Available in PDF, EPUB and Kindle. Book excerpt: Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. The formation of gaseous and particulate secondary products caused by oxidation of VOCs is one of the largest unknowns in the quantitative prediction of the earth’s climate on a regional and global scale, and on the understanding of local air quality. To be able to model and control their impact, it is essential to understand the sources of VOCs, their distribution in the atmosphere and the chemical transformations which remove these compounds from the atmosphere. In recent years techniques for the analysis of organic compounds in the atmosphere have been developed to increase the spectrum of detectable compounds and their detection limits. New methods have been introduced to increase the time resolution of those measurements and to resolve more complex mixtures of organic compounds. Volatile Organic Compounds in the Atmosphere describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyse gaseous and particulate organic compounds in the atmosphere. The aim is to provide an authoritative review to address the needs of both graduate students and active researchers in the field of atmospheric chemistry research.

Download or read book Airborne and Ground Based Measurements of Volatile Organic Compounds Using Proton Transfer Reaction Mass Spectrometry in Texas and Mexico City written by Edward Charles Fortner and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of ambient volatile organic compounds (VOCs) by proton transfer reaction mass spectrometry (PTR-MS) are reported from recent airborne and surface based field campaigns. The Southeast Texas Tetroon Study (SETTS) was a project within the TEXAQS 2005 field campaign, conducting airborne measurements that investigated the nocturnal Lagrangian transport of industrial plumes downwind of the Houston, Texas metropolitan area. On the evening of July 26-27, a polluted air mass with elevated mass 43, mass 45 and mass 57 VOCs along with elevated O3, CO, and NOx was tracked from the Houston metropolitan area to an area northwest of Shreveport, LA, a distance of over 200 miles. This campaign demonstrated that the PTRMS is capable of tracking a VOC plume over large distances and these measurements indicate that transport of VOCs, particularly light alkenes and their oxidation products, out of the Houston metropolitan area may need to be considered by areas downwind of the Houston area when they are determining how to attain their air quality goals. During the MILAGRO field campaign in March 2006 VOCs were measured by PTR-MS instrumentation on a rooftop in the urban mixed residential and industrial area north northeast of downtown Mexico City. Diurnal profiles of weekday and weekend/holiday aromatic VOC concentrations clearly show the influence of vehicular traffic during the morning rush hour time period and during the afternoon hours although a separate late afternoon peak is not seen. Plumes of toluene elevated as much as 216 parts per billion by volume (ppbv) and ethyl acetate elevated as much as 183 ppbv above background levels were observed during the late night and early morning hours. These plumes indicate the probability of significant industrial sources of these two compounds in the region. The high levels of toluene measured by our PTR-MS exceed levels that would be predicted by examination of the Mexico City Metropolitan Area (MCMA) emission inventory and when these VOC measurements are integrated with measurements conducted throughout the MCMA a better understanding of both the overall spatial pattern of VOCs in the MCMA as well as its variability will be attained.

Download or read book Rethinking the Ozone Problem in Urban and Regional Air Pollution written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution in the lower atmosphere, or troposphere, threatens the health of humans, animals, and vegetation. This book discusses how scientific information can be used to develop more effective regulations to control ozone. Rethinking the Ozone Problem in Urban and Regional Air Pollution discusses: The latest data and analysis on how tropospheric ozone is formed. How well our measurement techniques are functioning. Deficiencies in efforts to date to control the problem. Approaches to reducing ozone precursor emissions that hold the most promise. What additional research is needed. With a wealth of technical information, the book discusses atmospheric chemistry, the role of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in ozone formation, monitoring and modeling the formation and transport processes, and the potential contribution of alternative fuels to solving the tropospheric ozone problem. The committee discusses criteria for designing more effective ozone control efforts. Because of its direct bearing on decisions to be made under the Clean Air Act, this book should be of great interest to environmental advocates, industry, and the regulatory community as well as scientists, faculty, and students.

Available in PDF, EPUB and Kindle. Book excerpt: Interest in volatile organic compounds (VOCs) as air pollutants has increased dramatically in recent years. This book covers a number of very topical issues concerning VOCs, including stratospheric ozone depletion due to CFCs, and the properties of alternative substances; the role of VOCs in the photochemical formation of lower atmosphere (tropospheric) ozone; and the problem of the direct toxicity of VOCs such as benzene and formaldehyde. This Issue reviews our current knowledge of VOCs, drawing upon the expertise of renowned experts and major national and international research programmes. It examines man-made and natural sources, as well as pathways and chemical reactions in the atmosphere. It also looks closely at the sources and concentrations of VOCs indoors, where humans are most likely to be exposed to them. Volatile Organic Compounds in the Atmosphere describes techniques used for the calculation of emissions inventories and strategies for control, and explores the many Government policy matters relating to VOCs. It provides readers with in-depth, clearly explained coverage of the many complex scientific and policy issues surrounding VOCs in the atmosphere.
