摘　　要：[目的]了解济宁市农村降氟改水后生活饮用水中氟含量情况,为预防地方性氟中毒提供依据。[方法]2008年,在济宁市所辖8个县(市、区)农村抽取部分降氟改水后生活饮用水进行水氟含量调查。[结果]138个检测点均未设消毒设施,未采取除氟措施;水源为深井的占87.68%。枯水期、丰水期各检测276份,水氟含量合格率分别为82.97%、87.68%(P>0.05);52个高氟为主的监测点,枯水期、丰水期各104份水样氟含量合格率分别为78.85%、82.69%(P>0.05)。8个县(市、区)中,任城区、邹城市、兖州市枯水期和丰水期水样氟含量均合格;其他5个县(市)均有氟含量超标的水样,枯水期、丰水期超标率的差异均有统计学意义(P<0.01),梁山县和金乡县合格率较低。[结论]济宁市农村降氟改水后生活饮用水氟含量超标率较高。[Objective]To understand the content of fluorine in drinking water in rural areas of Ji＇ning after the implementation of water-improving and defluoridation project,provide basis for the prevention and control of endemic fluorosis.[Methods]Drinking water samples collected from the rural areas of 8 counties,districts of Ji＇ning city were tested for the content of fluorine after the implementation of water-improving and defluoridation projects in 2008.[Results]There were not any disinfection facilities in 138 monitoring spots,no defluoridation operation and deep-well water source accounted for 87.68%.276 water samples were tested in dry and wet season respectively,the qualified rate of fluoride in drinking water was 82.97% in dry season and 87.68% in wet season（P〉0.05）.Of the 104 water samples collected during dry and wet season of the 52 monitoring spots with high content of fluoride,the qualified rate was 72.85% in dry season and 82.69% in wet season（P〉0.05）.The water samples collected from Rencheng district,Zoucheng and Yanzhou city were up to standard.Some of the water samples collected from other 5 counties and cities exceeded the standard,there was a difference of the exceeded rate in dry and wet season（P〈0.01）.The qualified rate was lower in Liangshan and Jinxiang county.[Conclusion]The excess standard rate of the content of fluoride in drinking water after the implementation of water-improving and defluoridation projects was higher in rural areas of Ji＇ning city.
