This book was released on 2012-12-06 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The public's attitude toward air pollution in the United States evolved substantially during the 1960s. One of the results of the nation's emerging environmental ethic was the creation of the U. S. Environmental Protection Agency (EPA) in December of 1970. Prior to this time, research was focused on the impacts of air pollution on human health and welfare and was largely conducted by several federal research agencies, which included the Department of Health, Education, and Welfare; the National Oceanic and Atmospheric Administration; and the U. S. Department of Agricul ture. After the creation of the EPA, much of this work was consolidated in one regulatory agency, which resulted in periodic evaluations of the various effects of atmospheric pollution on human health, materials, agriculture, and forest ecosystems. At the same time that environmental interest was growing in the United States, concern increased in the European scientific community and public over the ecological impacts of acidic deposition. As the magnitude of the damage to European lakes and streams and the widespread decline in Norway spruce and silver fir was reported, concern that similar problems were occurring in the United States increased substantially. This concern was heightened by press reports of high elevation spruce-fir forest declines in the Adirondack and Appalachian Mountains and the decline and death of sugar maples in the northeastern United States and Canada.

Download or read book Air Pollutants and the Leaf Cuticle written by Kevin E. Percy and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant leaves are covered by a thin, lipoidal, non-living membrane called the cuticle. Forming the interface between plants and the atmospheric environment, it presents an effective barrier to pollutant entry. The book provides a comprehensive review of air pollutant effects on the cuticle and covers the following thematic areas: - Cuticular physicochemical characteristics, physiological, regulatory, and protective roles. - Effects, mechanisms, and consequences of air pollutant interaction with leaf cuticles. - Non-anthropogenic and environmental influences on the cuticle and potential of the cuticle for biomonitoring and critical levels mapping. - New developments in experimental methodology and analytical techniques.

This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of air pollution effects on vegetation has made rapid progress in the last five years. Growing concerns about effects of future increases in temperature and carbon dioxide (C0 ) levels on plant life have altered 2 the perspective of plant biologists in the field of pollutant-plant inter actions. In many cases, it is anticipated that crops and trees will increasingly experience multiple stresses in an altered environment: an environment in which physiological processes will no longer be matched to climate. Because of this problem, a major part of the focus of the air pollution effects research has shifted since 1987. Moreover, recent advances in our understanding of plant metabolic and molecular responses to stress have made it clear that many abiotic stresses elicit similar fundamental mechanisms. Adaptation responses to drought, extremes of temperature, xenobiotics and air pollutants are now known to involve the response of both specific and common resistance mechanisms, which often include altered gene expression. The field of air pollution effects on vegetation has benefitted greatly from this unification since results obtained and advances made in allied fields are now directly relevant. The advent of molecular genetics has made possible the production of transgenic plants containing altered amounts of resistance gene products which enables the posing of experimental questions which could not be addressed only five years ago. Hypotheses concerning the relevance of specific metabolites and processes to known responses to air pollution stress can now be tested.
Download or read book Ecology and Decline of Red Spruce in the Eastern United States written by Mary B. Adams and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s there were several published reports of recent, unexplained increases in mortality of red spruce in the Adirondack Mountains and the northern Appalachian Mountains of the eastern United States. These reports coincided with documentation of reductions in radial growth of several species of pine in the southeastern United States, and with the severe, rapid, and widespread decline of Norway spruce, silver fir, and some hardwoods in central Europe. In all of these instances, atmospheric deposition was hypothesized as the cause of the decline. (Throughout this volume, we use the term "decline" to refer to a loosely synchronized regional-scale deterioration of tree health which is brought about by a combination of stress factors. These may be biotic or abiotic in nature, and the combinations may differ from site to site. ) Heated public debate about the causes and possible cures for these forest declines ensued. Through the course of this debate, it became clear that information about forest health and air pollution effects on forests was inadequate to meet policymakers' needs. Ecology and Decline of Red Spruce in the Eastern United States addresses that gap for eastern spruce fir forests and represents the culmination of a great deal of research conducted in recent years. The focus is on red spruce because the decline of red spruce was both dramatic and inexplicable and because of the great amount of information gathered on red spruce.
