目的了解河北省易县居民饮用水水氟含量,为防治地方性氟中毒提供科学依据.方法 2012年在河北省易县按《河北省居民生活饮用水水氟分布调查方案》开展调查.以行政村为单位,对集中供水的村,每村抽取1份末梢水.对分散式供水的村,如水源≤5个,全部采样;如水源＞5个,按东、西、南、北、中5个方位抽取5份居民饮用水水样.水氟检测采用《生活饮用水标准检验方法-无机非金属指标测定》(GB/T5750.2-2006).分析比较不同地貌,不同水源类型,不同井深饮用水水氟含量.结果在全县27个乡镇中共采集1 024份水样,水氟含量范围为0.06～1.08 mg/L,中位数为0.24 mg/L.山地、丘陵、平原分别采集水样490、505、29份,水氟中位数分别为0.26、0.22、0.21 mg/L.水氟含量山地高于丘陵和平原(x2=71.71、17.74,P均＜0.01),丘陵和平原水氟含量比较,差异无统计学意义(x2=2.48,P＞0.05).家用井水、自来水及山泉水分别采集水样742、228、54份,水氟中位数分别为0.22、0.24、0.33 mg/L.水氟含量山泉水高于自来水与家用井水(x2=53.16、50.85,P均＜0.01),自来水与家用井水差异无统计学意义(x2=1.69,P＞ 0.05).井深＜40 m及≥40m分别采集水样583、441份,水氟中位数分别为0.24、0.23 mg/L,不同井深饮用水水氟含量比较,井深＜40 m与井深≥40 m差异无统计学意义(Hc=0.17,P＞0.05).结论易县总体水氟含量不高,不会出现大面积地方性氟中毒的流行.

Objective To find out fluorine content in drinking water in Yi County,and to provide ascientific basis for prevention of endemic fluorosis and children's dental caries.Methods According to "FluorideDistribution Survey Program in Drinking Water of Hebei Province",an administrative village was taken as a unit,one drinking water sample was randomly collected from every village with centralized water supply.For villages withdecentralized water supply,five drinking water samples were randomly collected according to directions (east,west,south,north and centre) if there were more than five water sources in the village;samples from all the water sourceswere collected if there were less than five.Fluorine content was determined with drinking water standard testmethods (GB/T 5750.2-2006).Analysis and comparison of fluoride content in drinking water of different landscapes,water types and different well depth were carried out.Results The range of water fluoride content was 0.00-18.39 mg/L,and water fluorine median was 0.24 mg/L in 1 024 water samples in 27 towns in the county.Watersamples of 490,505 and 29 copies were collected in the hills,plains and mountains,and water fluorine medianwas 0.26,0.22 and 0.21 mg/L,respectively.Concerning water fluorine content in drinking water,mountains werehigher than hills and plains (x2 =71.71,17.74,all P ＜ 0.01).There was no significant difference between waterfluoride content in hills and plains (x2 =2.48,P ＞ 0.05).Water samples of 742,228 and 54 copies were collected,respectively,in household well water,tap water and mountain spring water,and water fluoride median was 0.22,0.24 and 0.33 mg/L,respectively.Concerning water fluoridation content in drinking water,spring water were higherthan tap water and household well water (x2 =53.16,50.85,all P ＜ 0.01).There was no significant differencebetween water fluoridation content in tap water and household well water (x2 =2.97,P ＞ 0.05).Water samples of583 and 441 copies were collected,respectively,in well depth ＜ 40 m and well depth ≥40 m,and water fluoride median was 0.24 and 0.23 mg/L,respectively,and there was no significant difference between water fluoridation content in the well depth ＜ 40 m and the well depth ≥40 m (Hc =0.17,P ＞ 0.05).Conclusions Fluoride content of drinking water in Yi County is not high,endemic fluorosis disease does not occur.
