VAN VELZEN Commission of the European Communities, Joint Research Centre Ispra, Environment Institute, 1-21020 Ispra (Varese) ITAL Y 1. Introduction Worldwide, there is an ever increasing interest and concern about the destructive effects of air pollution on man's ecosystem. The growing awareness of these effects has revealed the need to take adequate measures to minimize the emission of air polluting products. The two most important contaminants, occurring in the largest concentrations and quantities, are sulphur dioxide and nitrogen oxides. Both pollutants are formed mainly during the combustion of fossil fuels, particularly by power stations and traffic. The effects of air pollution caused by these two contaminants have already been studied for several decades and measures to protect the environment against their adverse effects are now operative in many countries. The present volume contains the proceedings of a Eurocourse held in Ispra in September 1990. The course was meant to give an overview of present knowledge concerning the emission sources and quantities, to cover features of present legislation and to give a survey of the most important modern abatement techniques for S02 and NOx. It was mainly addressed to higher and medium management in the power, chemical and similar industries, particularly from those countries where the fight against air pollution is still in its infancy. Obviously, it was not possible to cover completely the whole range of subjects during the limited duration of a Eurocourse.

Download or read book The Mechanisms of Reactions Influencing Atmospheric Ozone written by Jack G. Calvert and published by Oxford University Press. This book was released on 2015-05-13 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ozone, an important trace component, is critical to life on Earth and to atmospheric chemistry. The presence of ozone profoundly impacts the physical structure of the atmosphere and meteorology. Ozone is also an important photolytic source for HO radicals, the driving force for most of the chemistry that occurs in the lower atmosphere, is essential to shielding biota, and is the only molecule in the atmosphere that provides protection from UV radiation in the 250-300 nm region. However, recent concerns regarding environmental issues have inspired a need for a greater understanding of ozone, and the effects that it has on the Earth's atmosphere. The Mechanisms of Reactions Influencing Atmospheric Ozone provides an overview of the chemical processes associated with the formation and loss of ozone in the atmosphere, meeting the need for a greater body of knowledge regarding atmospheric chemistry. Renowned atmospheric researcher Jack Calvert and his coauthors discuss the various chemical and physical properties of the earth's atmosphere, the ways in which ozone is formed and destroyed, and the mechanisms of various ozone chemical reactions in the different spheres of the atmosphere. The volume is rich with valuable knowledge and useful descriptions, and will appeal to environmental scientists and engineers alike. A thorough analysis of the processes related to tropospheric ozone, The Mechanisms of Reactions Influencing Atmospheric Ozone is an essential resource for those hoping to combat the continuing and future environmental problems, particularly issues that require a deeper understanding of atmospheric chemistry.

This book was released on 2012-12-06 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is no shortage of general books on the subject of acid rain, or of symposium proceedings reviewing work ranging from atmospheric chemistry and deposition processes to freshwater acidification and effects on vegetation. In contrast, the collection of papers from this Workshop is focussed on a much smaller subject, the processes of acid deposition at high altitude sites. Interest in deposition at high elevation sites comes largely from observed vertical gradients in the degree of forest damage at sites in the Federal Republic of Germany and the eastern United States. These gradients show that damage to Norway spruce and fir increases with altitude at sites in Bavaria and the Black Forest, and that Red spruce are declining at high elevation sites in the Appalachian Mountains. With the large scale of scientific interest in forest decline, cany research groups, during the last five years, have been examining atmospheric chemistry, deposition processes, and effects on vegetation and soils at upland sites. In particular there have been many recent studies of cloud and precipitation chemistry, which show much larger concentrations of all ions in cloud water than in rain or snow. These studies have also shown that processes of wet and dry deposition and also the chemistry of the air at hill tops are modified strongly by orographic effects.

This book was released on 2013-06-29 with total page 773 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapidly increasing interest in the problems of air pollution and source-receptor relationships has led to a significant expansion of knowledge in the field of atmospheric chemistry. In general the chemistry of atmospheric trace constituents is governed by the oxygen content of the atmosphere. Upon entering the atmosphere in a more or less reduced state, trace substances are oxidized via various pathways and the generated products are often precursors of acidic compounds. Beside oxidation processes occurring in the gas phase, gaseous compounds are often converted into solid aerosol particles. The various steps within gas-to-particle conversion are constantly interacting with condensation processes, which are caused by the tropospheric water content. Thus in addition to the gaseous state, a liquid and solid state exists within the troposphere. The solid phase consists of atmospheric conversion products or fly ash and mineral dust. The liquid phase consists of water, conversion products and soluble compounds. The chemistry occurring within this system is often referred to as hydrogeneous chemistry. The chemist interprets this term, however, more strictly as reactions which occur only at an interphase between phases. This, however, is not always what happens in the atmosphere. There are indeed heterogeneous processes such as reactions occurring on the surface of dry aerosol particles. But apart from these, we must focus as well on reactions in the homogeneous phase, which are single steps of consecutive reactions running through various phases.

This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1988 the "'Third Oberursel Symposium" devoted to the problems of input of pollutions into forest-ecosystems and their effects on plants or soil convened. After several years of intensive research on the effects of pollutions on forest ecosystems it is obvious that not a single specific pollutant can be made responsible but a mixture of several components act together or interact with each other. The contributions of the workshop _ reflect to a large extend the results of research projects which were started at the beginning of the eighties. They review our improved knowledge on the patterns of concentration, of the mechanism of wet and dry deposition and fog interception, modelling studies and the effect of the processes on plant receptors and surfaces. Since the 1985 symposium the pathways of pollutants leading to biological damage have been examined and are more clearly recognised. The book reflects the common interest and the continuous effort of scientists from many different disciplines to better understand the physical and chemical processes which finally lead to the observed damage of forest-trees. Comparing the conclusions of the contributions of this book _ with the results of the first Oberursel symposium in 1981, our knowledge on the relevance of the different mechanisms leading to forest-decay has been considerably improved. The book indicates also in which directions future work should be concentrated. Again, I have to thank the authors for their cooperation by submitting their recent research-results.

Available in PDF, EPUB and Kindle. Book excerpt: The alarming consequences of global climate change have highlighted the need to take urgent steps to combat the causes of air pollution. Hence, understanding the Earth's atmosphere is a vital component in Man's emerging quest for developing sustainable modes of behaviour in the 21st century. Written by a team of expert scientists, the Handbook of Atmospheric Science provides a broad and up-to-date account of our understanding of the natural processes that occur within the atmosphere. It examines how Man’s activities have had a detrimental effect on the climate, and how measures may be implemented in order to modify these activities. The book progresses through chapters covering the principles of atmospheric science and the current problems of air pollution at the urban, regional and global scales, to the tools and applications used to understand air pollution. The Handbook of Atmospheric Science offers an excellent overview of this multi-disciplinary subject and will prove invaluable to both students and researchers of atmospheric science, air pollution and global change.

Download or read book Atmospheric Chemistry written by Detlev Möller and published by Walter de Gruyter GmbH & Co KG. This book was released on 2022-05-09 with total page 936 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work in your hand contains three main chapters, covering the chemistry of the condensed phase in the atmosphere, first, the different forms of atmospheric waters (precipitation, fog and clouds, dew), and secondly dust, now mostly termed particulate matter and, more scientifically, atmospheric aerosol. A third section treats the gases in the atmosphere. An introductory chapter covers the roots of the term atmospheric chemistry in its relations to chemistry in general and biogeochemistry as the chemistry of the climate system. Furthermore, a brief overview of understanding chemical reactions in aqueous and gaseous phase is given. It is my aim to pay respect to all persons who studied the substances in the air, to those who made small, and to them who made giant contributions for the progress in atmospheric science. I’m not a historian who is able to present the past from a true perspective of their time – this also would not be my aim. If possible, however, I try to interpret the past – almost limited to experimental fi ndings in the nineteenth century – through current values, without dismissal of the problems and ideas of earlier scientists. In this way it is possible to draw some ideas on the historical chemical state of the air. Hence, I name this voyage critical. However, nowhere in this book it is my attention to express my criticism to colleagues and scientifi c ancestors. Great scientists too were subject to errors; doing science consists from the permanent loop observation, interpretation, conclusion, and again testing against new observation. If this volume can contribute more than to be “a nice story” on atmospheric chemistry, then hopefully it inspires the reader to more critical reading of scientifi c publications, and, not to forget the older one.
