摘要
通过萍乡市燃煤污染型氟中毒病区两个村的饮水、空气和食物的调查，发现氟斑牙发病率为５１．８％的长平村，成人每人每日的总摄氟量为３．１６７ｍｇ，而氟斑牙发病率为５７．４％的温磐村，总摄氟量为３．０１４ｍｇ。两个村的空气含氟量十分近似，长平村的食品污染较重；而空气ＳＯ２含量，温磐村较长平村要高。动物实验显示，生活于空气含氟量近似，而ＳＯ２高的群体，氟斑牙的发病高且病情更严重。人群调查和动物实验均可看出ＳＯ２对氟斑牙发病和病变程度有促进作用。
Through surveys on drinking water, air and food in two villages in burning coal pollution-type fluorosis areas of Pingxiang Region, it is found that adult′s fluoride intake is 3.167mg/day in Changping village in which the in cidence of dental fluorosis is 51-8%; but that is 3.014mg/day in Wenpan Village, in which the incidence is 57.4%. In the two villages, the contents of fluoride in air are similar; there are more serious fluoride pollution in food of Changping Village, but higher SO 2 Content in air of wenpan village The result of animal experiments demonstrated that the pobulation, which live in Surroundings with similat content of fluoride but higher content of SO 2 in air, have a higher incidence of dental fluorosis and more serious lesion. It is shown that SO 2 has an effect of promotion on the occurrence and seriousness of dental fluorosis.
