College, Bhopal - 462038 (INDIA) <p style="text-align: justify;">Groundwater contains fluoride ion dissolved from geological formations. Excessive concentration of fluoride in borewells (groundwater) and drinking water causes dental fluorosis, and also referred to mottling of teeth. Low concentration and absence of fluoride in groundwater results in a high incidence of dental caries in children&rsquo;s teeth. Hence, it becomes very important to analyse the fluoride in groundwater of Bhopal city. In the present study sodium arsenate, zirconyl acid solution and Alizarin red-S is used in electrode screening method. The fluoride in this study has assessed in the range of 0.008 to 0.660 ppm at different sampling stations, during the year 2004-05.<br /> &nbsp;</p> https://journalofchemistry.org/paper/815/ Fluorosis Dental caries Electrode Screening manure.
