Fluoride is an electronegative element present naturally in the earth’s crust as well as rocks and minerals. Exposure to fluoride contaminated drinking water beyond the recommended level for longer duration causes fluorosis - a irreversible deadly disease which may lead to serious public health hazards. Present study has been undertaken for the determination of fluoride in drinking water of 19 blocks of Birbhum district, West Bengal. Fluoride concentration in ground water of some villages has been found much above the maximum permissible limit like Nasipur reveal maximum fluoride concentration of 46 mg/L (almost 40 times higher than the permissible limit by WHO).In these areas, villagers have been found to be suffering from dental, skeletal and gastro-intestinal fluorosis. From our nutritional surveys of people of fluoride affected areas and statistical analysis (with the help of S+ software) we have found that poor nutritional level enhances the fluorosis problem. We have isolated three bacterial strains from fluoride contaminated wells. They have the ability to survive in a medium containing high concentration of fluoride ions. A simplified mathematical model of fluoride and bacterial dynamics has been proposed. Analytical solutions show that the bacterial consumption and growth rates are the most important parameters and asymptotic stability of the system. We have also found that the use of some fluoride accumulating plant species indicated good results for minimizing the fluoride content from soil and water. This present work focuses on the actual need of nutrients to resist fluorosis in the contaminated area and biotechnological potentiality to remove fluoride from contaminated water and soil with the help of bacteria and plant species.
