摘要
目的了解山东省改水降氟工程运转使用的现状。方法对山东省所有改水降氟工程的运转使用情况按统一表格进行调查。结果自1980年至2001年,山东省共建设改水降氟工程5934处,以打低氟井为主;运转基本正常的工程4159处,占70.09%,不正常的工程26处,占0.44%,停用报废的工程1749处,占29.47%。5934处改水降氟工程共涵盖病村7880个。已改水病村中,有5689个村的工程运转基本正常,占73.54%;有2110个村的工程运转不正常和停用报废,占26.46%。停用报废的主要原因是管理不善、工程质量差、管道断裂和水氟超标。在改水工程运转基本正常的病村中,有4050个村的饮水氟≤1.00mg/L,占改水村的51%,占全部病村的35%;改水实际受益人口324万余人,占病区总人口的1/3。结论山东省改水降氟工程的水氟超标和停用报废现象严重,急需改进。
Objective To understand the present states of water-improving and defluoridation projects. Methods According to research standard of the present states for endemic fluorosis control. Results From 1980 to 2001, 5 934 water-improving and defluoridation projects were built in the whole province. The projects were mainly low fluoride wells. There were 4 159 projects that run normally, accounting for 70.09%; 26 projects run abnormally, accounting for 0.44%; and 1 749 projects were abandoned, accounting for 29.47%. There were 7 880 fluorosis villages that improved water quality and lowered fluoride, among which 2 110 villages had stopped using and abandoned the well, accounting for 26.46%. The main reasons for stopping and abandoning were administration failure, poor quality of projects, pipe line was destroyed and water fluoride concentration was over-standard. There were 5 689 villages′ projects run well, in which 4 050 villages had water fluoride concentration ≤1.00 mg/L, accounting for 51% of water-improving villages and 35% of total fluorosis villages. The population being benefited really was 324 ten thousands, accounting for 1/3 of the total population in the fluorosis region. Conclusions The phenomena that water fluoride concentration is over-standard, projects stopped using and abandoned are serious, and the preventive situation for endemic fluorosis control is still very severe in Shandong. So preventive measure for endemic fluorosis control must be strengthened.
