AbstractThis project deals with determining the fluoride on different ground water sample. In this broadside analysis of different ground water was tested for content of fluoride ions in bottled mineral water significantly differs from values given on declaration, and that content of fluoride ions varies over a period of time. The content of fluoride ions in water from ground water in Nagpur and Bhandara districts at the time of analysis was significantly increased and exceeded values given in Regulation for drinking water quality. The received results from the analysis of fluorides in teas show that fluorides exist in teas in different concentrations.
It may due to the presence of different types of fluoride bearing minerals with different solubility. Considering WHO safe limit 0.5 ppm or mg/L of fluoride in drinking water, nearly 82% of the tested waters are contained injurious concentration of fluoride for drinking water purposes limit 0.5 ppm or mg/L of fluoride in drinking water, nearly 82% of the tested waters are contained injurious concentration of fluoride for drinking water purposes. A safe limit of 0.5 ppm or mg/L of fluoride has been proposed for all types of crop plants. Also the Unsafe condition limit was 2.0 ppm or mg/ltr and Alert limit 1.0 ppm or mg/ltr .
