University, Ajmer - 305 009, Rajasthan (India) Public Health Engineering Department (PHED) Laboratory, Bhilwara - 311 001 Rajasthan (India) Fluoride concentration of groundwater samples from 152 villages of Mandal tehsil of Bhilwara district of Rajasthan was determined. In the tehsil 90 villages (60%) were found to have fluoride concentration more than 1.5 mg/l which is maximum desirable limit of drinking water standards IS, 10500, 1999. 57% population of these villages have possibility of fluorosis. 11% population of tehsil living in 13 villages of intakes more than 5.0 mg/l fluoride with each liter of drinking water. In these villages there is a maximum possibility of dental and skeletal fluorosis. The maximum fluoride concentration in tehsil is recorded 8.3 mg/l in groundwater of Delas village. https://www.biotech-asia.org/vol2no2/fluoride-in-drinking-water-and-health-hazards-some-observations-of-fluoride-distribution-in-sahara-tehsil-of-bhilwara-district-rajasthan/ Fluoride; Fluorosis; Groundwater; Fluorosis affected zones; Bhilwara; Rajasthan
