concepts, pollution prevention principles, regulations, source reduction, recycling, treatment, chemical plant/domestic applications, case studies, and ethics.

Peril in the Ponds tells the story of a government biologist's investigation into the mystery of deformed frogs, an epidemic that grew during the 1990s and continues today. It provides an inside view of a highly charged environmental issue that aroused the public and the media and sparked controversies among scientists, politicians, and government agencies. By the 1990s, wetlands across the United States were endangered from pollution and decades of drainage to convert them into farmland and urban developments. But when deformed frogs, many with missing legs or eyes, footless stumps, or misshapen jaws, began to emerge from Minnesota wetlands, alarm bells went off. What caused such deformities? Pollution? Ultraviolet rays? Biological agents? And could the mysterious cause also pose a threat to humans? Judy Helgen writes with passionate concern about vulnerable frogs and wetlands as she navigates through a maze of inquisitive media and a reluctant government agency. She reports on the complexity of a growing catastrophe for frogs and broadens the issue as she researches and meets with scientists from around the world. She affirms the importance of examining aquatic life to understand pollution and the need to rescue our remaining wetlands. She also shares the fears expressed by the teachers, students, and other citizens who found these creatures, sensed a problem, and looked to her for answers. Ultimately, this is a story about the biological beauty of wetlands and our need to pay attention to the environment around us.
