煤烟对食物、饮水氟污染的研究

Study on the Fluorine Contamination of Food and Drinking Water Due to Coal Smoke

测定了云南滇东“燃煤污染型”氟病区新、陈玉米（皮、饭）、饮用水（自然井水、泉水、室内缸水、开水）的含氟量．并对玉米、豆类、辣椒进行水洗脱氟试验．结果证明由于用煤方式不当，造成室内食物、饮水的污染，发生氟中毒。

The author determined the fluorine content of fresh and dry corn, as well as drinking water (from well, spring. indoor water tank and boiled water) from the areas of endemic fluorosis located in the northeast of Yunnan province. In these areas, fluorine contamination was due to coal smoke. Meanwhile, corn, bean and hot pepper were eluted to remove fluorine.The results proved that fluorine contamination of indoor food and drinking water due to the improper way of using coal resulted in fluorosis.
