摘　　要：目的了解山西省忻州市改水降氟防治饮水型氟中毒效果及病情流行动态。方法按照《山西省地方性氟中毒监测方案》进行,水氟测定按照《生活饮用水标准检验方法》(GB/T5750-2006),尿氟采用氟离子选择电极法(WS/T89-1996);氟斑牙采用Dean法,临床氟骨症和X线氟骨症诊断采用《地方性氟骨症诊断标准》(WS/T192-2007)。结果累计改水降氟221处,覆盖病区村230个,覆盖率为80.7%,受益人口28.2万,占病区总人口的70.3%。检测居民饮用水462份,水氟均值为1.08㎎/L,范围值0.56～4.97㎎/L。检查8～12岁儿童氟斑牙7 352人,总检出率21.87%,氟斑牙指数为0.49。测定儿童尿样1 368份,总样本尿氟几何均值为1.67㎎/L,范围值0.52～15.36㎎/L。检查16岁以上人群31 728人,检出临床氟骨症患者4 935例,总检出率为15.55%,共X线拍片622人,检出X线氟骨症163人,检出率26.21%。结论忻州市改水降氟取得了可喜的成效,饮水型氟中毒病情得到控制;但在局部病情流行还较为严重,防治工作仍然任重道远。Objectives To understand the effect of water improvement project on defluoridation and epidemiological dynamic of drinking - water type fluorosis of Xinzhou city. Methods With Surveillance Program for Endemic Fluorosis of Shanxi Province and Standard Examination Methods for Drinking Water （ GB/T5750 - 2006 ） as guide we detected the fluoride content in drinking water. Fluoride content in urine was detected with fluoride ion selective electrode; Dental fluorosis determined by Dean method; Clinical and X - ray skeletal fluorosis were tested by diagnostic standard for endemic skeletal fluorosis （ WS/T192 - 2007 ）. Results We carried out water improvement and defluoridation project on 221 experimental units covering 230 villages with the coverage rate of 80.7% benefiting 282 thousand people and accounted for 70.3% of the whole population in endemic area, 462 drinking water was detected, the average water fuoride value wasl. 08mg/L ranged from 0.56 to 4.97 mg/L, 1 7352 children were surveyed aged from 8 to 12 positive rate was 21.87% , dental fluorosis index was 0.49; 1368 urine samples of children were determined, geometric average of urine fluorine in total sample was1.67 rrlg/L from 0. 52 to 15.36 mg/L; 4935 cases were diagnosed with clinical skeletal fluorosis in 31 ,728 people aged over 16 years old, the overall detection rate was 15.55% ; 622 people were examined with X -ray and 163cases of skeletal fluorosis was detected, detection rate was 26.21%. Conclusion Water improvement and defluoridation project achieved results in Xinzhou , but fluorosis still spread in certain area, prevention and control work still has a long way to go.
