Download or read book Fluoride in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2007-01-22 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.

Download or read book Fluorine and Health written by Alain Tressaud and published by Elsevier. This book was released on 2008-06-06 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorine and Health presents a critical multidisciplinary overview on the contribution of fluorinated compounds to resolve the important global issue of medicinal monitoring and health care. The involved subjects are organized in three thematic parts devoted to Molecular Imaging, Biomedical Materials and Pharmaceuticals. Initially the key-position of partially fluorinated low molecular weight compounds labelled either with the natural 19F-isotope for Magnetic Resonance Imaging (MRI) or labelled with the radioactive [18F]-isotope for Positron Emission Tomography (PET) is highlighted. Both non-invasive methods belong to the most challenging in vivo imaging techniques in oncology, neurology and in cardiology for the diagnosis of diseases having the highest mortality in the industrialized countries. The manifold facets of fluorinated biomaterials range from inorganic ceramics to perfluorinated organic molecules. Liquid perfluorocarbons are suitable for oxygen transport and as potential respiratory gas carriers, while fluorinated polymers are connected to the pathology of blood vessels. Another important issue concerns the application of highly fluorinated liquids in ophthalmology. Moreover, fluorine is an essential trace element in bone mineral, dentine and tooth enamel and is applied for the prophylaxis and treatment of dental caries. The various origins of human exposure to fluoride species is detailed to promote a better understanding of the effect of fluoride species on living organisms.Medicinally relevant fluorinated molecules and their interactions with native proteins are the main focus of the third part. New molecules fluorinated in strategic position are crucial for the development of pharmaceuticals with desired action and optimal pharmacological profile. Among the hundreds of marketed active drug components there are more than 150 fluorinated compounds. The chapters will illustrate how the presence of fluorine atoms alters properties of bioactive compounds at various biochemical steps, and possibly facilitate its emergence as pharmaceuticals. Finally the synthetic potential of a fluorinase, the first C-F bond forming enzyme, is summarized. - New approach of topics involving chemistry, biology and medicinal techniques - Transdisciplinar papers on fluoride products - Importance of fluoride products in health - Updated data on specific topics

Download or read book The Chemical Works of Carl Wilhelm Scheele written by Anders Lennartson and published by Springer. This book was released on 2017-05-08 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief draws on the first modern book about Carl Wilhelm Scheele which was published in Swedish in 2015. Following an introduction and bibliography of Scheele’s published works, the author analyses Scheele’s publications paragraph by paragraph, explaining the procedures and the results in modern terms, and summarising and elucidating Scheele’s conclusions. Up until now the original works by Scheele have only in part been translated into English, and to get a complete view of Scheele’s work, knowledge of both Swedish and German was required. This brief opens up the important work of Carl Wilhelm Scheele to an international audience of historians of chemistry, students of history of chemistry and interested chemists.

Download or read book Fluoride in Drinking water written by John Kirtley Fawell and published by World Health Organization. This book was released on 2006 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluoride is known to occur at elevated concentration in a number of parts of the world, where it can be a significant cause of disease. The primary focus of this book is the prevention of adverse health effects from excessive levels of fluoride in drinking water. The book fills the urgent need, identified for updating the WHO Guidelines for Drinking-water Quality, for information on the occurrence of fluoride, its health effects, ways of reducing excess levels, and methods for analysis of fluoride in water. The draft document, produced by a working group of experts convened to consider protection from fluoride and its control, was issued for extensive review and consultation. The resultant book, which incorporates the comments received, was further peer reviewed by experts in developed and developing countries. It is aimed at a wide range of individuals, including health workers and sanitary engineers who may require a broad introduction to the subject with more detailed guidance in some specific areas. Fluoride in Drinking-waterwill be an invaluable reference source for all those concerned with the management of drinking water containing fluoride and the health effects arising from its consumption, including water sector managers and practitioners, as well as health sector staff at policy and implementation levels. It will also be of interest to researchers, students, development workers, and consultants.

Download or read book Conservation of Wood Artifacts written by A. Unger and published by Springer Science & Business Media. This book was released on 2001-08-29 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this book was the desire to systematically organize the extant literature on the conservation of cultural property made of wood, from its beginnings before the Christian Era to the year 2000. Various published reviews and monographs, including Holzkonservierung (Wood Conserva tion) published by the senior author in 1988, have appeared over the years, especially in English and in German. They have provided exemplary treat merit of individual areas or aspects of wood conservation, but a comprehen sive, up-to-date exposition of historic and current developments has been lacking. The diverse professional fields of the authors, as well as their insights into methods of conservation and restoration of wood artifacts in Europe, North America, and Asia provided a solid basis for the success of this under taking. One of the goals during the examination of the literature was that not only well-known conservators and scientists from countries that are leaders in wood conservation should be represented, but that less well-known, often not as readily accessible contributions should also be included. Only in this manner was it possible to draw a comprehensive picture of the national and international state of wood conservation. The Art and Archaeology Technical Abstracts (AATA) of the Getty Institute were very helpful in our efforts to evaluate as many publications as possible.
