CONTAMINATION OF FLUORIDE IN GROUNDWATER AND ITS IMPACT ON HUMAN HEALTH IN PONDI-UPRODA BLOCK IN KORBA DISTRICT, CHHATTISGARHKRISHNA KUMAR KASHYAP, SANYOGITA SHAHI AND MANOJ KUMAR GHOSHAbstract Fluoride is a frequent chemical element present in groundwater. Fluoride can reduce dental caries when taken in modest amounts, increased fluoride concentrations could induce dental fluorosis or tooth decay, In April-May 2021, twenty-four samples were obtained at random from different villages in the Pondi-uproda block of the Korba district. The Ion-Selective Electrode (ISE) technique and TWAD water testing kit were used to assess the concentration of fluoride in groundwater. Fluoride levels ranged from 0.78 to 8.62 mg/l in the groundwater of the study area, according to the findings. The majority of people in these areas depend on groundwater for irrigation, drinking and domestic use. In this location, 66.6% of samples had fluoride that exceeded WHO permitted limits. Dental and skeletal fluorosis is caused by excessive fluoride levels in drinking water; as a result, a suitable defluoridation method for water treatment in this area should be used. |
