Book Synopsis Reactive Halogen Compounds in the Atmosphere by : Peter Fabian
Download or read book Reactive Halogen Compounds in the Atmosphere written by Peter Fabian and published by Springer. This book was released on 1999 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific evidence clearly shows that chlorine and bromine compounds, such as CFCs, released into the atmosphere are responsible for continuous and progressive global ozone losses superimposed by dramatic seasonal ozone depletions first observed over Antarctica, now occurring over Arctic regions as well. Today substitutes are produced and emitted, some of which are highly reactive substances. This handbook volume deals with these reactive halogen compounds and their interactions. It provides a review on the present knowledge of their properties, applications, sources, sinks as well as international regulations.
Book Synopsis Halogens and Noble Gases, Second Edition by : Monica Halka
Download or read book Halogens and Noble Gases, Second Edition written by Monica Halka and published by Infobase Holdings, Inc. This book was released on 2019-12-01 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of their adjacency in the periodic table, halogens and nonmetals have very different properties. Halogens are among the most chemically reactive elements in the periodic table, exhibiting a diverse chemistry in terms of the large numbers of compounds they can form. On the other hand, noble gases are the least chemically reactive elements. In fact, before the 1960s, chemists referred to these elements as inert gases, because it was believed that they exhibited no chemistry whatsoever. Providing the basics of these elements, including their role in history and some of the important scientists involved in their discovery, this newly updated, full-color resource features up-to-date scientific understanding in a clear and accessible format. Halogens and Noble Gases, Second Edition examines the ways humans use halogens and noble gases and the resulting benefits and challenges to society, health, and the environment. Fluorine, chlorine, bromine, iodine, helium, and krypton are covered in this eBook, along with the fundamentals of chemistry and physics as well as possible future developments in halogen and noble gas science and its applications.

Download or read book Satellite Observations of Atmospheric Halogen Oxides written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The important role of halogen compounds in atmospheric ozone destruction became obvious after dramatic ozone loss was observed over Antarctica in the mid 1980s, usually referred to as?ozone hole?. In the following years reactive halogen species were also discovered in the troposphere. Since the discovery of the ozone hole the understanding of the atmospheric halogen chemistry was largely extended, in particular by spectroscopic measurements of BrO and OClO which both show characteristic absorption features in the UV spectral range. These measurements were performed from ground based and air borne instruments and thus could only provide?snapshots? of the atmospheric conditions. In this PhD thesis algorithms for the analysis of atmospheric BrO and OClO from the GOME (Global Ozone Monitoring Experiment) instrument aboard the European research satellite ERS-2 were developed. It was possible to monitor the spatial and temporal evolution of atmospheric BrO and OClO on a global scale. In particular, enhanced BrO concentrations in the boundary layer were first detected from satellite. In addition, strong evidence for the presence of BrO in the free troposphere was found. From the GOME OClO measurements it was possible to study stratospheric chlorine activation in both hemispheres with respect to their temporal evolution and strength.
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 Ocean-Atmosphere Interactions of Gases and Particles by : Peter S. Liss
Download or read book Ocean-Atmosphere Interactions of Gases and Particles written by Peter S. Liss and published by Springer. This book was released on 2013-12-18 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oceans and atmosphere interact through various processes, including the transfer of momentum, heat, gases and particles. In this book leading international experts come together to provide a state-of-the-art account of these exchanges and their role in the Earth-system, with particular focus on gases and particles. Chapters in the book cover: i) the ocean-atmosphere exchange of short-lived trace gases; ii) mechanisms and models of interfacial exchange (including transfer velocity parameterisations); iii) ocean-atmosphere exchange of the greenhouse gases carbon dioxide, methane and nitrous oxide; iv) ocean atmosphere exchange of particles and v) current and future data collection and synthesis efforts. The scope of the book extends to the biogeochemical responses to emitted / deposited material and interactions and feedbacks in the wider Earth-system context. This work constitutes a highly detailed synthesis and reference; of interest to higher-level university students (Masters, PhD) and researchers in ocean-atmosphere interactions and related fields (Earth-system science, marine / atmospheric biogeochemistry / climate). Production of this book was supported and funded by the EU COST Action 735 and coordinated by the International SOLAS (Surface Ocean- Lower Atmosphere Study) project office.

Book Synopsis Naturally Occurring Organohalogen Compounds by : A. Douglas Kinghorn
Download or read book Naturally Occurring Organohalogen Compounds written by A. Douglas Kinghorn and published by Springer Nature. This book was released on 2023-07-24 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume is the third in a trilogy that documents naturally occurring organohalogen compounds, bringing the total number — from fewer than 25 in 1968 — to approximately 8,000 compounds to date. Nearly all of these natural products contain chlorine or bromine, with a few containing iodine and, fewer still, fluorine. Produced by ubiquitous marine (algae, sponges, corals, bryozoa, nudibranchs, fungi, bacteria) and terrestrial organisms (plants, fungi, bacteria, insects, higher animals) and universal abiotic processes (volcanos, forest fires, geothermal events), organohalogens pervade the global ecosystem. Newly identified extraterrestrial sources are also documented. In addition to chemical structures, biological activity, biohalogenation, biodegradation, natural function, and future outlook are presented.
Book Synopsis Natural Production of Organohalogen Compounds by : Gordon W. Gribble
Download or read book Natural Production of Organohalogen Compounds written by Gordon W. Gribble and published by Springer. This book was released on 2005-07-25 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the state-of-the-art knowledge on naturally occurring organohalogens, of which more than 3700 are documented. The chapters cover all aspects of this field, including the structural diversity and sources of organohalogens, the mechanisms for their formation and biodegradation, the clinical use of dichloroacetate, and the synthesis of the powerful anticancer chlorine-containing cryptophycin. Both biogenic and abiogenic sources of organohalogens are treated, the latter of which include volcanic emissions and abiogenic formation in soil. Halogenation in humans, fungi, and in the ocean are covered in separate chapters. Sources and biosynthesis of the relatively rare natural organofluorines are also discussed in this volume. By better understanding of the role nature plays in the area of organohalogens, we can more intelligently regulate the production, use, and disposal of man-made organohalogen compounds.
Book Synopsis Mercury Fate and Transport in the Global Atmosphere by : Nicola Pirrone
Download or read book Mercury Fate and Transport in the Global Atmosphere written by Nicola Pirrone and published by Springer Science & Business Media. This book was released on 2009-06-15 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury, primarily because of its existence and bioaccumulation as methylmercury in aquatic organisms, is a concern for the health of higher trophic level organisms, or to their consumers. This is the major factor driving current research in mercury globally and in environmental regulation, and is the driver for the current UNEP Global Partnership for Mercury Transport and Fate Research (UNEP F&T) initiative. The overall focus of the UNEP F&T report is to assess the relative importance of different processes/mechanisms affecting the transfer of mercury (Hg) from emission sources to aquatic and terrestrial receptors and provide possible source-receptor relationships. This transfer occurs through atmospheric transport, chemical transformations and subsequent deposition, and involves the intermittent recycling between reservoirs that occurs prior to ultimate removal of Hg from the atmosphere. Understanding the sources, the global Hg transport and fate, and the impact of human activity on the biosphere, requires improved knowledge of Hg movement and transformation in the atmosphere. An improved understanding of Hg emission sources, fate and transport is important if there is to be a focused and concerted effort to set priorities and goals for Hg emission management and reduction at the national, regional and global levels; and to develop and implement such policies and strategies. To achieve this, a series of coordinated scientific endeavors focused on the estimation of sources, measurement and validation of concentrations and processes, and modeling, coupled with interpretation of the results within a policy framework, is likely to be required.
