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: This book discusses the water and carbon cycle system in the permafrost region of eastern Siberia, Providing vitalin sights into how climate change has affected the permafrost environment in recent decades. It analyzes the relationships between precipitation and evapotranspiration, gross primary production and runoff in the permafrost regions, which differ from those intropical and temperate forests. Eastern Siberia is located in the easternmost part of the Eurasian continent, and the land surface with underlying permafrost has developed over a period of seventy thousand years. The permafrost ecosystem has specific hydrological and meteorological characteristics in terms of the water and carbon dynamics, and the current global warming and resulting changes in the permafrost environment are serious issues in the high-latitude regions. The book is a valuable resource for students, researchers and professionals interested in forest meteorology and hydrology, forest ecology, and boreal vegetation, as well as the impact of climate change and water-carbon cycles in permafrost and non-permafrost regions.

Available in PDF, EPUB and Kindle. Book excerpt: Proton Transfer Reaction Mass Spectrometry (PTR-MS) is a rapidly growing analytical technique for detecting and identifying very small quantities of chemical compounds in air. It has seen widespread use in atmospheric monitoring and food science and shows increasing promise in applications such as industrial process monitoring, medical science and in crime and security scenarios. Written by leading researchers, this is the first book devoted to PTR-MS and it provides a comprehensive account of the basic principles, the experimental technique and various applications, thus making this book essential reading for researchers, technicians, postgraduate students and professionals in industry. The book contains nine chapters and is divided into two parts. The first part describes the underlying principles of the PTR-MS technique, including • the relevant ion-molecule chemistry • thermodynamics and reaction kinetics • a discussion of ion sources, drift tubes and mass spectrometers • practical aspects of PTR-MS, including calibration. The second part of the book turns its attention to some of the many applications of PTR-MS, demonstrating the scope and benefits, as well as the limitations, of the technique. The chapters that make up the second part of the book build upon the material presented in the first part and are essentially self-contained reviews focusing on the following topics: • environmental science • food science • medicine • homeland security, and • applications of PTR-MS in liquid analysis.

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.
