Interest in the occurrence and behaviour of volatile organic compounds (VOCs) is increasing due to their adverse effects on the environment and human health. It is essential that information is made available on the various aspects of research on VOCs to enable better understanding and control of the various environmental and human health threats. The information in this book will be used to improve communication and understanding of the various approaches. In particular the potential and limitations of the described analytical methods will be essential in defining environmental studies and interpreting the results.

In the early 1980s, two water-supply systems on the Marine Corps Base Camp Lejeune in North Carolina were found to be contaminated with the industrial solvents trichloroethylene (TCE) and perchloroethylene (PCE). The water systems were supplied by the Tarawa Terrace and Hadnot Point watertreatment plants, which served enlisted-family housing, barracks for unmarried service personnel, base administrative offices, schools, and recreational areas. The Hadnot Point water system also served the base hospital and an industrial area and supplied water to housing on the Holcomb Boulevard water system (full-time until 1972 and periodically thereafter). This book examines what is known about the contamination of the water supplies at Camp Lejeune and whether the contamination can be linked to any adverse health outcomes in former residents and workers at the base.

Volatile Organic Compounds (VOCs) have anthropogenic and biogenic origins. At the Earth's scale, the natural sources represent a great part of the total VOCs present in the atmosphere but in industrialised regions, anthropogenic ones become the majority due to the various human activities related mainly to chemical industries (liquid fuels, solvents, thinners, detergents, degreasers, cleaners and lubricants). Almost all VOCs have effects on human health and many of them are even carcinogenic. It is also known that the VOCs can affect the central nervous system and may have mutagenic effects. Apart from human health, they also play an important role towards the environment, especially in the atmospheric pollution processes. Indeed, VOCs emissions lead to the promotion of photochemical reactions in the atmosphere (ozone formation, depletion of the stratospheric ozone layer and formation of photochemical smog). The present book gathers and presents some current research from across the world conducted by scientific experts in their fields. In seven valuable contributions, it deals with the emission and the environmental impact as well as the control of the Volatile Organic Compounds.

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.

With the quality of indoor air ranking highly in our lives, this second, completely, revised edition now includes 12 completely new chapters addressing both chemical and analytical aspects of organic pollutants. Sources of indoor air pollutants, measurement and detection as well as evaluation are covered filling the gap in the literature caused by this topical subject. This book is divided into four clearly defined parts: measuring organic indoor pollutants, investigation concepts and quality guidelines, field studies, and emission studies. The authors cover physico-chemical fundamentals of organic pollutants, relevant definitions and terminology, emission sources, sampling techniques and instrumentation, exposure assessment as well as methods for control. Test methods and studies for various indoor environments are described, such as automobile interiors, museum environments, or rooms with air ventilation. Emission sources covered include household and consumer products as well as electronic devices and office equipment. The book is aimed at chemists, physicists, biologists, and medical doctors at universities and research facilities, in industry and environmental laboratories as well as regulative bodies.

Controlling the emission of volatile organic compounds (VOC) became a very prominent environmental issue with the passage of the 1990 Clean Air Act Amendments, and will continue to be an environmental priority through the next decade. No single technology has played as important a role in the control of VOC emissions as thermal oxidation. It has the ability to destroy VOCs in a one-step process that produces innocuous by-products. Design of Thermal Oxidation Systems for Volatile Organic Compounds provides all the information needed for developing a thermal oxidation design in a single reference. It covers design, operation, and maintenance as well as the principles behind the classification of volatile organic compounds as hazardous waste. The author explores the primary purpose of thermal oxidizers and discusses their limitations. The book provides: practical, complete, and concise thermal oxidizer design principles an outline of state-of-the-art design principles a practical rather than theoretical approach real industrial examples in each chapter With the new regulations that affect VOC emissions, engineers from such diverse fields as oil refining, chemical distillation and separation processes, and pharmaceutical industries will need to design and implement thermal oxidation systems. Design of Thermal Oxidation Systems for Volatile Organic Compounds provides a reference to the entire design process, from conceptualization to operation and maintenance.

"Coming to a conclusion, this wonderful, informative and very interesting book presents an excellent overview of small volatile organic compounds and their role in our life and environment. Really fascinating is the entirety of scientific disciplines which were addressed by this book." –Flavour and Fragrance Journal, 2011 "... this book deserves to be a well-used reference in the library of any laboratory specialising in VOC". –Chemistry World, 2011 Volatile compounds are molecules with a relatively low molecular weight allowing for an efficient evaporation into the air. They are found in many areas of our everyday-life: they are responsible for the communication between species such as plants, insects or mammals; they serve as flavours or fragrances in many food products or perfumed consumer articles; and they play an important role in atmospheric chemistry. This book takes an interdisciplinary approach to volatile molecules. Review-style introductions to the main topics in volatile chemistry and biology are provided by international experts, building into a broad overview of this fascinating field. Topics covered include: The structural variety of volatile compounds Biogeneration of volatiles Synthesis of natural and non-natural volatiles Analysis of volatiles Volatile compounds as semiochemicals in plant-plant or plant-insect interactions Volatiles in pest control Pheromones and the influence of volatiles on mammals Olfaction and human perception Volatiles as fragrances The generation of flavours and food aroma compounds Stabilisation and controlled release of volatiles The impact of volatiles on the environment and the atmosphere
