【摘要】 为及时、准确地了解湖北省饮水型氛中毒病区改水降氟效果，于1993～1995年连续三年对丹江口、枣阳、通城和罗田等四县市已改水的四个氟病区监测点进行了改水工程的落实和降氟效果的监测．结果表明：四县市管理措施落实较好的改水工程占整个改水工程的80％以上，8～12岁儿童氟斑牙、尿氟和水氟逐年下降或维持在正常水平，防治效果显著（P＜0．05）．因此饮用低氟水，改水降氟是预防饮水型氟中毒的根本措施，而改水后保证水氟含量的稳定，加强供水管理和设备维修等则是保证防治措施有效的关键。更多还原

【Abstract】 To know the efficiency of defluoridation of drinking water in Hubei province, four surveing stations were built to observe the efficiency of the defluoridation construction. Theresults showed th at 80% constructions were efficient, for the incidence of dental fluorosis, urinary fluorine and water fluorisis levels of school-age children was reduced every year. So we can make a conclusion that drinking low fluorisis water and preserving defluoridation are the efficient measures for endmic fluorosis control.更多还原
