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.

These articles discuss aerobic and anaerobic biological degradation for dehalogenating sites contaminated with pesticides and chlorinated solvents. Bench-and field-scale studies are described, as are microcosm studies, numerical simulations, and site characteristics and their effect on the stability of methanotrophic community. Methods discussed include air venting, alternative electron donors, biofilm reactors, surfactants, municipal digester sludge, iron enhancement, and sulfate reduction to improve conditions for microbial consortia.
