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 Nitrogen Deposition Critical Loads and Biodiversity written by Mark A. Sutton and published by Springer Science & Business Media. This book was released on 2014-04-10 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together extended reviews and papers of new scientific research on atmospheric nitrogen deposition impacts globally. While there is a wealth of evidence on the magnitude, components and effects of nitrogen disposition on floral biodiversity in Europe and North America, there is an obvious lack of information on impacts on above- and below-ground fauna, and all impacts in other parts of the world, with no clear overview of how the different strands of evidence fit together. This overall synthesis is targeted at the international conventions, but is equally readable for scientists, environmental managers, conservation agencies and policy makers. 'This timely book highlights the global nitrogen deposition problem. Major regions of the world are exceeding sustainability thresholds for adverse effects on ecosystem function and biodiversity. This highlights the importance of ongoing work, including under the Convention on Biological Diversity, in developing indicators and monitoring nitrogen deposition effects to enable appropriate measures. This book presents a milestone towards this global goal as the international community works toward meeting the Aichi Biodiversity Targets, especially Target 8: "By 2020, pollution, including from excess nutrients, has been brought to levels that are not detrimental to ecosystem function and biodiversity". Braulio Ferreira de Souza Dias, Executive Secretary, Convention on Biological Diversity “This key volume highlights the global challenge to reduce atmospheric nitrogen pollution resulting from energy production, transport and agricultural activities. It takes forward the agenda recently launched in the UNEP commissioned report ‘Our Nutrient World”. Dr. Anjan Datta, UNEP.

Book excerpt: Ecotoxicology offers an overview of current ecotoxicological problems. It includes basic ecotoxicological concepts, as well as information about chemicals and toxic substances that may cause harmful effects on the ecosystem and its living components. The book, with a total of 48 chapters, is divided into three parts. The first part includes the basic concepts of ecotoxicology, starting with an introductory chapter on ecotoxicology as a subdiscipline of ecology; assessment on ecotoxicological effects and risk; and properties and effects of toxic chemicals. These topics are further discussed throughout the book, along with nomenclature, focal topics, and the history of ecotoxicology. The two remaining parts tackle harmful properties and harmful chemicals. The second part also covers bioaccumulation, bioavailability, biodegradability, biodegradation, and biomagnification. It also provides models for ecotoxicological populations, ecosystems and landscapes, and on food-web bioaccumulation. Chemicals including benzene, copper, lead, nitrogen, phenols, pheromones, phthalates, plutonium, and uranium are covered in separate chapters in the final part. This book will be of great value to ecologists, ecotoxicologists, and environmental managers. - Provides an overview of the theory and application of global ecology - International focus and range of ecosystems makes Ecotoxicology an indispensable resource to scientists - Based on the bestselling Encyclopedia of Ecology - Full-color figures and tables support the text and aid in understanding

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 Power System Loads and Power System Stability written by Yue Zhu and published by Springer Nature. This book was released on 2020-01-16 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis develops a pioneering methodology and a concept for identifying critical loads and load model parameters in large power networks based on their influence on power system stability. The research described in the thesis first develops an automatic load modelling tool (ALMT) that can be used to automatically build load model from actual measured power system data without human intervention and the benefits of the ALMY are explored. Secondly, it develops a pioneering framework based on Morris screening method for ranking power system load model parameters based on their influence on overall power system stability (voltage, frequency, transient and small disturbance stability) considering different load models and loading conditions. Thirdly, a novel probabilistic methodology for determining the accuracy levels of critical load model parameters has been developed. This book will be of interest to students and researchers within the field of electrical engineering, as well as industry professionals.
Download or read book Atmospheric Ammonia written by Mark Sutton and published by Springer Science & Business Media. This book was released on 2008-12-30 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic emissions of ammonia cause a host of environmental impacts, including loss of biodiversity, soil acidification and formation of particulate matter in the atmosphere. Under the auspices of the UNECE Convention on Long Range Transboundary Air Pollution, around 80 international experts met to review the state of scientific knowledge. This book reports their analysis. It concludes that threshold levels for ammonia effects have been underestimated and sets new values, it assesses the independent evidence to verify reported reductions in regional ammonia emissions, and it reviews the uncertainties in modelling ammonia, both in "hot spots" and at the regional scale.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, eigenvalue algorithms used in the commercial software packages (AESOPS and PEALS) to analyze low frequency oscillations in large scale power systems have been explained in terms of commonly understood iterative schemes. These algorithms have been extended to include the calculation of any desired system mode. Next, the voltage instability problem has been addressed from a dynamic viewpoint in the context of critical modes of the linearized system matrix. The eigenvalue algorithms have been used to establish a correspondence between the critical modes and certain system states. Two case studies have been performed to analyze the dynamic nature of the voltage problem. Finally, Hopf bifurcation theory has been used to analyze the nonlinear power system at critical load levels.
