'Acid rain' is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. Wet deposition refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals. The strength of the effects depends on many factors, including how acidic the water is, the chemistry and buffering capacity of the soils involved, and the types of fish, trees, and other living things that rely on the water. Dry deposition refers to acidic gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition. The wind blows these acidic particles and gases onto buildings, cars, homes, and trees. Dry deposited gases and particles can also be washed from trees and other surfaces by rainstorms. When that happens, the runoff water adds those acids to the acid rain, making the combination more acidic than the falling rain alone. Prevailing winds blow the compounds that cause both wet and dry acid deposition across state and national borders, and sometimes over hundreds of miles. This new book combines an excellent background article with over 900 abstracts and book citations. Easy access is provided by title, author, and subject indexes.

This is a compilation of topics that are at the forefront of many technical advances and practices in air and water control. These include air pollution control, water pollution control, water treatment, wastewater treatment, industrial waste treatment and small scale wastewater treatment.

This book presents the latest scientific information and analysis concerning the costs, benefits, and environmental effectiveness of the Acid Rain Program (ARP), a bipartisan mandate under Title IV of the 1990 Clean Air Act Amendments signed into law by President George H W Bush to reduce sulphur dioxide (SO2) and nitrogen oxides (NOx) emissions from electric generating sources. Notably, the SO2 program includes the use of a creative emissions cap-and-trade program that combines the best of American science, government, and market-driven innovation. This book focuses on emission reductions from power plants, summarises changes in deposition rates and environmental impacts, and evaluates the ecological effects expected to accompany future reduction in SO2 and NOx emissions.

This book, first published in 1984, examines the process of building suitable collections for sci-tech libraries. Sci-tech collections are not the easiest to develop successfully in view of the complexity of the subjects involved, the large number of choices to make, and the difficulty of even knowing about certain grey area publications, such as meetings proceedings, government documents and technical reports. Expert writers assess these difficulties and provide a guide to solutions to the problems inherent in building these collections.
