Acid Rain Control

'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 volume, Proceedings of the Conference ACID RAIN: Economic Assessment, is meant to present the areas of agreement which economists have established and the uncertainties which they have discovered in their attempts to use the methodology of economics to better understand the nature of the acid rain issue. Scientific articles about acid rain initially appeared in 1972. The public turned its attention to the issue in the mid-1970s. In April 1979, the first acid rain bill was introduced in the Senate, authored by New York's Senator Daniel P. Moynihan. The bill sought to establish a federal research program dedicated to filling the gaps in understanding of the phenomena of long-range transport of air pollutants and their environmental, health and economic impacts. 'The bill was passed into law in 1980. Since then, tens of bills have been proposed to control emissions of S02 and NO , x thought to be the precursors of acid rain. And yet, in contrast with the pattern set by the majority of environmental issues, where legislation followed very quickly on the heels of public anxiety and involvement, by July 1985 not a single federal acid rain control bill had been passed.

This collection of essays by noted academicians, lawyers, energy agency administrators, and research analysts focuses on the political and legal aspects of the acid rain debate, the policy options for resolving the controversy, and the international dimensions of acid rain control. The contributors highlight concerns drawn primarily from the developing study of acid rain in political science, economics, public administration, and policy analysis--concerns that are the focal point of the public debate over the nature, impact, and cost of acid rain and the mitigation of its effects. The book complements the impressive body of research from the natural sciences and responds to the need for applied study to help resolve the current policy stalemate on this critical environmental issue. The Acid Rain Debate features a comprehensive annotated bibliography on acid rain and relevant social science research.

Acomprehensive review of the state-of-the-art research, development, and commercialization potential of tech­nology in acid rain control. These papers by noted researchers, con­sultants, and program directors in the acid rain and energy field were delivered at a conference sponsored by the Illinois General Assembly and the Coal Extraction and Utilization Research Center at South­ern Illinois University, Carbondale. The book begins with a good tech­nological overview of the problem and possible solutions. Major points of inter­est are the roles of advanced coal cleaning technologies, flue-gas desulfurization (FGD), limestone injection multiphase burners (LIMB), fluidized-bed com­bustors (FBC), integrated combined-cycle systems, coal gasification, coal switching or compliance coal, and the use of nuclear energy in the control of acid deposition. Diane Suitt Gilleland and James H. Swisher also edited the previous con­ference proceedings, Acid Rain Control: The Costs of Compliance (Southern Illi­nois University Press).
