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 excerpt: Volatile Organic Compounds (VOCs) have anthropogenic and biogenic origins. At the Earth's scale, the natural sources represent a great part of the total VOCs present in the atmosphere but in industrialized regions, anthropogenic ones become the majority due to the various human activities related mainly to chemical industries (liquid fuels, solvents, thinners, detergents, degreasers, cleaners and lubricants). Almost all VOCs have effects on human health and many of them are even carcinogenic. It is also known that the VOCs can affect the central nervous system and may have mutagenic effects. Apart from human health, they also play an important role towards the environment, especially in the atmospheric pollution processes. Indeed, VOCs emissions lead to the promotion of photochemical reactions in the atmosphere (ozone formation, depletion of the stratospheric ozone layer and formation of photochemical smog). The present book gathers and presents some current research from across the world conducted by scientific experts in their fields. In seven valuable contributions, it deals with the emission and the environmental impact as well as the control of the Volatile Organic Compounds.

This book was released on 2013-11-19 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogenic volatile organic compounds (BVOC) play a critical role in biosphere–atmosphere interactions and are key constraints of the physical and chemical properties of the atmosphere, potentially influencing the climate and the quality of air, especially in the areas exposed to in situ release or long-range transport of anthropogenically polluted air masses. Under these conditions, reactive BVOC may contribute to ozone and particle production. The very large amount of BVOC emitted by vegetation, estimated today to more than 1000Tg C annually, is dominated by methanol and isoprenoids, released predominantly by forest species. Such a high rate of emission implies a large metabolic cost and hence likely indicates very important plant functional roles for these compounds. BVOC can be emitted by plants constitutively, or the emission may be induced in response to biotic and abiotic factors. Both constitutive and induced isoprenoids often act as defensive compounds and are crucial for plant protection in stressful environments. The importance of volatile isoprenoids as protecting molecules has been widely discussed. However, based on the use of genetically modified plants and novel technologies that allow detection of BVOC oxidation products, the idea is emerging that especially volatile isoprenoids act as antioxidants in planta, whereas they contribute to the oxidation potential of the atmosphere.

This book was released on 2013-07-08 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-driven volatile organic compound (BVOC) emissions play a major role in atmospheric chemistry, including ozone and photochemical smog formation in the troposphere, and they extend the atmospheric lifetime of the key greenhouse gas, methane. Furthermore, condensation of photo-oxidation products of BVOCs leads to formation of secondary organic aerosols with profound implications for the earth's solar radiation budget and climate. Trees represent the plant life form that most contributes to BVOC emissions, which gives global forests a unique role in regulating atmospheric chemistry. Written by leading experts in the field, the focus is on recent advancements in understanding the controls on plant-driven BVOC emissions, including efforts to quantitatively predict emissions using computer models, particularly on elicitation of emissions under biotic and abiotic stresses, molecular mechanisms of volatile synthesis and emission and the role of emissions in plant stress tolerance.

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.

Abstract: Abstract of thesis entitled BIOGENIC VOLATILE ORGANIC COMPOUND EMISSIONS IN HONG KONG Submitted by Jeanie Kin-Yin Tsui For the degree of Master of Philosophy at The University of Hong Kong in November 2006 Plants emit diverse non-methane hydrocarbons which are collectively known as biogenic volatile organic compounds (BVOCs). It has been proposed that BVOCs may help plants to defend against high temperature and ozone stresses. BVOCs, however, are also found to be important contributors to the formation of tropospheric ozone and other secondary pollutants. Hong Kong is located at the southeastern coast of China. In spite of its small area (1100 km ), Hong Kong has highly diverse flora (3164 species) most of which are tropical. Although urban greening programs have been promoted as an approach to improve air quality and living environment in Hong Kong, it is still not well understood the possible role of pollutants including volatile organic compounds from biogenic sources in the deterioration of air quality. The cultivation of some tree species may in fact exacerbate air pollution due to their high BVOC emissions. The present project was set out as a first step to investigate BVOC emissions in Hong Kong, in the hope of providing a primary understanding of the topic in a local context. The emission rates of isoprene and monoterpene of thirteen local tree species were determined by enclosure measurement. Among them, six species were identified as isoprene emitters, and two species were identified as monoterpene emitters. Bauhinia variegata var. candida and Eucalyptus robusta were found to be the highest isoprene and monoterpene emitters, respectively. Light and temperature dependencies of BVOC emissions were also investigated with two tree species: Bauhinia variegata var. candida and Eucalyptus torelliana. Both light intensity and temperature were found to be critical factors that determine the rates of isoprene and monoterpene emissions from plants; high BVOC emissions were triggered by high temperature and high light intensity. 2 A BVOC emission model of a spatial resolution of 0.1 0.1 km and a time resolution of 1 hour was established based on detailed land use, tree distribution and hourly meteorological data. The total annual BVOC emissions from 1 August 2004 to 9 31 July 2005 were estimated to be 11326 metric tons [9.2 x 10 g C (BVOC carbon)]. Isoprene, total monoterpene (TMT) and other VOCs (OVOCs) emissions account for 25.9%, 34.1 %, and 40% of the total emissions. Prominent diurnal and seasonal variations in BVOC emissions were also predicted by the model. The present study offered a primary evaluation of BVOC emissions in Hong Kong, and laid a solid foundation for further investigation on the topic.
