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 Biogeochemistry of Forested Catchments in a Changing Environment by : Egbert Matzner
Download or read book Biogeochemistry of Forested Catchments in a Changing Environment written by Egbert Matzner and published by Springer Science & Business Media. This book was released on 2004-07-12 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stability of forest ecosystems is affected by changes of environment conditions, like by increasing temperatures, increasing atmospheric CO2 and decreasing deposition rates of nutrients and acidity. This volume integrates the results of long term interdisciplinary ecosystem research at two forested watersheds in Germany with special emphasis on the biogeochemistry of carbon, dissolved organic matter and mineral elements in response to changing environmental conditions and management. Despite the reduction in acidic deposition, forest ecosystems are still threatened by soil acidification, nutrient depletion and eutrophication and criteria of sustainability are not yet achieved. The results highlight the complex interactions between vegetation, animals and soils in terrestrial ecosystems that are triggered by changes in environmental conditions.
Download or read book Atmospheric Degradation written by and published by . This book was released on 2018-05 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Tropospheric Chemistry written by W. Seiler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation, transport and impact of photo-oxidants, e.g., ozone, is a major environmental problem in densely populated areas with corresponding high emissions of ozone precursor substances such as NOx and volatile organic carbon compounds (VOC). Although major progress has been achieved within the last decade, there are still significant uncertainties in our understanding of the chemical behavior of the polluted atmosphere, in particular the interaction between cities and surrounding areas as well as the contribution of pollution to the global changes, e.g., the oxidation capacity of the troposphere. This book focuses on specific issues related to the chemistry of polluted atmospheres. The main issues cover areas such as modelling, emission inventories, chemical transformation as well as transport of pollutants on an urban/regional scale. The overall topic of the book is addressed in an interdisciplinary approach. The book is of specific interest for advanced researchers in tropospheric chemistry, from the PhD or post-doctoral levels and beyond.

Book Synopsis Introduction to Atmospheric Chemistry by : Daniel J. Jacob
Download or read book Introduction to Atmospheric Chemistry written by Daniel J. Jacob and published by Princeton University Press. This book was released on 1999 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric chemistry is one of the fastest growing fields in the earth sciences. Until now, however, there has been no book designed to help students capture the essence of the subject in a brief course of study. Daniel Jacob, a leading researcher and teacher in the field, addresses that problem by presenting the first textbook on atmospheric chemistry for a one-semester course. Based on the approach he developed in his class at Harvard, Jacob introduces students in clear and concise chapters to the fundamentals as well as the latest ideas and findings in the field. Jacob's aim is to show students how to use basic principles of physics and chemistry to describe a complex system such as the atmosphere. He also seeks to give students an overview of the current state of research and the work that led to this point. Jacob begins with atmospheric structure, design of simple models, atmospheric transport, and the continuity equation, and continues with geochemical cycles, the greenhouse effect, aerosols, stratospheric ozone, the oxidizing power of the atmosphere, smog, and acid rain. Each chapter concludes with a problem set based on recent scientific literature. This is a novel approach to problem-set writing, and one that successfully introduces students to the prevailing issues. This is a major contribution to a growing area of study and will be welcomed enthusiastically by students and teachers alike.

Available in PDF, EPUB and Kindle. Book excerpt: Prepared by an international team of eminent atmospheric scientists, Mechanisms of Atmospheric Oxidation of the Oxygenates is an authoritative source of information on the role of oxygenates in the chemistry of the atmosphere. The oxygenates, including the many different alcohols, ethers, aldehydes, ketones, acids, esters, and nitrogen-atom containing oxygenates, are of special interest today due to their increased use as alternative fuels and fuel additives. This book describes the physical properties of oxygenates, as well as the chemical and photochemical parameters that determine their reaction pathways in the atmosphere. Quantitative descriptions of the pathways of the oxygenates from release or formation in the atmosphere to final products are provided, as is a comprehensive review and evaluation of the extensive kinetic literature on the atmospheric chemistry of the different oxygenates and their many halogen-atom substituted analogues. This book will be of interest to modelers of atmospheric chemistry, environmental scientists and engineers, and air quality planning agencies as a useful input for development of realistic modules designed to simulate the atmospheric chemistry of the oxygenates, their major oxidation products, and their influence on ozone and other trace gases within the troposhere.

Download or read book Risks Associated with the Presence of Volatile Organic Compounds in the Environment and the Ranking of 18 Tributaries of the St. Lawrence River Upstream and Downstream of Montréal written by Mitchell Michael Sisak and published by St. Lawrence Centre. This book was released on 1994 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volatile organic compounds (VOC) are present in a variety of environments and originate mainly from two sources: industrial effluents and the chlorination of water. This report presents results from a study carried out to provide information on the distribution and relative importance of VOC in 18 tributaries located in and around the Montréal region. This region was selected for the study because of the known association between population centers and sources of VOC. The researchers sampled the tributaries for 20 compounds using headspace gas chromatography/mass spectrometry. The results include annual and daily load, by substance, and the contribution to the load from each tributary. The researchers also correlated VOC contributors with the Entraco potential toxic contribution index and the Chimiotox index. The report also discusses the effect of ice cover on the intercompartmental exchange of VOC.
