Of the 200-odd villagers in the Indian town of Gaudiyan, around 135 have bone deformities. A private doctor who conducts social work in the area termed it as a case of skeletal fluorosis -- the result of excess fluoride content in drinking water.
In another part of India, also partly as a result of fluoride poisoning, children are losing their vision. They have been diagnosed with Lamellar Congenital cataract -- a condition in which the eye lenses are damaged.
According to The Times of India:
"...high fluoride content in water and Vitamin A deficiencies is ruining the lives of children of this taluk."
Other examples of such harm include the village of Sogival where the groundwater contains 4.84 ppm of fluoride and two-thirds of the people suffer from skeletal deformities. And in Bihar, the prevalence of physical deformity is yet another testament to excessive fluoride exposure.
