摘要

To control the epidemic fluorosis in a visible impact within a reasonable time, either water can be brought from distant sources for domestic consumption or by the defluoridation of the contaminated water. In India defluoradition is done by Nalgonda process and by activated Alumina process. But in both these processes the treated water contains the residual aluminium in the range of 2.1 to 6.8 mg/lit which has again created another health risk. Aluminium even at a lower concentration of 0.08 ppm in drinking water causes Alzheimer's disease. Further the cost of defluoradition is so high that rural people cannot afford. Hence a low cost defluoridation technology should be developed which could avoid the major shortcoming of the above technology. However, the following other steps may be taken to control fluorosis : a) By avoiding food items rich in fluoride like Maize, red grass, red chilli. b) By avoiding tobbaco, bettle, Panmasala, Gudakhu, Supari. c) By avoiding fluoridated toothpaste and mouth rinse. d) By avoiding fluoride rich cosmetic products. e) Calcium enriched diet should' be taken regularly so that it will form calcium fluoride which is an insoluble salt and absorption will be less. f) Vitamin C and D should be taken. During primary survey in Balasingh and Singipur (Khurda district) the situation is so bad that the villagers did not allow us to take photographs and even the angry villagers initially refused to talk. "People from outside don't want to give their daughters in marriage nor do they accept our daughter as bride for the last fifteen years", said an angry Debraj Parida. Forty nine year old Hadu Pradhan who was rarely able to stand on his badly twisted limbs said that he is forced to drink the poison as there was no alternative. Chhakradhar Baliarsingh (46), with his body badly disfigured tersely said that he did not need any one's sympathy. So due to fluorosis, not only teeth and bone are affected but also new psycho-sociological problems are created.
