TY - JOUR T1 -关于Shivpuri区Karera和Narwar街区氟化物毒性的最新研究(M.P.)N2——如果饮用水中的氟(F -)浓度超过并超过允许的限值(1.5mg/l)，那么它就会导致严重的人类健康危害，如氟骨症和牙氟中毒，影响到世界上数百万人。印度许多邦的水资源中氟化物含量很高;中央邦就是其中之一。为了调查Shivpuri区饮用水中氟化物的浓度，对Karera和Narwar区7个村庄的饮用水样本进行了分析。结果显示，氟化物浓度为1.21 ~ 4.89 ppm，超过了允许限值(1.5mg/l)。结果表明，75% ~ 80%的样品的浓度高于允许限值。受氟化物影响最严重的村庄是Hatheda、Phulpur、Bichi、Baroda、Doni和Dahertasani。这些村庄的大多数人患有氟牙症和氟骨症。研究区地下水中氟化物的来源主要是地质赋存。研究区岩性单元为太古代花岗岩、成因杂岩、页岩和石灰岩。 It is unfortunate that the people living in these villages are consuming the water easily accessible to them without knowing the ill effects of such consumption. Government is also playing an active role by installing defluoridation plants based on Nalgonda technique and carrying defluoridated water through pipelines from other unaffected villages. But all these efforts are seem to be unsatisfactory if the people of villages are not involved seriously .An urgent need is to educate the people on the causes of fluorosis and encouraging rain water harvesting.
