Available in PDF, EPUB and Kindle. Book excerpt: A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

Download or read book Geography of Nitrate and Sulfate Atmospheric Wet Deposition in the Southern Rocky Mountains written by Ivan Guillermo Valles and published by . This book was released on 2018 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data from the National Atmospheric Deposition Program’s National Trends Network, the United States Geological Survey’s Rocky Mountain Regional Snowpack Chemistry Program and the United States Environmental Protection Agency’s Air Markets Program were analyzed to identify spatial relationships amongst atmospheric wet deposition concentrations of nitrate and sulfate. The analysis relates atmospheric wet deposition, commonly known as acid rain, to two distinct variables—as a function of elevation and also as a function of proximity to major regional electricity generating stations. This study focuses on the Southern Rocky Mountain region of the United States, and integrates depositional and emissions point-source data from Arizona, Colorado, New Mexico, Utah, and Wyoming. Previous studies have identified wide-ranging adverse effects upon terrestrial and aquatic ecosystems such as nitrogen saturation, changes in plant biodiversity, and soil nutrient cycling where atmospheric wet deposition is the suspected primary means of pollutant transport and delivery. Atmospheric wet deposition then possess the ability to, in a broad sense, impair the United States’ agricultural, economic, and public health sectors; as a result, the United States Congress, beginning in the 1970’s had legislated a number of acts and amendments funding research focused on studying and attenuating airborne pollution. However, the spatiotemporal geography of atmospheric wet deposition has been understudied and limited in scope, especially across the Western United States’ high elevation lifezones. As a result, it is currently difficult to assess how the depositions of nitrate and sulfate will respond spatially or temporally as a function of emissions outputs of nitrous and sulfurous oxides from major regional electricity generating facilities. This research builds upon the existing geographic knowledge of atmospheric wet deposition by combining precipitation, snowpack, and emission datasets to analyze specific spatial relationships. The study concludes that levels of atmospheric wet deposition concentrations do in fact show trend changes in relation to elevation; it also finds that atmospheric wet deposition concentrations show relationships that strengthen with increased proximity to regional electricity generating stations. The significance of this research is that the spatial distribution of atmospheric wet deposition is discernible, and with improved application and design, likely capable of forecasting the phenomenon.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Many changessome discouraging, others hopefulhave occurred in the Rocky Mountain region since the first edition of this widely acclaimed book was published. Wildlife habitat has become more fragmented, once-abundant sage grouse are now scarce, and forest fires occur more frequently. At the same time, wolves have been successfully reintroduced, and new approaches to conservation have been adopted. For this updated and expanded Second Edition, the authors provide a highly readable synthesis of research undertaken in the past two decades and address two important questions: How can ecosystems be used so that future generations benefit from them as we have? How can we anticipate and adapt to climate changes while conserving biological diversity?

Download or read book Rocky Mountain National Park Initiative Nitrogen Deposition Reduction Contingency Plan written by and published by . This book was released on 2010 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of atmospheric nitrogen (N) deposition relative to the natural processes and natural character of Rocky Mountain National Park (RMNP) has become better understood over time, as scientific research and monitoring that began in the early 1980's have documented various changes to ecosystems in the park. These changes include forest and soil biogeochemical changes, enhanced microbial activity in soils, increased N in lakes and streams, changes in surface water chemistry, altered tree chemistry, and shifts in species of aquatic plants. The park's unique resources will continue to be harmed if N deposition remains constant or increases. In 2004 a multi-agency meeting including the Colorado Department of Public Health and Environment (CDPHE), the National Park Service (NPS), and the U.S. Environmental Protection Agency (EPA) was held to address the effects and trends of N deposition in RMNP, and related air quality issues including elevated ozone concentrations and visibility impairment.

This book was released on 2021-03-11 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Systems Ecology Paradigm (SEP) incorporates humans as integral parts of ecosystems and emphasizes issues that have significant societal relevance such as grazing land, forestland, and agricultural ecosystem management, biodiversity and global change impacts. Accomplishing this societally relevant research requires cutting-edge basic and applied research. This book focuses on environmental and natural resource challenges confronting local to global societies for which the SEP methodology must be utilized for resolution. Key elements of SEP are a holistic perspective of ecological/social systems, systems thinking, and the ecosystem approach applied to real world, complex environmental and natural resource problems. The SEP and ecosystem approaches force scientific emphasis to be placed on collaborations with social scientists and behavioral, learning, and marketing professionals. The SEP has given environmental scientists, decision makers, citizen stakeholders, and land and water managers a powerful set of tools to analyse, integrate knowledge, and propose adoption of solutions to important local to global problems.

Available in PDF, EPUB and Kindle. Book excerpt: This volume ‘Agrochemicals in Soil and Environment: Impacts and Remediation’ is a comprehensive collection of important literature on agrochemical contamination. The main focus of this book is to point out undesirable changes in biological, physical and chemical characteristics of agricultural soils and its impacts on global agricultural crop productivity. Soil is one of the important resources of basic needs for our sustenance but due to various anthropogenic activities like urbanization and industrialization, the soil is losing its basic quality characteristics. Soil microorganisms, water holding capacity, minerals, salts and nutrients are under the direct threat due to agrochemicals therefore, agricultural sector is facing a serious challenge. Lack of proper knowledge and luxurious applications of agrochemicals resulting into degradation and deterioration of soil quality, loss of soil and crop productivity and threatening the food security. Therefore, it is imperative to develop indices, indicators and soil parameters for the monitoring and impact assessment of agricultural contaminants. Further, biotic and abiotic stresses and their tolerance mechanisms in plants in relation to the soil contaminants such as toxic pollutants, heavy metals, inorganic and organic matters, variety of pesticides, insecticides, herbicides, agricultural runoffs and solid wastes, and chemical fertilizers are also highlighted in this volume. This book also discusses causes of reduced agriculture productivity and suggests sustainable measures such as plant-based technologies, bioremediation and nanotechnology, that can be used to overcome the crop losses. The book is interest to research students, teachers, agricultural scientists, agronomists, environmentalists as well as policy makers.

Book excerpt: “An eclectic, enjoyable mix of literature reviews, personal experience and case studies, and practical advice from . . . leaders in their subdisciplines.” —Eleanor J. Sterling, Chief Conservation Scientist, Center for Biodiversity & Conservation, American Museum of Natural History With the US National Park Service over one hundred years old, parks and protected areas worldwide are under increasing threat from storms and fires of greater severity, plant and animal extinctions, the changing attitudes of a public that has become more urbanized, and the political pressures of narrow special interest groups. In the face of such rapid environmental and cultural changes, Science, Conservation, and National Parks gathers a group of renowned scholars—including Edward O. Wilson, Jane Lubchenco, Thomas Dietz, and Monica Turner—who address these problems and in the hope of securing a future for protected areas that will push forward the frontiers of biological, physical, and social science in and for parks. Contributors provide answers to a number of key conservation questions, such as: How should stewardship address climate change, urban encroachment and pollution, and invasive species? How can society, especially youth, become more engaged with nature and parks? What are appropriate conservation objectives for parks in the Anthropocene? Charting a course for the parks of the next century, Science, Conservation, and National Parks catalyzes the continued evolution of US park conservation policy, and serves as an inspiration for parks, conservation, and management worldwide. “Offers a refreshing holistic treatment of the linkages and mutual dependencies between parks and science. Compelling.” —William B. Monahan, USDA Forest Service and formerly of the US National Park Service “This is a testament to what can be achieved by determined conservationists.” —Biodiversity and Conservation journal
