CORRELATION BETWEEN FLUORINE CONTAMINATED ANIMAL FODDER AND CATTLE MILK IN HIGH RISK FLUOROSIS DISTRICTS OF RAJASTHAN

The toxic effects of fluorine depend on the intake into the body, the solubility and bio-availability of it. When daily intake of fluorine is 0.5 to 1.7 mg/kg body wt. in the form of sodium fluoride produces dental lesions in growing animals without affecting general health, whereas the adult animals can tolerate double the dose of the above intake i.e. 1 to 3.5 mg/kg. body weight per day, Minor teeth lesion occurs at 5 ppm. In cattle lateral incisors show most pronoused changes. Mottling of tooth enamel, erosion of teeth are the earlier signs of dental fluorosis. Lucerne, Barley, Common Duckweed, Rapeseed, Red Clover, False oat grass, Rye grass, Corn, Millet, Sorghum, Wheat were analyzed in all seven districts, fluoride ranges from 2.197±0.107 to 5.624±0.219mg/kg in Lucerene and False oat grass respectively. Buffalos milk (6.034±1.837ppm) of Nagore district was highly contaminated.As concentration of fluoride increase in drinking water, there was increased concentration of fluoride in milk, blood and urine.
