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.
Book Synopsis Volatile Organic Compounds in the Atmosphere by : Ralf Koppmann
Download or read book Volatile Organic Compounds in the Atmosphere written by Ralf Koppmann and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 512 pages. 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.

Book Synopsis Hybrid Targeted-nontargeted Analysis of Environmental Air Samples by : Brittany Marie Argento
Download or read book Hybrid Targeted-nontargeted Analysis of Environmental Air Samples written by Brittany Marie Argento and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air pollution is a global issue which has an impact on various aspects of life with a vast range of pollutants being monitored with different methods. One class of pollutants is the volatile organic compounds and their presence in the air requires improved methods to accurately report the contaminants present. Improved reporting is necessary as current methods are designed to report target compounds, but other volatile organic compounds present in the air can slip through the cracks using these target lists. Therefore, traditional methods have the risk of compounds being missed due to them not being on the target lists. These unknown compounds could also be important in monitoring air quality due to their impact on human health. New methods are needed to determine the presence of both target compounds and unknown compounds through nontargeted analysis. These methods are referred to as hybrid targeted-nontargeted methods and in this work, this is possible using comprehensive two-dimensional gas chromatography. This instrumentation coupled with thermal desorption enables a hybrid targeted-nontargeted method for the analysis of volatile organic compounds in air. Applying this instrumentation to environmental air monitoring can allow for complex samples to be analyzed with more compounds being detected over traditional methods. Method development has taken place to create a hybrid targeted-nontargeted method for volatile organic compounds in the atmosphere using thermal desorption. Coupling the hybrid method to thermal desorption allows for increased detection of analytes while also simplifying the sample preparation process. Here the separation parameters were optimized as well as conditions for both stages of the thermal desorption process. Furthermore, the sensitivity of the method was examined through limits of detection and limits of quantification. Various applications of the hybrid method have been explored both in outdoor applications and indoor locations to see the variety of volatile compounds which can be present. Overall, a novel hybrid targeted-nontargeted method has been developed for the purpose of air monitoring with the eventuality of being used in an environmental monitoring laboratory. Field applications have shown that there are many compounds which can be present in the air are not on the target list. The work seen in this MSc. thesis has provided a groundwork for a hybrid method for the detection of volatile organic compounds in the air which can be employed for better monitoring of air quality.
