Abstract
Fluoride is an acute toxin and is deemed to be slightly more dangerous than
even lead. 48 water samples collected from hand pumps and bore wells belonging to
24 gram panchayats (villages) of Kanduku revenue sub division of Prakasam district in
Andhra Pradesh, were chemically analyzed for fluoride ion concentrations. High and
low fluoride containing regions were identified on the basis of fluoride levels in the
water samples and also on the prevalence rate of dental and skeletal fluorosis of the
study area. Further, water samples containing high fluoride levels were tried for
defluoridation by employing Active Carbons of abundantly available low-cost plant
byproducts. These materials under optimum conditions of adsorbent dosage, time of
equilibration and pH, were found to be successfully decreasing the fluoride ion
concentration below permissible limits without disturbing drinking water quality
standards.
