摘要 目的评价石家庄市高氟地区经改水降氟后取得的成效。方法选取4个高氟改水村和1个水氟正常村,进行饮用水氟含量监测,并对8~12岁学生进行氟牙症检查和尿氟数据检测。结果各村水氟浓度均<1.0mg/L,尿氟中位数为0.82mg/L(0.35~1.88mg/L),氟牙症指数为0.15。尿氟与可疑及患病情况所占比例间有线性相关关系(F=41.307,P=0.000),R2=0.821。结论经改水降氟后,饮用水均达到了国家卫生标准要求,儿童尿氟和氟牙症指数在正常范围。但个别高氟改水村的儿童尿氟中位数偏高,需加大水氟浓度的波动检测和其他氟来源检测。 Objective To evaluate the effects in deflurioidation area in Shijiazhuang city.Methods Portable water fluorine content was measured among 4delfluoredation villages and 1village with normal water fluorine.The dental fluorosis and urine-fluoride of students aged 8-12were tested.Results The results showed that the fluorine content in drinking water of all investigated villages were lower than 1mg/L.The median of Urine-fluoride was 0.82mg/L(0.35-1.88mg/L).Index of dental fluorosis was 0.15.There was a linear correlation between urine-fluoride and the prevalence of suspected fluorosis and dental fluorosis(F=41.307,P=0.000),R2=0.821.Conclusions After water-improvement,water-fluorine concentration was lower than the hygiene standard of our country.Indexes of Urine-fluoride and dental fluorosis were in normal range.In very few villages,the madian of urine-fluoride stayed high.We should enhance our monitoring over fluoride in water and other sources of fluorine.
