Available in PDF, EPUB and Kindle. Book excerpt: 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.
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.

Download or read book cotoxicochimie des hydrocarbures written by PICOT André and published by Lavoisier. This book was released on 2013-04-15 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’écotoxicochimie, est une nouvelle branche de l’écologie qui se propose d’aborder les atteintes néfastes des produits chimiques sur l’environnement et la santé, à partir des données récentes de la chimie et de la biologie, en s’appuyant sur la toxicochimie, discipline d’interface élaborée en 1979. Les hydrocarbures, famille de base des composés organiques, ont été sélectionnés comme première approche dans Écotoxicochimie – Applications aux hydrocarbures. Ces produits chimiques sont à l’origine de la carbochimie et de la pétrochimie et leur prise en compte a permis de jeter les bases d’une prévention des risques aussi bien toxicochimiques qu’écotoxicochimiques. Risques liés en particulier à toutes les pollutions hydrocarbonées qui devraient être beaucoup mieux encadrées, tant en milieu domestique que dans les milieux de travail ou dans l’environnement. Ainsi ces hydrocarbures sont impliqués dans des pollutions maritimes retentissantes, qui restent malheureusement toujours d’actualité. Si les pollutions engendrées par l’exploitation maritime du pétrole sont également très inquiétantes, un autre sujet apparaît de plus en plus préoccupant avec l’extraction du gaz et des huiles de schiste, dont la technique mise en œuvre faisant appel à la fracturation hydraulique horizontale, est constituée d’un véritable cocktail chimique à faire frémir bien des toxicologues avertis… Sans précédent dans la littérature scientifique, toutes les propriétés toxiques des composés les plus utilisés sont présentées clairement dans cet ouvrage, à partir des références bibliographiques les plus actualisées. En tant que chimistes, spécialistes en toxicochimie, soucieux de comprendre pourquoi certains produits chimiques peuvent être dangereux pour la santé et l’environnement, les auteurs André Picot et Frédéric Montandon associés à plusieurs autres spécialistes, présentent, à la fin de l’ouvrage, une approche préventive, basée sur la sélection de produits de substitution notamment pour les solvants organiques. Trente-quatre fiches résumées dites de ToxicoÉcotoxicoChimie (FRTEC) devraient permettre de faire le bon choix parmi les principaux hydrocarbures couramment utilisés, en particulier comme solvants, et ceci dans de multiples disciplines. Par son approche novatrice, cet ouvrage sera indispensable aux professionnels des industries, des PMI et PME de tous les domaines traitant ou utilisant les hydrocarbures ou leurs dérivés, mais aussi aux responsables de santé publique ou des milieux de travail, aux organisations gouvernementales et non gouvernementales, et aux écologistes de tous horizons… sans oublier les enseignants et étudiants en chimie, en biologie et en écologie désireux de mieux comprendre pourquoi la chimie est à la base de la vie, qu’il nous faut protéger au mieux.
Download or read book Plant Volatile Analysis written by Hans F. Linskens and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods of Plant Analysis When the handbook Modern Methods ofPlant Analysis, was first introduced in 1954, the considerations were: 1. the dependence of scientific progress in biologyon the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete, that it is difficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods ofPlant Analysis.It is hoped that the NewSeries willbejust as acceptable to those working in plant sciences and related fields as the early volumes undoubtedlywere.It is difficult to single out the major reasons for the success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a waythat made description, as applied to plant material, complete in itselfwith little need to consult other publications. Contribution authors have attempted to follow these guidelines in this New Series of volumes. Editorial The earlier series of Modern Methods ofPlant Analysis was initiated by Michel V.

Available in PDF, EPUB and Kindle. Book excerpt: "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

Available in PDF, EPUB and Kindle. Book excerpt: La microélectronique est un monde complexe dans lequel plusieurs sciences comme la physique, l’électronique, l’optique ou la mécanique, contribuent à créer des nano-objets fonctionnels. La chimie est particulièrement impliquée dans de nombreux domaines tels que la synthèse des matériaux, la pureté des fluides, des gaz, des sels, le suivi des réactions chimiques et de leurs équilibres ainsi que la préparation de surfaces optimisées et la gravure sélective de couches spécifiques. Au cours des dernières décennies, la taille des transistors s’est considérablement réduite et la fonctionnalité des circuits électroniques s’est accrue. Cette évolution a conduit à une interpénétration de la chimie et de la microélectronique exposée dans cet ouvrage. Chimie en microélectronique présente les chimies et les séquences utilisées lors des procédés de production de la microélectronique, des nettoyages jusqu’aux gravures des plaquettes de silicium, du rôle et de l’impact de leur niveau de pureté jusqu’aux procédés d’interconnexion des millions de transistors composant un circuit électronique. Afin d’illustrer la convergence avec le domaine de la santé, l’ouvrage expose les nouvelles fonctionnalisations spécifiques, tels que les capteurs biologiques ou les capteurs sur la personne.
