Book Description
Acid deposition is considered to be one of the greatest threats to the environment in industrialised countries. Recognising this , governments have instituted programmes to reduce emissions of SO2, and NOx, the major sources of acid rain. But is this enough? Will ecosystems damaged by acid rain recover? And if they do, how quickly? What ecosystem processes determine the rate of recovery? Do acidification models give accurate predictions? Are any other actions necessary to promote recovery? To answer such questions without waiting for the results of current policies, scientists in Sweden and the UK decided to eliminate acid deposition on an acidified ecosystem altogether, and monitor the effects. They did this by constructing a huge roof over an acidified catchment near Lake Gårdsjön in Southwest Sweden. Acid rain falling on the roof is diverted away, and replaced with clean rain. The detailed responses of the ecosystem are measured. This book records the results from the first five years of the Project, and considers the implications for emission control. The book describes the effect of eliminating acid deposition (and some other pollutants) on vital ecosystem processes ? both chemical and biological ? and how the predictions of acidification and hydrological models compared with experimental results. It describes the covered catchment, how the roof was constructed and the problems associated with such large experiments. The implications for pollution control policies, and what still needs to be discovered, are emphasised. The book should be of interest to a wide variety of environmental scientists, especially those interested in pollution effects, forestry, freshwater fisheries, and ecosystem function, and to environmental managers and policymakers.

Book Description
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

Book Description
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Book Description
Ecosystem effects from air pollution in the Adirondacks, Catskills, and elsewhere in New York have been substantial. Efforts to characterize and quantify these impacts, and to examine more recent recovery, have focused largely on surface waters, soils, and forests. Lakes, streams, and soils have acidified. Estuaries have become more eutrophic. Nutrient cycles have been disrupted. Mercury has bioaccumulated to toxic levels. Plant species composition has changed. Some surface waters show signs of partial chemical recovery in response to emissions control programs, but available data suggest that soil chemistry may continue to deteriorate under expected future emissions and deposition. Resource managers, policymakers, and scientists now need to know the extent to which current and projected future emissions reductions will lead to ecosystem recovery.In this book, Timothy J. Sullivan provides a comprehensive synthesis of past, current, and potential future conditions regarding atmospheric sulfur, nitrogen oxides, ammonium, and mercury deposition; surface water chemistry; soil chemistry; forests; and aquatic biota in New York, providing much needed information to help set emissions reduction goals, evaluate incremental improvements, conduct cost/benefit analyses, and prioritize research needs. He draws upon a wealth of research conducted over the past thirty years that has categorized, quantified, and advanced understanding of ecosystem processes related to atmospheric deposition of strong acids, nutrients, and mercury and associated ecosystem effects. An important component of this volume is the new interest in the management and mitigation of ecosystem damage from air pollution stress, which builds on the "critical loads" approach pioneered in Europe and now gaining interest in the United States.This book will inform scientists, resource managers, and policy analysts regarding the state of scientific knowledge on these complex topics and their policy relevance and will help to guide public policy assessment work in New York, the Northeast, and nationally.

Book Description
This book provides an up-to-date synthesis of the understanding of the interaction between the emission of nitrogen, its deposition and impact on the most important components of natural and semi-natural ecosystems. The work consists of contributions from internationally renowned research scientists. Individual chapters deal with the factors and processes related to nitrogen deposition and soils, non-forest vegetation communities, forest ecosystems, and surface waters. The assessment of these impacts is discussed in terms of setting critical loads. The book is aimed at researchers, advanced course students and policy makers/advisors involved with aspects of the impact of air pollution.

Aiken, South Carolina Domy C. Adriano Coordinating Editor Preface to Acidic Precipitation, Volume 5 (Advances in Environmental Science) Acidification research has been ongoing for several decades. It was not until the 1980s, however, that scientists began to recognize the complex ity of the factors causing the decline in forest growth and deterioration of fish populations in acidified lakes. The general feeling, based on correla tive research, was that long-range transported air pollution was the main cause. Proof, however, was difficult to obtain because of complex interac tions of various stress factors including natural ones.
