Available in PDF, EPUB and Kindle. Book excerpt: They are the first maps of total deposition for all major ions in precipitation for Manitoba and Saskatchewan; further, they are consistent with the annual average wet and dry deposition fields (1994-1998) recently developed for eastern Canada and used in the eastern Canada critical load assessment. [...] Shortly after the initiation of the project, Environment Canada (EC) agreed to generate total deposition fields for Manitoba and Saskatchewan consistent with the fields recently developed for eastern Canada and used in the eastern Canada critical load assessment (Environment Canada 2004). [...] This final report incorporates the interim report which assessed the availability and quality of data required for the determination and mapping of critical loads for Manitoba and Saskatchewan. [...] For example, a standard level I mass balance approach for acidity of forest soil would identify the sources of acidity and alkalinity in the system and determine the maximum acid input that will balance the system at a specified critical limit for the selected chemical criterion (see Section 3.2). [...] The model inputs required for the determination of critical loads of S and N for upland forests in Manitoba and Saskatchewan are described in detail in the following sections.

Download or read book Approaches for Estimating Critical Loads of Nitrogen and Sulfur Deposition for Forest Ecosystems on U S Federal Lands written by Linda H. Pardo and published by . This book was released on 2010 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Critical Loads and Dynamic Risk Assessments written by Wim de Vries and published by Springer. This book was released on 2015-04-20 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Acidic Deposition and Forest Soils written by Dan Binkley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge in the field of acidic deposition is expanding rapidly, and both ex perts and non-experts are challenged to keep up with the latest information. We designed our assessment to include both the basic foundation needed by non experts and the detailed information needed by experts. Our assessment in cludes background information on acidic deposition (Chapter 1), an in-depth discussion of the nature of soil acidity and ecosystem H+ budgets (Chapter 2), and a summary of rates of deposition in the Southeastern U.S. (Chapter 3). A discussion of the nature of forest soils in the region (Chapter 4) is followed by an overview of previous assessments of soil sensitivity to acidification (Chapter 5). The potential impacts of acidic deposition on forest nutrition are described in the context of the degree of current nutrient limitation on forest productivity (Chap ter 6). The results of simulations with the MAGIC model provided evaluations of the likely sensitivity of a variety of soils representative of forest soils in the South (Chapter 7), as well as a test of soil sensitivity criteria. Our synthesis and recommendations for research (Chapter 8) also serve as an executive summary. A complementary volume in the Springer-Verlag Ecological Studies series should be consulted for information on European forests. This volume, Acidic Deposition and Forest Decline in the Fictelgebirge, edited by E.-D. Schultze and O.L. Lange, also provides greater detail on the physiologic responses of trees than we present in our regional assessment.
Download or read book Acid Rain Deposition to Recovery written by Peter Brimblecombe and published by Springer Science & Business Media. This book was released on 2007-12-11 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
