7-Effects, Incidence and Investigation for Remedy of Fluoride in Drinking Water.

Abstract

Excessive concentration of fluoride in drinking water gives rise to dental decay and physiological deformations. From this point of view it is necessary to know the fluoride content of well water, which constitute the main source of drinking water in most parts of the country. It is observed that high incidence of fluoride in ground water occur practically in all types of rock formations. While small amounts of fluoride intake are essential for preventing dental carries, excessive amounts are unsafe as they cause the disease "Fluorosis". To determine the factor contributing to excessive fluoride concentrations, systematic experimental studies have to be made with different types of water and different types of rocks and soils containing fluoride bearing minerals. It is also imperative that preventive measures should be taken iminedictely to protect people from the intake of large amounts of fluoride through drinking water.
