Download or read book Iodotrifluoromethane written by National Research Council and published by National Academies Press. This book was released on 2004-12-23 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military is considering using a compound called iodotrifluoromethane (CF3I) for fire suppression to replace previously-used compounds (halons) that are being phased out because they deplete the ozone layer. This report reviews available toxicological data on CF3I and evaluates the scientific basis of the U.S. Army's proposed exposure limit of 2,000 parts per million (ppm). The report recommends that CF3I be used for fire suppression in normally unoccupied spaces because of its potential to cause cardiac sensitization in test animals. The report also recommends that further genotoxicity testing be conducted (testing for changes in genetic material), and that CF3I be assessed for its potential to cause cancer. Should the Army decide to use CF3I, information should be collected and evaluated on how much of the chemical or any of its degradation products might be released and how often.

Download or read book Comprehensive Organic Functional Group Transformations written by Alan R. Katritzky and published by Elsevier. This book was released on 2003-03-21 with total page 964 pages. Available in PDF, EPUB and Kindle. Book excerpt: A vast range of different functional groups is potentially available from the attachment of three or four heteroatoms to carbon. Some of these are abundantly represented in the literature, others are rare, and many have yet to be described. The aim of this volume is to describe the synthesis of examples of known functional groups and to highlight those that are little known or unknown. All possible combinations of heteroatoms have been surveyed, with the exception of complexes in which carbon atoms are bonded only to transition elements. The material is organised in four parts: tetracoordinated carbon atoms bearing three attached heteroatoms are covered in Part 1, and those bearing four heteroatoms in Part II; the synthesis of tricoordinated carbon atoms with three attached heteroatoms is described in Part III; stabilized radicals and carbocations with three attached heteroatoms are covered briefly in Part IV.

Download or read book Gas Uptake Kinetics of Bromotrifluoromethane Halon 1301 and Its Proposed Replacement Iodotrifluoromethane CF3I written by and published by . This book was released on 1994 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A physiologically based simulation approach was used to estimate in vivo metabolic constants in male Fischer 344 rats for the two chemicals, bromotrifluoromethane (Halon 1301), and its proposed replacement candidate, iodotrifluoromethane (CF3I). A closed recirculating exposure system was used to collect a series of gas uptake curves for both chemicals at equivalent initial exposure concentrations. Additionally, tissue:air partitiOn coefficients were determined experimentally for each chemical and incorporated into a physiologically based pharmacokinetic model, which was then used to simulate the uptake of the chemicals. By iteratively adjusting the constants describing metabolism of the chemical, and optimized fit of the series of uptake curves was obtained for each chemical. This simulation approach adequately described the overall uptake of each chemical from the chamber. Given the relatively low level of partitioning of these chemicals into tissues and their relative inertness, this approach could not be used with certainty to discriminate between metabolism by saturable and/or first-order process and no metabolism at all.

Download or read book Twenty Years of Ozone Decline written by Christos Zerefos and published by Springer Science & Business Media. This book was released on 2009-05-24 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homer speaks of lightning bolts after which ‘a grim reek of sulphur bursts forth’ and the air was ‘?lled with reeking brimstone’. (Homer 3000 BC). The odour was not actually the smell of sulphur dioxide associated with burning sulphur, but rather was the ?rst recorded detection of the presence of another strong odour, that of ozone (O ) in Earth’s atmosphere. These molecules were formed by the passage of 3 lightning through the air, created by splitting the abundant molecular oxygen (O ) 2 molecules into two, followed by the addition of each of the free O atoms to another O to form the triatomic product. In fact, most of the ozone molecules present 2 in the atmosphere at any time have been made by this same two-step splitti- plus-combination process, although the initiating cause usually begins with very energetic solar ultraviolet (UV) radiation rather than lightning. Many thousands of years later, the modern history of ozone began with its synthesis in the laboratory of H. F. Schonbein in 1840 (Nolte 1999), although the positive con?rmation of its three-oxygen atom chemical formula came along sometime later. Scienti?c interest in high-altitude stratospheric ozone dates back to 1881 when Hartley measured the spectrum of ozone in the laboratory and found that its ability to absorb UV light extended only to 293nm at the long wavelength end (Hartley 1881a).
