Book The 1990 Canadian Long range Transport of Air Pollutants and Acid Deposition Assessment Report Part 4

Download or read book The 1990 Canadian Long range Transport of Air Pollutants and Acid Deposition Assessment Report Part 4 written by and published by . This book was released on 1990 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1990 assessment of aquatic effects related to the long range transport of atmospheric pollutants provides a summary of the present and predicted future status of Canadian aquatic ecosystems in relation to development of government policy on acidic deposition. The policy orientation of the report is reflected particularly in an evaluation of critical SO2 loads for sub-regions of eastern Canada which required specification of a biologically relevant threshold criterion for pH. The report reviews the current state of the Canadian aquatic ecosystem and evaluates the effect of SO2 deposition on lakes using water chemistry models leading to specification of critical and target loadings. Models are also used to forecast the future condition of Canadian lakes based on 4 realistic SO2 emission control scenarios. The rate of deterioration or recovery is also discussed and an evaluation of receptor migration (lake and stream liming) is presented.

Book The 1990 Canadian Long range Transport of Air Pollutants and Acid Deposition Assessment Report Part 5

Download or read book The 1990 Canadian Long range Transport of Air Pollutants and Acid Deposition Assessment Report Part 5 written by and published by . This book was released on 1990 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Canadian assessment document reviews the past 4 years of scientific effort to provide a basis for future decisions on continued research, monitoring, and control strategies and to facilitate evaluation of the efficacy of Canadian and international abatement programs. The 1990 assessment dealt with the levels of acidic wet deposition, ozone and associated pollutants that can be tolerated without significantly affecting the terrestrial environment; the improvements due to Canadian and/or US emission reduction scenarios which can be expected; and the risk of acidic wet deposition, ozone and associated pollutants changing the forest, causing hardwood decline, reducing agricultural production, and affecting terrestrial wildlife. An overview is also given of the monitoring systems in place, including surveys, soil sensitive mapping, remote sensing, early diagnosis, and biomonitoring.

Book The 1990 Canadian Long range Transport of Air Pollutants and Acid Deposition Assessment Report Part 8

Download or read book The 1990 Canadian Long range Transport of Air Pollutants and Acid Deposition Assessment Report Part 8 written by J. Lawrence and published by . This book was released on 1990 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1982, a memorandum of intent was jointly developed by the US and Canada to address the issue of the long range transport of air pollutants. The question of acid loadings to both countries was addressed and it was noted that information provided by the two countries differed significantly and that there were questions as to the reliability of various data collected prior to 1980. A subcommittee was established to address and promote quality assurance goals for every study in the LRTAP program. This report describes the history, accomplishments and short-comings in the quality assurance programs for aquatic, atmospheric and terrestrial studies as well as those conducted in the laboratory.

Download or read book The 1990 Canadian Long range Transport of Air Pollutants and Acid Deposition Assessment Report Part 3 written by and published by . This book was released on 1990 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air and precipitation monitoring programs have been in place in Canada since the early 1980s, and have by now yielded a substantial, high-quality data set. This report examines various approaches to evaluating source-receptor relationships (i.e., the quantitative relationships between current and future emissions, and receptor exposure) in North America and particularly in Canada. The report examines the variation in acid gas emissions in eastern North America, identifies some significant changes that have occurred since 1980 in Canada and the adjoining States, and examines the response of deposition spatial patterns, as well as air and precipitation concentrations in eastern Canada, to these changes. The current understanding about the capability of the available models to predict source-receptor relationships is examined, with the findings of a preliminary Eulerian model included.

Book Acidification Research Evaluation and Policy Applications

Download or read book Acidification Research Evaluation and Policy Applications written by T. Schneider and published by Elsevier. This book was released on 1992-04-24 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large number of nationwide research programmes in the field of acidification have been carried out in the last decade. Especially in Western Europe, extensive programmes have resulted in a good overview of all the effects - mostly negative - caused by acidifying substances. There is now consensus that types of acidification damage relate to the unique geography of an area: air pollution affects vegetation; acid aerosol the ozone layer. New in this volume, is the relation between scientific results of integrated research programmes and policy actions to prevent, reduce and limit the widespread damage caused by acidification. The results of many different national research programmes are evaluated and compared to present a unique compilation for the research scientist and policy maker. In this volume thematic reviews on specific topics of acidification research are presented, followed by overviews of acidification policy plans and actual abatement plans. The result is the best review of acidification research carried out worldwide during the last decade and presentation of the critical relation between research results and policy actions.
