It is becoming increasingly important to understand how and why semivolatile atmospheric pollutants partition between gas phase and particulate matter in the atmosphere. In this text the world's leading researchers in the field explain the significance of gas/particle ratios; physical and chemical parameters determining how semivolatiles partition in the atmosphere; how gas/particle ratio measurements are made; what artefacts occur during sampling; and novel new techniques and instruments for obtaining artefact-free results. Intended to be a reference book and a guide for those who study the gas/particle ratios of semivolatile atmospheric compounds. This book will be of interest to beginners in the field as well as those who have been involved in the field for many years and would like, in a single reference text, a comprehensive compendium of what is known about the theory and practice of gas/particle phase measurements.

Here is the most comprehensive and up-to-date treatment of one of the hottest areas of chemical research. The treatment of fundamental kinetics and photochemistry will be highly useful to chemistry students and their instructors at the graduate level, as well as postdoctoral fellows entering this new, exciting, and well-funded field with a Ph.D. in a related discipline (e.g., analytical, organic, or physical chemistry, chemical physics, etc.). Chemistry of the Upper and Lower Atmosphere provides postgraduate researchers and teachers with a uniquely detailed, comprehensive, and authoritative resource. The text bridges the "gap" between the fundamental chemistry of the earth's atmosphere and "real world" examples of its application to the development of sound scientific risk assessments and associated risk management control strategies for both tropospheric and stratospheric pollutants. - Serves as a graduate textbook and "must have" reference for all atmospheric scientists - Provides more than 5000 references to the literature through the end of 1998 - Presents tables of new actinic flux data for the troposphere and stratospher (0-40km) - Summarizes kinetic and photochemical date for the troposphere and stratosphere - Features problems at the end of most chapters to enhance the book's use in teaching - Includes applications of the OZIPR box model with comprehensive chemistry for student use

Oxidation and removal of atmospheric constituents involve complex sequences of reactions which can lead to the production of photo-oxidants such as ozone. In order to understand and model these complex reaction sequences, it is necessary to have a comprehensive understanding of reaction mechanisms and accurate estimates of kinetic parameters for relevant gas-phase atmospheric reactions. This book presents recent advances in the field and includes the following topics: e.g. the oxidation of simple organic compounds, NOx kinetics and mechanisms, OH radical production and rate constants for the OH attack on more complex organic compounds, peroxy and alkoxy radical reactions, photo-oxidation of aromatic and biogenic compounds, and the interaction between radical species.

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.

Chemical Compounds in the Atmosphere deals with the chemistry of organic and inorganic compounds found in the atmosphere, including rare gases and compounds of oxygen and hydrogen, halogenated aromatic compounds, and organometallic compounds. The sources and concentrations of atmospheric trace gases are discussed, along with their chemical reactions and ultimate fates. The compounds are divided into groups on the basis of chemical constituent or chemical structure. Comprised of 10 chapters, this book opens with an overview of atmospheric composition and atmospheric chemistry, followed by a discussion on inorganic compounds present in the troposphere such as rare gases and compounds containing nitrogen, sulfur, and halogens. The next chapters focus on hydrocarbons such as alkanes, alkenes, and alkynes; carbonyl compounds such as ketones and aldehydes; oxygenated and nitrogen- and sulfur-containing organic compounds; organic halogenated compounds such as mercaptans and thiocyanates; and organometallic compounds such as organophosphorus pesticides. The final chapter is a synthesis of data on atmospheric compounds mentioned in this text, with emphasis on their occurrence, sources, oxidation, and lifetimes. The chemistry of acid rain is also considered. This monograph will be of value to those engaged in atmospheric measurements, theoretical and laboratory studies of chemical parameters relevant to the atmosphere, and air quality assessments.

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.
