摘要
目的了解甘肃省地方性氟中毒（简称地氟病）病区分布和改水降氟工程运行现状。方法2006年在甘肃省地氟病病区，对未改水村进行水源水氟检测；对已改水村进行降氟改水工程运行情况调查和水氟测定；在已查出的高氟村，对儿童进行氟斑牙和成人氟骨症患病情况调查。水氟测定采用氟离子选择电极法，儿童氟斑牙调查采用Dean法，氟骨症诊断执行《地方性氟骨症临床分度诊断》（GB16396—1996）标准。结果共调查了26个县、1997个村的不同类型饮用水源，水源水含氟量〉1．0mg／L的村占29．94％（598／1997）。共调查各类改水工程1215处，能正常供水的工程占工程总数的94．90％（1153／1215），间歇供水工程和已报废工程分别占工程总数的2．96％（36／1215）和2．14％（26／1215）。出厂水水氟均值≤1．0mg／L的工程占检测工程数的90．79％（1084／1194），末梢水水氟均值≤1．0mg／L的工程占检测工程数的91．75％（1068／1164）。共检查8～12岁儿童86390人，儿童氟斑牙检出率为22．47％（19414／86390）。共检查16岁以上成人142211人，临床Ⅱ度及以上氟骨症检出率为4．20％（5967／142211）。结论甘肃省少部分病区高氟水源依然存在。降氟改水工程报废和超标现象普遍；部分病区儿童氟斑牙和成人氟骨症尚在流行，防治任务依然艰巨，应加大改水力度，提高防病改水效益。
Objective To understand distribution of the endemic fluorosis areas and running status ＇of water-improving defluoridation projects in Gansu province. Methods In 2006, Gansu province endemic fluorosis areas, the content of fluoride in drinking water was measured in villages where water was not improved, running status of delluoridation projects was investigated and the content of fluoride in drinking water were determined in villages where water was improved. Dental fluorosis and skeletal fluorosis prevalence were examined in children in identified high-fluoride villages. The fluorine content in drinking water was determined by F-ion selective electrode, dental fluorosis of children was diagnosed using Dean method, and adults skeletal fluorosis was diagnosed according to ＂National Standard for Clinical Diagnosis of Endemic Skeletal Fluorosis＂ （GB 16396-1996）. Results Water samples were examined in 1997 villages of 26 countries, among which water fluoride content was higher than 1.0 mg/L in 598 villages, accounting for 29.94%（598/1997）. All 1215 water-improvlng and defluoridation projects had been investigated, among which 94.90% （1153/1215） of the projects were functioning well, and intermittent and abandoned projects accounted for 2.96% （36/1215） and 2.14% （26/1215）. Mean fluoride of treated water of 1084 water-improving and defluoridation projects had water fluoride content ≤ 1.0 mg/L, accounted for 90.79%（1084/1194） ; mean fluoride of water from 1068 water-improving and defluoridation projects had water fluoride content≤ 1.0 mg/L, accounting for 91.75% （1068/1164）. Total 86 390 children of 8 to 12 year-old were examined, the detectable rate of dental fluorosis was 22.47%（19 414/86 390） and 142 211 adults above 16 year-old were examined, the detectable rate of skeletal fluorosis was 4.20% （5967/142 211）, Conclusions Some villages yet have water fluoride content exceeding the standard. Some projects are abandoned and running badly, leading to fluoride content exceedin
