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 the investigation of the drinking water, air and food in two villages in the coal-burning fluorosis poisoning ward in Pingxiang City, it found that the incidence of dental fluorosis was 51.8% in Changping Village. The total amount of fluoride taken per day for adults was 3.167mg, while the incidence of dental fluorosis 57.4% temperature Pan Village, the total fluoride intake of 3.014mg. The fluorine content of air in the two villages is very similar, Changping Village, food pollution is heavier; and air SO2 content, Wen Pan Village Changping Village higher. Animal experiments show that living in the air fluoride content is similar, and SO2 high groups, the incidence of dental fluorosis is high and more serious. Population survey and animal experiments can be seen SO2 on the incidence of dental fluorosis and lesions have a role in promoting.
