【Abstract】 Objective To know about disease distribution and extent ot injury of fluorine of poisoning in North of Xiao- qing River of Guangrao Courty and to put forward the practical and curing way.Methods Testing for including fluorine in drinking water uses the way of ion’s choosing electrode,but to the children of 8 to12 years old,uses the way of Dean to examine the fluorine teeth.Results We investigate the 117 villages lying in the North of Xiaoqing River,and there are 95 villages where the content of fluorine in drinking water is more than 1.00mg/L,and is 81.2% in all the investigated villages,in there villages, the most content of fluorine in drinking water is 6.45ml/L.The fluorine teeth are 72.19% and index is 1.84 in the examined 4 185 children of 8 to 12 years old.Conclusions The area of North of Xiaoqing River is medium epidemic area of local fluorine poisoning,and this causes by the deep water underground including more than fluorine.更多还原
