Book Description
Projected emissions of sulfur and nitrogen are expected to have continuing negative impacts on forests, in spite of reductions in sulfur emissions as a result of SO2 control programs. Sulfur and nitrogen emissions present serious long-term threats to forest health and productivity in the United States. This report is intended to explain the differences in approaches for calculating critical loads for forest ecosystems in Europe, Canada, and the United States; it is directed to air quality regulators and Federal Land Managers (FLMs) in the United States, and addresses concerns particular to U.S. Federal lands. The paper describes the basic mass balance approach for calculating critical loads, presents the various critical thresholds, and explains the assumptions inherent in the calculation and data selection procedure. The input necessary from FLMs in the process of estimating the critical load is described.

Critical Loads and Dynamic Risk Assessments
Author: Wim de Vries
Publisher: Springer
ISBN: 9401795088
Category : Science
Languages : en
Pages : 671
Book Description
This book provides a unique overview of research methods over the past 25 years assessing critical loads and temporal effects of the deposition of air pollutants. It includes critical load methods and applications addressing acidification, eutrophication and heavy metal pollution of terrestrial and aquatic ecosystems. Applications include examples for each air pollution threat, both at local and regional scale, including Europe, Asia, Canada and the US. The book starts with background information on the effects of the deposition of sulphur, nitrogen and heavy metals and geochemical and biological indicators for risk assessments. The use of those indicators is then illustrated in the assessment of critical loads and their exceedances and in the temporal assessment of air pollution risks. It also includes the most recent developments of assessing critical loads and current and future risks of soil and water chemistry and biodiversity under climate change, with a special focus on nitrogen. The book thus provides a complete overview of the knowledge that is currently used for the scientific support of policies in the field of air pollution control to protect ecosystem services.
