目的了解山西省改水降氟工程运行及使用现状,为加快地方性氟中毒防治工作提供科学依据.方法 2005-2009年,根据国家<地方病防治项目技术方案>,在山西省实施改水降氟措施的县(市、区),对降氟改水工程运行现状进行调查,并采用氟离子选择电极法检测水氟.结果本次共调查了51个县(市、区)1658处降氟改水工程,改水工程类型中打井占93.12%(1544/1658),以打井为主.正常运行的改水工程为1405个(占84.74%),间歇运转工程为190个(占11.46%);报废工程为63个(占3.80%),其中大同盆地改水工程报废率达到36.36%(12/33).在1595处可运行工程中水氟＞1.0 mg/L为874个(占54.80%),不同盆地的降氟改水工程超标情况不同(H=33.22,P＜0.01),其中大同盆地超标率达88.37%(38/43),大同盆地改水任务艰巨..结论全省改水降氟工程运行情况较好,但改水工程水氟合格率较低,各地区改水工程超标情况差异较大,防治形势依然严峻,今后应进一步加大改水工作力度.

Objective To learn the present status of defluoridation water improvement project in Shanxi province in order to provide scientific basis for speeding up the prevention and control of endemic fluorosis.Methods According to "The National Technical Scheme for Endemic Disease Control" from 2005 to 2009, the investigation points were selected in the counties that implemented the measures of water improvement and defluoridation,the status of drinking water defluoridation Project was investigated, and the water fluoride levels were determined by fluoride selective ion electrode. Results The primary status was surveyed in 1658 water improvement and defluoridation projects in 51 counties. The resource of drinking water for water improvement and defluoridation projects was mostly ground water[accounting for 93.12% (1544/1658)]. Among 1658 water improvement and defluoridation projects 1405 projects worked well(accounting for 84.74%) and 190 projects intermittently worked (accounting for 11.46%). Sixty three projects abandoned (accounting for 3.80%), in Datong basin the abandoned projects accounted for 36.36% (12/33). Water fluoride content of 1595 water improvement and defluoridation projects had been determined, among them water fluoride content of 874 projects were above 1.0 mg/L (accounting for 54.80%). The situations of exceeded national standard in the five basins was different(H = 33.22,P ＜ 0.01). The rate of over national standard of fluoride levels in drinking water was 88.37%(38/43) in Datong basin. Therefore, in Datong basin water improvement should be strengthened. Conclusions In Shanxi province the water improvement and defluoridation projects are basically running normally. However, the qualified rate is lower for the water improvement and defluoridation projects. The water improvement status varies dramatically among areas.The situation is still grim in Shanxi province. Water improvement and defluoridation needs to be strengthened to improve the effect of prevention and control of the disease.
