临猗县饮用水氟含量调查与评价

Analysis and Assessment on the Fluoride Content of Drinking Water in Linyi County of Shanxi Province

为了评价山西省高氟区临猗县防氟供水工程实施效果,对临猗县16个乡镇85个自然村的135个测试点进行了调查采样,测定了饮用水中的氟含量。同时调查和收集了1984年、2002年和2008年临猗县饮用水氟含量的监测数据。结果表明,防氟供水工程实施后,高氟区乡镇的居民饮用水氟含量已经明显降低,但防氟供水工程没有辐射到的乡镇饮用水氟质量浓度仍在1mg/L～3mg/L之间。

To assess the operation effect of the defluoride and water supply project in Linyi County,the high fluoride area in Shanxi Province,this paper investigates and samples 135 points in 85 villages of 16 towns in Linyi County. The fluoride content in drinking water in 1984,2002 and 2008 are collected. The results show that after the project is finished,the fluoride content in drinking water is reduced obviously in high fluoride areas,but the areas where the project doesn t carry out is still among 1-3 mg·L^-1.
