The causes and consequences of acid rain are subjects of widespread concern and controversy. However the effects of acid deposition on the chemistry of lakes and streams, and on the survival of fish and other aquatic life, have been greatly clarified by the results of a recent Anglo-Scandinavian surface waters research program. This book presents a concise, nonspecialist account of the results and their implications by the director of the program. Based on studies conducted throughout the United Kingdom and northern Europe, the book includes chapters on emissions, transport, and deposition of acid pollution; hydrochemical studies in catchments; catchment process studies; catchment manipulation experiments; the role of hydrology and soil chemistry; palaeolimnological studies; the toxic effects of acidification on fish and other aquatic life; and catchment modelling studies. The highly interdisciplinary nature of the research should appeal to a wide range of scientists and to policy-makers interested in acid rain and its consequences. It is also aimed at postgraduates and third-year undergraduate students in the environmental sciences.
'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.
Presents an overview of the normal functioning of terrestrial ecosystems and up-to-date documentation on the effects of acid precipitation.
Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.
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.
The book analyzes the behavior and performance of the market for emissions permits, called allowances in the Acid Rain Program, and quantifies emission reductions, compliance costs, and cost savings associated with the trading program."--BOOK JACKET.

This book looks at the sources and composition of the atmosphere and rainfall, with particular attention on acidifying components and those that affect ecosystems. It further widens the subject to look at trace metals. It includes papers on the impact of deposition on soils and forests and the recovery of the natural environment. Work on critical loads makes a contribution to understanding the degree to which deposition must be reduced to limit its impact.
