Book Description
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.

Book Description
This book is the eighth volume in the series Acute Exposure Guideline Levels for Selected Airborne Chemicals, and reviews AEGLs for acrolein, carbon monoxide, 1,2-dichloroethene, ethylenimine, fluorine, hydrazine, peracetic acid, propylenimine, and sulfur dioxide for scientific accuracy, completeness, and consistency with the NRC guideline reports.

Book Description
With the narrative punch of Jonathan Harr’s A Civil Action and the commitment to environmental truth-telling of Erin Brockovich, The Fluoride Deception documents a powerful connection between big corporations, the U.S. military, and the historic reassurances of fluoride safety provided by the nation’s public health establishment. The Fluoride Deception reads like a thriller, but one supported by two hundred pages of source notes, years of investigative reporting, scores of scientist interviews, and archival research in places such as the newly opened files of the Manhattan Project and the Atomic Energy Commission. The book is nothing less than an exhumation of one of the great secret narratives of the industrial era: how a grim workplace poison and the most damaging environmental pollutant of the cold war was added to our drinking water and toothpaste.

Book Description
Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Chemicals contains a detailed and comprehensive methodology for developing acute exposure guideline levels (AEGLs) for toxic substances from inhalation exposures. The book provides guidance on what documents and databases to use, toxicity endpoints that need to be evaluated, dosimetry corrections from animal to human exposures, selection of appropriate uncertainty factors to address the variability between animals and humans and within the human population, selection of modifying factors to address data deficiencies, time scaling, and quantitative cancer risk assessment. It also contains an example of a summary of a technical support document and an example of AEGL derivation. This book will be useful to persons in the derivation of levels from other exposure routesâ€"both oral and dermalâ€"as well as risk assessors in the government, academe, and private industry.

Book Description
This toxicological profile succinctly characterizes the toxicologic and adverse health effects information for fluorides, hydrogen fluoride, and fluorine. Fluorides are often added to drinking water supplies and a variety of dental compounds. Some fluoride compounds are also used in the production of glass and enamel and in the steel industry. Fluorine gas is used primarily to make chemical compounds used in separating isotopes of uranium for use in nuclear reactors and nuclear weapons. Hydrogen fluoride is used in the manufacture of fluorocarbons, which are used as refrigerants, solvents, and aerosols. This profile includes: (A) The examination, summary, and interpretation of available toxicologic information and epidemiologic evaluations on fluorides, hydrogen fluoride, and fluorine to ascertain the levels of significant human exposure for the substance and the associated acute, subacute, and chronic health effects; (B) A determination of whether adequate information on the health effects of fluorides, hydrogen fluoride, and fluorine is available or in the process of development to determine levels of exposure that present a significant risk to human health of acute, subacute, and chronic health effects; and (C) Where appropriate, identification of toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans. Tables and figures. This is a print on demand edition of a hard to find publication.

Book Description
This book describes in detail various aspects of fluoride toxicity in animals. Animals, like human beings, suffer from the toxic effects of excess fluoride intake. They show pathological changes in their teeth and bone, together with a marked reduction in appetite, productive and reproductive potentials, which can result in severe economic losses in the dairy industry. Laboratory and wild animals also suffer from this ailment. Animal suffering and economic losses alike can be minimized through early diagnosis of the problem and by adopting suitable preventive and therapeutic measures. The book details the susceptibility of different animal species, important sources of toxicity, clinical signs and symptoms, pathophysiology, diagnostic methods, preventive and therapeutic approaches. It offers a valuable resource for scientists working in the fields of toxicology, veterinary science, animal nutrition, and environmental science, as well as for public health workers, animal welfare activists, public health veterinarians, field veterinarians, medical professionals and all others interested in the subject.
