According to BIS and WHO the fluoride concentration more than 1.5 mg/l is toxic and may cause Fluorosis. Too much of fluoride concentration leads to destruction of enamel and causes fluorosis leading to decalcification, dental disorder, mineralization of tendons, digestive and nervous system. Out of eight water samples six are of higher range and two comes in the permissible limits. Hence the study suggests the defluoridation of drinking water in the study area. ER -
