当前的世界环境

氟中毒是Rajasthan状态的普遍存产，因为许多地方的饮用水源是具有高浓度氟离子的研磨水。地下水的氟化物污染可能与区域地质方面相关。对于本研究，收集水样并分析了物理化学参数，即pH，EC，TDS，钙和镁硬度，总碱度，氯化物，硫酸盐，硝酸盐等，特别是斋浦尔饮用水的氟化物审议站（两个样品）;Jagatpura;杜尔加杜拉;sanganer;Gandhinagar;Baisgodam和Kanakpura火车站。每个站的饮用水源是地下水。 The analysed values were compared with the standard values of Bureau of Indian Standards (BIS) and World Health Organisation (WHO). The analysis shows that the fluoride concentration is much higher in the drinking water samples of Sanganer; Jagatpura; Jaipur main; Baisgodam and Kanakpura railway station where as it is within permissible limits for the drinking water of Durgapura and Gandhinagar railway station. According to BIS and WHO the fluoride concentration more than 1.5 mg/l is toxic and may cause Fluorosis. Too much of fluoride concentration leads to destruction of enamel and causes fluorosis leading to decalcification, dental disorder, mineralization of tendons, digestive and nervous system. Out of eight water samples six are of higher range and two comes in the permissible limits. Hence the study suggests the defluoridation of drinking water in the study area.
