摘要
目的 为了解湖南省饮水型氟中毒病区改水工程运行情况及其降氟效果。方法 运用流行病学方法对饮水型氟中毒病区进行了抽样调查。结果 8～ 12岁氟斑牙患病率较改水前均有显著下降 ,除资兴汤市、临湘金盆、邵阳新利为 4 1.6 7% ,37.93% ,4 0 .4 8%外 ,其余各点均下降到 30 %以下 ,饮水氟含量除邵阳新利和平江县木金乡亲和村部分井水超标外 ,其余各点均 <1.0 m g/ L,8～ 12岁学生尿氟也有明显下降。结论 通过改换低氟水源 11～ 15年 ,饮水型氟中毒病区改水降氟防病效果显著。
Objective To understand the using state of water improvement to reduce fluoride project and the effect of reducing fluoride in drinking water type fluorosis areas in Hunan.Methods Sampling investigation was carried out by Epidemicologic methods.Results Dental fluorosis prevallence rates of 8~12 years old children were reduced obviously than before (the project of water improvement was carried out),and were lower than 30%,except Tangshi of Zixing country,Jinpen of Linxiang country and XinLi of Shaoyang country.Except 2 of 25 villages fluoride concentration of water was lower than 1 mg/kg, and urine fluoride of 8~12 year old students was obviously reduced.Conclusions Effect of water improvement to reduce fluoride and prevent disease was obvious,after the project has been on 11~15 years.
