This book was released on 2019-06-27 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book integrates 30 years of mercury research on the Florida Everglades to inform scientists and policy makers. The Everglades is an iconic ecosystem by virtue of its expanse; diversity of biota; and multiple international designations. Despite this, the Everglades has been subjected to multiple threats including: habitat loss, hydrologic alterations, invasive species; and altered water quality. Less well recognized as a threat to Everglades human use and wildlife populations is the toxic metal, mercury. This Volume focuses on sources of mercury to the Everglades from the late-1980’s when there was bewilderment as to why there were very high levels of mercury in the Everglades food web. Soon came the finding that mercury loadings from atmospheric deposition accounted for over 95% of total input to the Everglades which resulted in Florida conducting the most comprehensive mercury monitoring and modeling study performed to date. Topics discussed in this Volume include: (1) Why atmospheric deposition fluxes of mercury to the Everglades are amongst the highest in the U.S; (2) That these are overwhelmingly from sources outside of the U.S; (3) That mitigation strategies for resolving the elevated food web mercury problem in the Everglades that rely solely on reducing atmospheric mercury inputs will not be effective for many decades; (4) That consideration of other strategies, in particular controlling factors related to Everglades mercury biogeochemical cycling seem warranted.

Download or read book Alberta Oil Sands written by and published by Newnes. This book was released on 2012-11-07 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: At 170 billion barrels, Canada's Oil Sands are the third largest reserves of developable oil in the world. The Oil Sands now produce about 1.6 million barrels per day, with production expected to double by 2025 to about 3.7 million barrels per day. The Athabasca Oil Sands Region (AOSR) in northeastern Alberta is the largest of the three oil sands deposits. Bitumen in the oil sands is recovered through one of two primary methods – mining and drilling. About 20 per cent of the reserves are close to the surface and can be mined using large shovels and trucks. Of concern are the effects of the industrial development on the environment. Both human-made and natural sources emit oxides of sulphur and nitrogen, trace elements and persistent organic compounds. Of additional concern are ground level ozone and greenhouse gases. Because of the requirement on operators to comply with the air quality regulatory policies, and to address public concerns, the not-for-profit, multi-stakeholder Wood Buffalo Environmental Association (WBEA) has since 1997 been closely monitoring air quality in AOSR. In 2008, WBEA assembled a distinguished group of international scientists who have been conducting measurements and practical research on various aspects of air emissions and their potential effects on terrestrial receptors. This book is a synthesis of the concepts and results of those on-going studies. It contains 19 chapters ranging from a global perspective of energy production, measurement methodologies and behavior of various air pollutants during fossil fuel production in a boreal forest ecosystem, towards designing and deploying a multi-disciplinary, proactive, and long-term environmental monitoring system that will also meet regulatory expectations. - Covers measurement of emissions from very large industrial sources in a region with huge international media profile - Validation of measurement technologies can be applied globally - The new approaches to ecological monitoring described can be applied in other forested regions
Download or read book Receptor Modeling for Air Quality Management written by P.K. Hopke and published by Elsevier. This book was released on 1991-06-03 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the background and application of receptor models for the source identification and quantitative mass apportionment of airborne pollutants. Over the past decade, receptor models have become an accepted part of the process for developing effective and efficient air quality management plans. Information is provided on the ambient and source sampling and chemical analysis needed to provide the input data for receptor models. Commonly used models are described with examples so that the air quality specialist can see how these models are applied. Recent advances in several areas of the field are presented as well as the perspective of both U.S. Federal and State level air quality managers on how these models fit into the development of a management plan.The aim of the book is to provide a practical guide to persons who may be given the task of implementing receptor modeling as a part of some air quality management problem. The intention of all the chapter authors is to furnish both the basic information needed to begin doing receptor modeling as well as some insight into some of the problems related to the use of these models. These tools like any others used in solving complex technological problems are not a panacea, but do represent powerful aids in data analysis that can lead to insights as to how an airshed functions and thus, to effective and efficient air quality management strategies.

Download or read book Air Quality and Ecological Impacts written by Allan H. Legge and published by Elsevier. This book was released on 2009-04-01 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Quality and Ecological Impacts reviews the characterization of air quality as it pertains to specific emission sources and their environmental effect. Since emissions from multiple sources impact the same location, a multidisciplinary approach is needed to relate atmospheric processes to terrestrial vegetation. As global industrial expansions continue, air quality is no longer governed by isolated point sources (e.g., a single coal-fired power plant), but by source clusters or complexes. To address these issues, atmospheric receptor models have been developed and are continually being improved. The benefits of any air quality control measures based on receptor modeling must be verified by assessing changes or bettering in environmental impacts. Until now, such an approach has not been well integrated and practiced. This book provides the needed concepts and methods in conducting the studies to establish cause-and-effect relationships under ambient conditions, which is valuable to policy makers both in industrialized and developing nations. - Offers approaches for identifying the emissions components from specific air pollution sources - Details methods for using pollutant accumulation in plants for ecological effects assessment - Establishes cause (air quality) and effect (plant responses) relationships under ambient conditions

Download or read book The Geographical Sciences During 1986 2015 written by Shuying Leng and published by Springer. This book was released on 2016-07-28 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: In four chapters and an introduction, this book systematically helps readers understand the development of the Geographical Sciences both in China and in the world during the past 30 years. Through data analysis of methodologies including CiteSpace, TDA, qualitative analysis, questionnaires, data mining and mathematical statistics, the book explains the evolution of research topics and their driving factors in the Geographical Sciences and its four branches, namely Physical Geography, Human Geography, Geographical Information Science and Environmental Geography. It also identifies the role of the Geographical Sciences in the analysis of strategic issues such as global change and terrestrial ecosystems, terrestrial water cycle and water resources, land change, global cryosphere evolution and land surface processes on the Tibetan Plateau, economic globalization and local responses, regional sustainable development, remote sensing modelling and parameter inversion, spatial analysis and simulation, and tempo-spatial processes and modelling of environmental pollutants. It then discusses research development and inadequacy of Chinese Geographical Sciences in the above-mentioned topics, as well as in the fields including Geomorphology and Quaternary environmental change, Ecohydrology, ecosystem services, the urbanization process and mechanism, medical and health geography, international rivers and transboundary environment and resources, detection and attribution of changes in land surface sensitive components, and uncertainty of spatial information and spatial analysis. It shows that the NSFC has driven the development in all these topics and fields. In addition, the book summarises trends of the Geographical Sciences in China and the research level in major countries of the world through an overview of geographical education in colleges and universities, the analysis of publications, citations and author networks of SCI/SSCI and CSCD indexed articles, and the description of Sino-USA, Sino-UK and Sino-German cooperation. This book serves as an important reference to anyone interested in geographical sciences and related fields.

This book was released on 2011-07-30 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
