83FLUORIDE IN TRIBAL BELT OF SARGUJA DISTRICTHigh concentrations of fluoride (F–) in drinking water are harmful to human health. This communication reports F– incidence in groundwater and its relation with the prevalence of dental and skeletal fluorosis in Ambikapur, Sarguja District, Chhattisgarh, India. In 1994 a World Health Organization expert committee on fluoride use stated that 1.0 mg/L should be an absolute upper bound, even in cold climates, and that 0.5 mg/L may be an appropriate lower limit A 2007 Australian systematic review recommended a range from 0.6 to 1.1 mg/L Assay of fluoride concentration in ground water samples around Ambikapur district in Sarguja revealed that fluoride content in beyond the permissible limit in a some residential areas. The extent of Fluoride present in different samples was obtained by spectrophotometer. the extent of fluoride was found in village Badadamali found to be from minimum 2.0 to 3.0 mg/l. village Khirbar found to be from minimum 2.1 to 3.0 mg/l. but in village Mudesha and Nandamali found to be from minimum 2.1 to 3.50 mg/l. it is further added that extent of fluoride content in water depends on the climatic conditions and increase in summerman_bsp@rediffmail.comResearch522015Climate,Dosage,Fluorosis,Permissible limit,ConsumptionManish Upadhyay,Suman Singh,Sudhir Pandey1 Associate Professor & Head, Dr.C.V.Raman University, Kargi Road, Kota, Bilaspur, Chhattisgarh 495001, India,Research Scholar, Dr.C.V.Raman University, Kargi Road, Kota, Bilaspur, Chhattisgarh 495001, India,Research Scholar, Dr.C.V.Raman University, Kargi Road, Kota, Bilaspur, Chhattisgarh 495001, India
