Endemic fluorosis is caused by excessive intake of fluorine in drinking water, air, food, tea and other media in a specific natural environment for a long time, which involves at least 25 countries, such as China, India, Vietnam, Iran, Egypt, Mexico, Argentina and influences more than 200 million of population. China and India are the countries with the most extensive endemic fluorosis and the most serious damages. There are three main intake sources of endemic fluorosis, e.g., drinking water, coal-burning pollution and drinking tea. Coal-burning type of endemic fluorosis was established in Guizhou Province of China in 1970’s. The residents in the areas used indoor stoves with no flue to burn coals with high content of fluoride to bake grains in the autumn and heat in the winter. This results in excessive intake of fluorine and then leads chronic poisoning. It has been confirmed that 13 provinces of China with 34.3 million of population are influenced by this type of fluorosis with severe injuries to most organs of human body. The content of this book covers the epidemiology, pathological changes, molecular pathogenesis and clinical treatments of the disease. This book is a suitable reference for the researchers and graduate students in this field, which is helpful to improve the understanding of this disease and to take preventive measures.

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.

In recent years, there have been significant advances in the techniques of sampling and analysis, which has allowed the more accurate recording of environmental levels of many substances present in the environment. At the same time, processes for the remediation of contaminated matrices have evolved, through the application and/or combination of biological, physical, and chemical procedures.The purpose of this book is to present new studies aimed at determining levels of environmental pollution in various parts of the world. It also shows new alternatives for the remediation of contaminated matrices.

Fluoride pollution is a problem in all industrialized countries. The topic of fluorides in medicine and agriculture, and fluoridation of public water supplies is one that has attracted much controversy. This book aims to review the research findings, and provide a comprehensive reference on the effects of fluorides on plants and animals. It also includes information on conducting field surveys, establishing air quality criteria and standards, and the problems associated with fluoride analysis in air, water, soil and vegetation.

Trace Elements in Coal focuses on the compositions, reactions, and properties of trace elements in coal. The book first discusses the origin of trace elements in coal. The formation of peat; geological and geochemical aspects of coal seams; geology of Australian coals; constitution of coal; history of trace elements in coal; and coal mining in Australia are discussed. The text also clarifies the mode of occurrence of trace elements in coal. The identification of minerals in coal; silicon-rich minerals; carbonate minerals; sulfide minerals; lignites and brown coals; and phosphates are discussed. The book then underscores the methods of analysis. Inductively coupled plasma atomic emission spectrometry; atomic absorption spectrometry; spark source mass spectrometry; and neuron activation analysis are described. The text also focuses on the contents of trace elements in coal; comparisons of coal with shale and soil; relationship of radioactivity and coal; and relevance of trace elements in coal. The book is a good source of data for readers wanting to study the trace elements in coal.

Fluorine is best known for its role in the prevention of cavities and in improving oral and bone health however equally there are millions of people around the world suffering from dental fluorosis due to chronic exposure to high levels of fluoride in drinking water. This volume, written by leading researchers in this area, examines the positives and negatives of fluorine and its effects on humans for example fluoride-induced oxidative stress in the liver, effects of fluoride on insulin and preventing fluoride toxicity. Extremely useful for underpinning cross-disciplinary fluorine research, this book provides a fascinating insight for those with an interest in the health and nutritional sciences.

"Dental fluorosis refers to changes in the appearance of tooth enamel that are caused by long-term ingestion of fluoride during the time teeth are forming. Studies conducted in the 1930s showed that the severity of tooth decay was lower and dental fluorosis was higher in areas with more fluoride in the drinking water. In response to these findings, community water fluoridation programs were developed to add fluoride to drinking water to reach an optimal level for preventing tooth decay, while limiting the chance of developing dental fluorosis. By the 1980s, studies in selected U.S. communities reported an increase in dental fluorosis, paralleling the expansion of water fluoridation and the increased availability of other sources of ingested fluoride, such as fluoride toothpaste (if swallowed) and fluoride supplements. This report describes the prevalence of dental fluorosis in the United States and changes in the prevalence and severity of dental fluorosis among adolescents between 1986-1987 and 1999-2004. Data from the National Health and Nutrition Examination Survey, 1999-2004 and the 1986-1987 National Survey of Oral Health in U.S. School Children." - p. 1.

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.
