| Popis: | If the fluoride (F -) concentration in the drinking water is over and above the permissible limits (1.5mg/l) then it leads to severe human health hazards like skeletal and dental fluorosis, affecting millions of people in the world. Many states of India have high concentration of fluoride in their water resources; Madhya Pradesh is one of them. In order to investigate the concentration of fluoride in potable water of Shivpuri district (M.P.), drinking water samples from 7 villages of Karera and Narwar block, (Shivpuri district, M.P.), were analyzed. The results revealed that the fluoride concentration was found to be 1.21 to 4.89 ppm, which is more than the permissible limit (1.5mg/l).It was found that 75% to 80%of the samples studied have more concentration than the permissible limit. The worst fluoride affected villages were Hatheda, Phulpur, Bichi, Baroda, Doni and Dahertasani. Most of the people in these villages suffer from dental and skeletal fluorosis.The source of fluoride in ground water of the study area is mainly from geological occurrence. The litho logical units of the study area consist of Achaean granite, genesis complex rocks, shale and Limestone. 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. |
