Available in PDF, EPUB and Kindle. Book excerpt: "Fluoride has been added to public drinking water in Canadian communities since the 1940s as a means of preventing tooth decay. Dental fluorosis is a known adverse effect of excessive fluoride exposure during tooth formation. Fluorosis ranges from barely noticeable whitish striations in the enamel to severe pitting and brownish staining. In general, the prevalence of dental fluorosis in communities with water fluoridation is higher in comparison to non-water fluoridated communities. No evidence was found for an association between water fluoridation and any of the following adverse outcomes: bone mineral density, bone fractures, bone cancer, or cancer in other body tissues. The best available evidence supports the finding that water fluoridation reduces the prevalence of dental caries, although this benefit of fluoridation may be limited due to multiple sources of exposures to fluoride that are now available to the public. Although many major health organizations support water fluoridation, the trend across Canadian communities has been a decreasing uptake in water fluoridation or discontinuation"--Page 1.

Download or read book Acid Deposition Environmental Economic and Policy Issues written by Donald Adams and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about acid deposition, commonly referred to as acid rain, as a widespread pollution problem with severe ecological consequences has heightened public awareness. Many authorities fear that acid deposition may be the worst environmental crisis of our industrialized society because of both the global implications and possible widespread, irreversible damage to lakes, soils, and forested ecosystems. Neither state nor international boundaries are exempt from the transport and deposition of airborne pollutants resulting from local and distant emission sources. The dilemma and debate will continue as long as society requires fossil fuels for its energy needs without regard to emission constraints. This book started as a modest attempt to provide a status report on atmospheric transport, the chemical processes which produce acidifying agents, and resultant ecological and economic consequences. The materials in this book have been substantially revised from those presented at the conference in 1983. It became obvious that additional chapters were required when sudden and profound changes occurring in European forests were reported. It is felt that perhaps such damages could be an early warning to forested ecosystems in the northeastern United States and Canada as well as other places throughout the world. Most importantly, it is essential that gained scientific knowledge be translated into required legislation - a section on Policy Issues was incorporated to address these concerns. It is hoped that the reader will become informed and concerned enough to be involved in ll this IIglobal debate. Donald D. Adams Halter P.
Download or read book The Oxidation of Oxygen and Related Chemistry written by Neil Bartlett and published by World Scientific. This book was released on 2001 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: The selected papers in this invaluable volume are arranged in chapters, each with an introductory essay. The purpose of the arrangement is to illustrate the process of scientific discovery at work. Neil Bartlett's field is that of powerful oxidizers. The early chapters tell the story of the oxidation of the oxygen molecule and the discovery of xenon chemistry. His work in noble-gas chemistry is summarized. Succeeding chapters show how metastable fluorides such as Ag3 and NiF4 came to be prepared at ordinary temperatures and pressures, and how they have provided the most potent oxidizers and fluorinators ever prepared.
