摘　　要：目的掌握河北省蔚县地方性氟中毒病区的改水现状及防治措施、控制效果。方法选取蔚县55个病区村,对8～12岁儿童氟斑牙患病率及改水设施运行情况进行调查。儿童氟斑牙检查采用Dean氏法,水氟含量检测采用氟离子选择电极法。结果正常使用的改水工程为29个,受益人口达56 751人,管网末梢水氟含量均值为0.80mg/L,范围为0.2～2.1mg/L。氟斑牙患病率为15.92%,氟斑牙指数为0.27。结论蔚县地氟病防治取得较好效果,但病区改水降氟的防病措施尚须加强。effects in Objective To master the drinking water defluoridation current state, preventive measures and control endemic fluorosis areas of Yu County Hebei province. Method Selected 55 endemic villages and in- vestigated the dental fluorosis prevalence rate of 8 to 12 old children and the operation status of drinking water defluoridation facilities. Children＇s dental fluorosis was examined by Dean＇s, fluoride content in drinking water was determined by fluorion selective electrodes. Results Total of 56 751 people were profited from 29 drinking water defuoridation projects. The average value of fuorides content in water of end pipe network was 0. 80mg/ L （0. 2 -2. 1mg/L） . The dental fluorosis prevalence rate was 15.92% and dental fluorosis index was 0. 27. Conclusions Endemic fluorosis prevention and control work received good effect in Yu County, but we still need to improve the drinking water defuoridation projects in endemic areas.
