摘要目的　研究人群尿氟、发氟在 地方性氟中毒病区的判定与防治效果评价中的作用。方法　选择饮水含氟量相近的村为调查点，分为6个水氟剂量组，对长期居住在当地的人群用氟离子选择电极法作尿氟和发氟含量检测。结果　饮水含氟量与尿氟含量有高度的相关性，与发氟无相关性；尿氟与发氟含量无相关性；尿氟、发氟含量在非病区与病区和轻病区与中等病区之间均有极显著差异。结论　人群尿氟、发氟均可作为确定地氟病病区的参考依 据，尤其是在环境氟较高，但尚未产生明显的健康效应，暂时不能根据病情资料确定病区或氟污染危害等情况下，用群体尿氟水平作为确定地氟病病区或判定氟污染危害，评价其防治效果是一项 重要依据；由于发氟检测方法较复杂等原因，应用范围受到限制。

abstractsObjective　To study the function of urine flu orine (UF) and hair fluorine (HF) in controlling of fluorosis.Methods　Villages that have approximately the same level of fluorine(F) in drinking water were chosen.UF and HF were measured in the villages.Results　The level of F in drinking water was highlyrel ated with UF but not with HF.UF and HF was not related.Statistical significantd ifferences of UF and HF were found between endemic and non-endemic,light and mid-severe areas.Conclusions　Both UF and HF can be used to determine end emic areas,especially in high Fenvironment.
