固镇县居民饮水含氟量筛查结果分析

目的了解固镇县居民饮水含氟分布情况和改水降氟工程使用情况,为进一步做好改水降氟工作提供依据。方法以自然村为单位开展筛查,采集5份手压井水样做氟化物含量测定。结果共调查自然村1 155个,其中水氟超标自然村486个,占42.08%;有6个乡镇一半以上的自然村水氟超标;改水降氟工程水氟超标率为3.96%;结论饮水含氟量超标现象在全县境内广泛流行;超高水氟所占比例低;改水降氟工程使用效果不理想。

Analysis of Fluoride Level in Drinking Water in Guzhen County

Objective To understand the distribution of fluoride and the application of the engineering of reducing the fluoride in drinking water of Guzhen country.Methods To detect fluoride level in the 5 handpump water samples of each natural village by screening.Results A total of 1155 villages were surveyed,among which the fluoride over standard were 486,accounting for 42.08%.There were 6 towns in the whole county with the fluoride concentration in drinking water exceeding the standard,and the proportion was over 50% of the total.!While the proportion of fluoride exceeding the standards was only 3.69% in the engineering of reducing the fluoride level.Conclusions It is widely seen that the fluoride level in drinking water exceeds the standard in the whole county.The fluoride reducing engineering hadn't achieved the expected results.
