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。
Objective To understand the distribution of fluoride in drinking water and the use of water and fluoride reduction project in Guzhen County, so as to provide basis for further improvement of water and fluoride removal. Methods Screening was carried out in villages as a unit. Five samples of hand-wound well water samples were collected for fluoride determination. Results A total of 1 155 natural villages were surveyed, of which 486 were natural water fluorides, accounting for 42.08% of the total. Of the 6 villages and townships, more than half of the natural water fluorides exceeded the standard. The water fluorine exceeding standard was 3.96% Exceeding the standard phenomenon in the county widespread; low proportion of ultra-high water fluoride; water fluoride project results are not satisfactory.
