Water fluoridation

Water fluoridation is artificial addition of fluorine compounds in the water to enhance the content of fluorine to hygienic norms. Is carried out at low fluoride content in drinking water. Insufficient intake of fluoride in drinking water in the body leads to increased morbidity of population by dental caries and some other disorders. Fluoridation of water allows to reduce morbidity of dental caries by 20-40%. However, a significant increase in the concentration of fluoride in drinking water can lead to a number of painful disorders in humans, including the fluorosis (see). In this regard, the fluoridation of water is carried out according to certain conditions and under strict sanitary control. The content of fluoride in the water fluoridation lead in drinking water is usually up to 1 mg/l, and in hot days in connection with increase of water consumption up to 0.6 mg/L. as of fluorine-containing reagents are mainly used fluoride and kremneftoristogo sodium in dry form and in the form of solution (the batching accuracy of ±0.5%). Sanitary-hygienic monitoring of water fluoridation should be conducted systematically by laboratory tests of water samples (the concentration of fluoride in fluoridated water) and by daily mapping of consumption of fluorine-containing chemicals by quantity of fluorinated water for water supply facilities.
