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.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Air Quality in the National Parks: A Summary of Findings From the National Park Service Air Quality Research and Monitoring Program The purpose of this report is to summarize findings from the nps air quality research and monitoring program based on data collected through 1987. This information helps the National Park Service to remedy and prevent resource degradation so that future generations can enjoy the parks in as natural a condition as possible. Visibility monitoring has shown that. In addition to natural sources of visibility impairment. There are varying degrees of visibility impairment from manmade pollution in virtually all monitored parks. Nps research findings suggest that fine sulfate particles are the single most important contributor to visibility impairment in most nps units. Fine sulfate particles, which can be transported long distances in the atmosphere. Are primarily the result of sulfur oxide emissions from energy and industrial sources. In the Colorado Plateau area. Where Grand Canyon National Park and several other nps units are located, fine sulfate particles are responsible for 40 to 60 percent of the visibility impairment. In eastern areas of the country. Fine sulfates play an even larger role in visibility impairment. In the Pacific Northwest. Sulfates are not the primary cause of visibility impairment; instead. Fine carbon from controlled burning of timber and agricultural land and natural forest fires plays a prominent role. Research on effects of visibility on the visitor experience in five nps units indicates that clean. Clear air is one of the most important features of these parks. It appears that visitors value an environment undisturbed by man above all other features of the parks. Research findings on the effects of changes in visual air quality suggest that a small increase in air pollution is more easily noticed and more disturbing to the human observer when the atmosphere is initially relatively clean.

Book excerpt: Great Basin Nat, Park encompasses over 77,000 acres of White Pine County in east-central Nevada. The National Park Service mgmt. plan identifies threats to air quality and visibility -- incl. air pollution from the possible development of coal-fired power plants in the region. In 2004 and 2006, two companies each initiated the process to build new coal-fired power plants about 55 miles northwest of Great Basin National Park. These new power plants could adversely affect air quality and visibility in and around the park. This report describes: (1) current air quality and visibility in and around Great Basin National Park; and (2) stakeholders' views about the potential impacts of the proposed coal-fired power plants on air quality and visibility in and around the park.
