Book Description :

Earth's atmosphere holds a mass of organic compounds, which differ by orders of magnitude regarding fundamental properties such as volatility, reactivity, and propensity to form cloud droplets, affecting their impact on global climate and human health. Volatile organic compounds (VOCs) play a vital role in the chemistry of the atmosphere by impelling ozone and hydroxyl radical (OH) concentrations and the renovation rates of nitrogen oxides (NOx). Elevated levels of VOCs and NOx have led to an approximate doubling of ozone in the lower troposphere over the past couple of centuries, making tropospheric ozone the third most important anthropogenic greenhouse gas after carbon dioxide (CO2) and methane. Monitoring of volatile organic compounds (VOCs) is a key piece in understanding photochemical air quality in urban atmosphere. Anthropogenic sources such as incomplete combustion of organic substances, the use of petrochemical solvents, and vaporizations of petroleum products are sources of VOCs. Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. Therefore, their sources, sinks and dwelling times are the subject of current research. Atmospheric Degradation of Organic Substances describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyze gaseous and particulate organic compounds in the atmosphere. The book also includes evaluation of the relative ozone-forming potentials of the captured VOC species in the atmosphere of urban settlement. The analytical toolbox available for chemists to study atmospheric organic compounds has expanded considerably during the past decade, opening new windows into speciation, time resolution and detection of reactive and semi-volatile compounds at low concentrations. This has provided unprecedented opportunities, but also revealed new scientific challenges.This book is of interest to students, practitioners, as well as guiding tool for researchers in the field of atmospheric research.

Book Description :

Indoor Air Pollution has become a major topic in environmental research and health. Most people spend more than 80% of their time in buildings and are exposed to a broad range of pollutants from indoor sources such as building materials, furniture, carpets and textiles, heating and cooking, household and consumer products, etc. The volume provides a comprehensive review of the major indoor air pollutants: volatile organic compounds, biocides, indoor particles and fibres, combustion products and micro-organisms and their metabolites. Sources and sinks of air pollutants in indoor environments and their chemistry are distinctly different from ambient air pollution, even though the latter may influence indoor air quality. Adsorption and desorption processes, the pollutant source dynamics, gas phase reactions and kinetics - including the fate and final chemical destiny of chemically unstable intermediate compounds - are topics of scientific research as well as the evaluation of their sensory impact and irritation potential. Guidelines for assessing indoor pollution and a broad range of analytical methods have been recently developed and are reviewed by internationally renowned scientists. The specific characteristics of indoor air pollution in developing countries due to the widespread use of open fires for cooking, heating and lighting are analysed as well as the Chinese strategies to address the growing pollution problems by air pollution in its modern building stock.

Book Description :

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 Description :

From long-standing worries regarding the use of lead and asbestos to recent research into carcinogenic issues related to the use of plastics in construction, there is growing concern regarding the potential toxic effects of building materials on health. Toxicity of building materials provides an essential guide to this important problem and its solutions. Beginning with an overview of the material types and potential health hazards presented by building materials, the book goes on to consider key plastic materials. Materials responsible for formaldehyde and volatile organic compound emissions, as well as semi-volatile organic compounds, are then explored in depth, before a review of wood preservatives and mineral fibre-based building materials. Issues related to the use of radioactive materials and materials that release toxic fumes during burning are the focus of subsequent chapters, followed by discussion of the range of heavy metals, materials prone to mould growth, and antimicrobials. Finally, Toxicity of building materials concludes by considering the potential hazards posed by waste based/recycled building materials, and the toxicity of nanoparticles. With its distinguished editors and international team of expert contributors, Toxicity of building materials is an invaluable tool for all civil engineers, materials researchers, scientists and educators working in the field of building materials. Provides an essential guide to the potential toxic effects of building materials on health Comprehensively examines materials responsible for formaldehyde and volatile organic compound emissions, as well as semi-volatile organic compounds Later chapters focus on issues surrounding the use of radioactive materials and materials that release toxic fumes during burning

Book Description :

Individual exposure to air pollutants is determined by the behavior of indoor sources and sinks and activity patterns. This paper discusses a model that allows analysis of individual exposure for a wide range of sources and sinks. Emphasis of the discussion is on exposures to volatile organic compounds (VOCs) from commonly used sources. The effects of source and sink behavior on exposure are complex. Important factors include source strength, source decay rate, rates to the sink, re-emissions from the sink, and building operation parameters such as ventilation rate. Sources provide the primary exposure and dominate exposure while the source strength is strong. Sinks modify exposure by reducing peak concentrations and, because of re-emissions from sinks, by increasing the time of relatively high concentrations. Exposures from several different sources are analyzed both with and without sinks and under a range of different building operation scenarios. The need for standard scenarios in evaluating the effects of sources on individual exposure is discussed. Model concentration predictions are compared with data from an indoor air quality (IAQ) test house.

This volume contains the invited papers and a transcript of the final panel discussion in the First Scientific Conference of the International Global Atmospheric Chemistry (lGAC) Project, held in Eilat, Israel from April 18-22, 1993. The conference was hosted by the Israeli Institute for Biological Research (IIBR) and was the 37th in the prestigious OHOLO Conference series in Israel. The conference was devoted to the subject of "Global Atmospheric-Biospheric Chemistry" and was a landmark event in this area. It provided the first comprehensive report of progress under IGAC toward improving our understanding of the chemical and biological processes that determine the changing composition of the earth's atmosphere. This work is an essential component of the comprehensive International Geosphere Biosphere Program (lGBP) devoted to measuring and understanding global changes in the past and present, and predicting the future evolution of our planet. I want to devote this brief foreword to thanking several people who worked especially hard to make the conference a success and who helped to produce this volume as a record of the event. Paul Crutzen, Amram Golombek, Pamela Matson and Henning Rodhe did sterling service on the conference organizing committee. Special thanks go to Amram Golombek and Dr. Cohen, the Director of IIBR, who hosted the event in Israel. Anne Slinn did an excellent job in producing the Abstract book and helping with administrative matters. Alex Pszenny helped capably to critically review the Abstracts.

Book Description :

This volume addresses a broad spectrum of the environmental issues surrounding organic bromine and iodine compounds. It covers their partition among the environmental compartments and the potential for their long-range dissemination. The important issue of their atmospheric chemistry is discussed in detail in the context of ozone depletion and global warming, and the significant difference between the reactions of methyl bromide and methyl iodide are underscored. The mammalian toxicity is discussed and the mechanisms of the degradation and transformation of organic bromine and iodine compounds addressed. There has been considerable interest in naturally occurring metabolites in the current debate on the fate and partition of methyl bromide that is an important fungicide and is produced in substantial quantities as a metabolite of marine algae. The possible natural occurrence of diphenyl ethers that are used as flame retardants have also been raised. A discussion is given on plausible mechanisms for the biosynthesis of representative organic bromine and organic iodine metabolites. Reaction pathways are illustrated throughout and comprehensive references are given.
