Abstract:
Water provides a unique medium to many physical, chemical and Biochemical Processes. Any minute change in water quality parameter may adversely and favorably affect the ecosystem as well as biological and industrial process. Fluoride in low concentration of 0.5 to 1.5ppm is beneficial for human health but its excess amount can cause serious health hazards and can interfere with various industrial synthetic pathway. Different forms of fluoride exposure are of importance and have shown to affect the body's fluoride content and thus increasing the risks of fluoride-prone diseases. Fluoride has beneficial effects on teeth at low concentrations of 1 mg/L by preventing and reducing the risk of tooth decay. Concentrations lower than 0.5 mg/L of fluoride however have shown to intensify the risk of tooth decay. Fluoride can also be quite detrimental at higher concentrations exceeding 1.5 – 2 mg/L of water. High concentrations of fluoride pose a risk of dental fluorosis as well as skeletal fluorosis and osteoporosis. In present study drinking water samples from various recourses of Punjab and northern Rajasthan have been analyzed in triplicate with respect to pH, alkalinity, Total hardness,turbidity, content. The area under study is extension of peninsular block and mainly composed of quartzite, sandstone, micaschilt, phyltis etc. which are responsible for high F content in area. In this study F content water sample is correlated with the depth, alkalinity, pH, total hardness and carbonate content. The study will be helpful to many water quality analysts, biologists, ecologists, environmentalists and industrialists.
