Mapping of fluorosis affected villages

Excess fluoride in drinking water sources beyond a tolerance limit is responsible for the disease ‘fluorosis’, a serious public health problem in several parts of the world. Identification and mapping of fluorosis affected villages is the first step in the direction of mitigating and controlling the problem. A systematic study has been carried out in order to map the fluorotic villages of Dindigul Anna district of Tamil Nadu, South India and a suitable methodology has been developed for the purpose. This methodology for mapping the fluorosis affected villages is presented in this paper.
