This book was released on 2013-06-29 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic troposphere (0 to ca. 8 km) plays an important role in environmental concerns for global change. It is a unique chemical reactor influenced by human activity and the Arctic ocean. It is surrounded by industrialized continents that in winter contribute gaseous and particulate pollution (Arctic haze). It is underlain by the flat Arctic ocean from which it is separated by a crack-ridden ice membrane 3 to 4 m thick. Ocean to atmosphere exchange of heat, water vapor and marine biogenic gases influence the composition of the reactor. From September 21 to December 21 to March 21, the region north of the Arctic circle goes from a completely sunlit situation to a completely dark one and then back to light. At the same time the lower troposphere is stably stratified. This hinders vertical mixing. During this light period, surface temperature reaches as low as -40°C. In this environment, chemical reactions involving sunlight are generally much slower than further south. Thus, the abundance of photochemically reactive compounds in the atmosphere can be high prior to polar sunrise. Between complete dark in February and complete light in April, a number of chemical changes in the lower troposphere take place.
Download or read book Air Pollution and Community Health written by Frederick W. Lipfert and published by John Wiley & Sons. This book was released on 1994-05-17 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Pollution and Community Health A Critical Review and Data Sourcebook Frederick W. Lipfert Air pollution has affected community health since the advent of the industrial age and arguably since the discovery of fire. While organized societies have taken important steps to reduce and control emissions, the quality of the air we breathe today remains a critical concern. Air Pollution and Community Health transforms the major epidemiological works of the past 40 years into a coherent picture of the effects of air pollution on respiration, hospitalization, and mortality. The book re-evaluates these studies to clarify their findings within a consistent analytical framework and to define statistical relationships between various measures of community health and air quality. Lipfert emphasizes observational studies and the quality of the data used. The book is organized by health endpoint rather than by pollutant, beginning with the major air pollution disasters that helped galvanize the environmental revolution. His analysis shows that community air pollution acts primarily to exacerbate existing conditions in susceptible individuals, rather than to create new cases of respiratory disease. He concludes that "the alarms that sounded over 40 years ago are still ringing"--substantial health risks are still presented by the current urban mixtures of air pollution. Many of the studies reviewed suggest that the current ambient air quality standards required by the Clean Air Act fail to protect the health of the most susceptible individuals. Further, because of the role of natural sources of air pollution, questions are raised as to whether complete protection can ever be achieved. The book presents data from many of the epidemiological studies reviewed, including those of the major disasters of 1930-1960. Graphical presentations are featured for easy reference; many new analyses are presented here for the first time. The book also includes introductory chapters on air pollution, statistical analysis, and respiratory physiology, for the convenience of readers who may not be well versed in all of these topics. The major technical chapters on mortality and hospitalization include reviews of the effects of air pollution episodes, time-series analyses, cross-sectional studies, and long-term studies of pollution abatement. The chapters on respiratory function include both the effects of air pollution on function and the role of lung function as an independent predictor of longevity. Air Pollution and Community Health presents one of the first comprehensive analyses of the subject. It should be used to re-examine the effectiveness of air pollution research and control policies in the United States and is essential reading for all professionals involved in air pollution control or public health.

Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric chemistry is central to understanding global changes ? ozone depletion, appearance of the polar ozone holes, and compositional changes which worsen the greenhouse effect. Because of its importance, work is progressing on many fronts.This volume emphasizes the troposhere and stratosphere and has chapters on gas phase, condensed phase, and heterogeneous chemistry. Present progress is emphasized, and important future directions are also described.This book fills a need not satisfied by any others and will be popular for some years to come. It informs students and newcomers to the field of the many facets of atmospheric chemistry and can be used as a text for advanced students. It is also a valuable desk reference summarizing activities by quite a number of the most active research groups.Chapter 18 by Kolb et al. on heterogeneous chemistry is especially noteworthy because it represents a unique joint effort by several groups working on a very timely subject; they describe a conceptual framework and establish conventions which will be standard in future papers on this subject.
Download or read book Air Pollution by Photochemical Oxidants written by Robert Guderian and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochemical oxidants are secondary air pollutants formed under the influence of sunlight by complex photochemical reactions in air which contains nitrogen oxides and reactive hydrocarbons as precursors. The most adverse components formed by photochemical reactions in polluted air are ozone (0 ) 3 and peroxyacetyl nitrate (PAN), among many other products such as aldehydes, ketones, organic and inorganic acids, nitrates, sulfates etc. An analysis and evaluation of the available knowledge has been used to characterize the relationships among emissions, ambient air concentrations, and effects, and to identify the important controlling influences on the formation and effects of photochemical oxidants. The biological activity of photochemical oxidants was first clearly manifested during the early 1940's, when vegetation injury was observed in the Los Angeles Basin in the United States. Since that time, as a consequence of the increasing emissions of photochemical oxidant precursors, the photochemical oxidants have become the most important air pollutants in North America. In other parts of the world, for example South and Central America, Asia, and Australia, photo chemical oxidants threaten vegetation, particularly the economic and ecological performance of plant life. According to my knowledge, the first observations of ozone and PAN injury to vegetation in Europe were made by Dr. Ellis F. Darley (Statewide Air Pollution Research Center, University of California, Riverside, California) during a study visit (1963/64) to the Federal Republic of Germany.

Download or read book Transport and Chemical Transformation of Pollutants in the Troposphere written by Peter Borrell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major environmental concern is the increasing burden on all scales of photo-oxidants, acidifying substances and potential nutrients in the troposphere. These lead to episodes of summer smog, and appreciable damage to eco-systems both on land and at sea. Underlying the environmental effects is the complex scientific problem of linking the man-made and biological emissions to the myriad chemical reactions that transform the pollutants as they are transported to and deposited in the surroundings and also pristine areas remote from the sources. The project, the scientific results of which are described in this book, was set up to study the problem in an inter-disciplinary way by co-ordinating the work of more than 150 research groups in some 20 countries.
