Canadian Acid Deposition Science Assessment, 2004


Book Description

"The 2004 Canadian Acid Deposition Science Assessment has been prepared by researchers from the federal and provincial governments and academia. This assessment builds upon the results presented in the 1997 Canadian Acid Rain Assessment. The assessment consists of two documents, the Summary of Key Results and the Assessment. The Summary of Key Results synthesizes the major findings of the Assessment in the context of ten questions and subquestions put forth by the acid deposition policy and science communities. The Assessment presents a comprehensive review of acid deposition science in Canada."--Environment Canada Website.







Critical Loads and Dynamic Risk Assessments


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.




Air Pollution Modeling and Its Application XVII


Book Description

This volume seeks to cover the latest scientific developments in the field of air pollution modelling. It contains papers and posters presented at the Proceedings of the Twenty-Seventh NATO/CCMS International Technical Meeting on Air Pollution Modelling and Its Application, November 2004.







Insulators for Icing and Polluted Environments


Book Description

Learn to correct icing and pollution problems in electrical line insulation Written by prominent experts in the field, this book takes an in-depth look at the issues of electrical insulators for icing and polluted environments. It shows: Engineers and environmental specialists how to carry out appropriate insulator contamination measurements, understand how these readings change with time and weather, and work out how the readings compare with the upper limits set by insulator dimensions in their existing stations Design engineers how to assess the likely maximum pollution and icing limits at a substation or along an overhead line, and then select insulators that have appropriate withstand margins Regulators why modest ice accretion at a moderate 0oC temperature on one occasion can qualify as a major reliability event day, while many similar days pass each winter without power system problems Educators why the ice surface flashover is well behaved compared to the conventional pollution flashover, making it much more suitable for demonstrations, modeling, and analysis The book is complemented with case studies and design equations to help readers identify the most appropriate insulators, bushings, and maintenance plans for their local conditions. Additionally, readers may download supplemental materials supporting evaluation of local climate and contamination. Insulators for Icing and Polluted Environments is indispensable reading for any professional who needs reliable electrical supply from networks exposed to sources of wetting and pollution. It also serves as an excellent introduction to the subjects of high-voltage surface flashover, environmental electrochemistry, and insulation coordination for researchers, professors, and students.




Air Quality Management


Book Description

This book provides a wide overview of the issues related to managing of air quality in Canada. Learn about the air issues that have caused impacts to ecosystems or human health and hence been targeted to be managed. Discover how Canada’s national governance involving a federal government along with provincial and territorial governments impacts the air quality management process. Understand how Canadians manage their air quality in context with the USA, their largest and closest neighbour. Benefit from the experience of 43 of Canada’s most experienced air quality management professionals who share their insights into the state of air quality in Canada today, how it is managed, as well as giving a glimpse into the future.​







The Diatoms


Book Description

This much revised and expanded edition provides a valuable and detailed summary of the many uses of diatoms in a wide range of applications in the environmental and earth sciences. Particular emphasis is placed on the use of diatoms in analysing ecological problems related to climate change, acidification, eutrophication, and other pollution issues. The chapters are divided into sections for easy reference, with separate sections covering indicators in different aquatic environments. A final section explores diatom use in other fields of study such as forensics, oil and gas exploration, nanotechnology, and archaeology. Sixteen new chapters have been added since the first edition, including introductory chapters on diatom biology and the numerical approaches used by diatomists. The extensive glossary has also been expanded and now includes over 1,000 detailed entries, which will help non-specialists to use the book effectively.




Technical Challenges of Multipollutant Air Quality Management


Book Description

Recent critiques of air quality management approaches currently employed in developed and many developing countries have suggested that efficiencies could be achieved if air quality management practices shifted from pollutant-by-pollutant approaches to a comprehensive multipollutant approach in which emission reduction decisions are based on relative risk and evaluated on their effectiveness in meeting environmental and health goals. This book assesses our technical readiness to undertake such an approach, and it outlines the technical developments that will be needed to achieve a risk-based approach air quality management that includes means for measuring the effectiveness of management decisions.
