摘要
目的了解河南省安阳市降氟改水工程运行状况及水氟情况。方法在安阳市的安阳县、滑县、内黄县、汤阴县4个地方性氟中毒(简称地氟病)病区,按照5个不同方位,采取整群抽样的方法抽取1/3的乡(镇),对被抽取乡(镇)的全部改水工程运行状况进行调查并检测运转正常的改水工程的水氟。结果在安阳市4个病区县共调查472处降氟改水工程,其中正常使用工程占90147%(427/472),报废工程占9.53%(45/472);检测427处改水工程的水氟,其中水氟合格工程占68.62%(293/427),水氟超标工程占31.38%(134/427);滑县报废工程数量较多,占41.00%(41/100),内黄县水氟超标工程数量较多,占70.39%(107/152)。结论安阳市滑县和内黄县降氟改水工程报废和水氟超标问题较严重.应认真分析原因,制订措施,指导全市降氟改水工作健康持续发展。
Objective To investigate the running condition of defluoridation projects and fluoride concentration in drinking-water in Anyang City of Henan Province. Methods Cluster sampling of Anyang, Hua, Neihuang, Tangyin Counties emdimic fluorosis poining of Anyang City was conducted places of different orientation, about 1/3 towns in the selected examination towns had their defluoridation project investigated. Results Among 472 projects investigated, 427 were running normally, accounting for 90.47% (427/472), only 9.53% (45/472) of the projects were out of service. 68.62% (293/427) of the projects had normal fluoride concentration in drinking water, 31.38%(134/427) of the projects failed to do so. In Hua County, 41.00%(41/100) of the projects were out of service. In Neihuang County, 70.39% (107/152) of the projects had abnormally high fluoride concentration in drinking water. Conclusions Defluoriding projects are out of service and fluoride concentration in drinking water exceeds the standard in Hua, Neihuang Counties of Anyang City. We must analyse the cause of it seriously, work out measures, promote a healthy and sustainable development of defluoridation projects
