Download or read book Ultraviolet Absorption Cross Sections of HO2NO2 Vapor written by Luisa T. Molina and published by . This book was released on 1980 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultraviolet absorption cross sections for gas phase HO2NO2 have been measured between 190 and 330 nm, at 298K and 1 atm total pressure. The HO2NO2 vapor was prepared in a flowing N2 stream in the presence of H2O, H2O2, HNO3, and NO2. The composition of the mixture was established by visible and infrared absorption spectroscopy and by chemical titration after absorption in aqueous solutions. The experimental uncertainty (one standard deviation) ranges from 5% at 200 nm to 30% at 330 nm, and mainly falls in the 10% range. The solar photodissociation rate in the troposphere and lower stratosphere is estimated to be about ten to the -5th power/sec for 0 deg solar zenith angle.

Download or read book Non Thermal Plasma Techniques for Pollution Control written by Bernie M. Penetrante and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid rain, global warming, ozone depletion, and smog are preeminent environmental problems facing the world today. Non-thermal plasma techniques offer an innovative approach to the solution of some of these problems. There are many types of non-thermal plasma devices that have been developed for environmental applications. The potential of these devices for the destruction of pollutants or toxic molecules has already been demonstrated in many contexts, such as nitrogen oxides (NOX) and sulfur dioxide (SO2) in flue gases, heavy metals and volatile organic compounds (VOCs) in industrial effluents, and chemical agents such as nerve gases. This book contains a comprehensive account of the latest developments in non-thermal plasma devices and their applications to the disposal of a wide variety of gaseous pollutants.
Download or read book Stratospheric Reactions of Peroxynitric Acid written by John Roger Barker and published by . This book was released on 1981 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both HO2 and NO2 play crucial roles in the chemistry of the upper atmosphere. For several years, these two species were thought to react via a radical disproportionation reaction, although it was suggested that a longer-lived complex could be formed according to reaction (1): HO2 + NO2 + M reversible reaction HOONO2 + M. The importance of reaction (1) has recently been verified by direct observation of HO2NO2 by Fourier transform infrared spectroscopy. Moreover, the rate of reaction (1) has been measured, and its reverse reaction ( -1) has been studied. Also, RRKM theory has been applied to these data for reaction ( -1) so that its rate can be reliably estimated as a function of both temperature and pressure. In another publication, the effect of HO2NO2 on tropospheric photochemical smog chemistry was discussed.

Download or read book Mechanisms of Atmospheric Oxidation of the Oxygenates written by Jack Calvert and published by OUP USA. This book was released on 2011-09-29 with total page 1634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by an international team of eminent atmospheric scientists, Mechanisms of Atmospheric Oxidation of the Oxygenates is an authoritative source of information on the role of oxygenates in the chemistry of the atmosphere. The oxygenates, including the many different alcohols, ethers, aldehydes, ketones, acids, esters, and nitrogen-atom containing oxygenates, are of special interest today due to their increased use as alternative fuels and fuel additives. This book describes the physical properties of oxygenates, as well as the chemical and photochemical parameters that determine their reaction pathways in the atmosphere. Quantitative descriptions of the pathways of the oxygenates from release or formation in the atmosphere to final products are provided, as is a comprehensive review and evaluation of the extensive kinetic literature on the atmospheric chemistry of the different oxygenates and their many halogen-atom substituted analogues. This book will be of interest to modelers of atmospheric chemistry, environmental scientists and engineers, and air quality planning agencies as a useful input for development of realistic modules designed to simulate the atmospheric chemistry of the oxygenates, their major oxidation products, and their influence on ozone and other trace gases within the troposhere.

This book was released on 2012-12-06 with total page 748 pages. Available in PDF, EPUB and Kindle. Book excerpt: In October 1979 the First European Symposium on Physico-Chemical Behaviour of Atmospheric Pollutants was held In Ispra (Italy); 83 scientists attended the conference contributing 44 papers. Ten years later, the Fifth European Symposium on Physico-Chemical Behaviour of Atmospheric Pollutants, organized as for the previous Symposia In the framework of the Concerted Action *COST 611, was held in Varese (Italy) from 25 to 28 September 1989. This Volume contains the oral papers and the posters presented at this Symposium. Participation at this Conference Is more than doubled of that In 1979 In terms of scientists (185) and contributed papers (110). This simple comparison demonstrates once more the growing attention of the scientific community to the problems related to the pollution of the atmosphere. During these years, Important new Issues have arisen (global pol lutlon/cl Imatlc changes) whl Ie old ones have been reviewed due to new experimental evidence (depletion of stratospheric ozone). The Symposium offered the best opportunity for a review of the current studies and technical progress achieved In the various sectors of the Concerted Action since the Fourth Symposium held In Stresa (Italy) In September 1986. In 1987 the scientific programme and the operational structures of the COST 611 Project were revised. The Project Is now structured into three Working Parties: 1. Development of Analytical Methods to measure Trace Components of the Atmosphere. 2. Atmospheric Chemical and Photochemical Processes. 3. Field measurements and their Interpretation.
Download or read book Protecting the Ozone Layer written by Edward A. Parson and published by Oxford University Press. This book was released on 2003-03-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive history of international efforts to protect the ozone layer, the greatest success yet achieved in managing human impacts on the global environment. Its arguments about how this success was achieved are both theoretically novel and of great significance for the management of other global problems, particularly global climate change. The book provides an account of the ozone-depletion issues from the first attempts to develop international action in the 1970s to the mature functioning of the present international regime. It examines the parallel developments of politics and negotiations, scientific understanding and controversy, technological progress, and industry strategy that shaped the issue's development and its effective management. In addition, the book offers important new insights into how the interactions among these domains influenced the formation and adaptation of the ozone regime. Addressing the initial formation of the regime, the book argues that authoritative scientific assessments were crucial in constraining policy debates and shaping negotiated agreements. Assessments gave scientific claims an ability to change policy actors' behavior that the claims themselves, however well known and verified, lacked. Concerning subsequent adaptation of the regime, the book identifies a series of feedbacks between the periodic revision of chemical controls and the strategic responses of affected industries, which drove rapid application of new approaches to reduce ozone-depleting chemicals. These feedbacks, promoted by the regime's novel technology assessment process, allowed worldwide use of the chemicals to decline further and faster than even the boldest predictions, by nearly 95 percent within ten years.
