Volatile Organic Compounds in the Atmosphere 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.

Atmospheric Degradation 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, practi

Review and Integration of Biosphere Atmosphere Modelling of Reactive Trace Gases and Volatile Aerosols Excerpt :

When considering biosphere–atmosphere exchange of trace gases and volatile aerosols, significant advances have been made both from an experimental and modelling point of view and on several scales. This was particularly stimulated by the availability of new datasets generated from improvements in analytical methods and flux measurement techniques. Recent research advances allow us, not only to identify major mechanisms and factors affecting the exchanges between the biosphere and the atmosphere, but also to recognize several gaps in the methodologies used in accounting for emissions and deposition in landscape and global scale models. This work aims at (i) reviewing exchange processes and modelling schemes, parameterisations and datasets, (ii) presenting a common conceptual framework to model soil-vegetation-atmosphere exchange of reactive trace gases and aerosols accounting for in-canopy transfer chemical interactions and (iii) discussing the key elements of the agreed framework.

Biogeochemistry of Forested Catchments in a Changing Environment 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.
