目的了解西藏谢通门、八宿2县饮水型氟中毒流行现状,为制定防治策略提供科学依据。方法2007年7月,采集监测点所有的饮用水进行氟含量检测,随机抽取8～12岁儿童800名检查氟斑牙(用Dean氏法)患病情况。结果检测水样48份,结果显示全部符合国家氟含量标准;8个村8～12岁的800名儿童氟斑牙检出率94.5%。结论监测点饮用水水氟含量未超标,但儿童氟斑牙检出率较高。
Objective To understand the prevalence of drinking water fluorosis in Xietongmen and Bazu 2 counties of Tibet and provide a scientific basis for formulating prevention and control strategies. Methods In July 2007, all the drinking water in the monitoring sites was collected to test the fluoride content. A total of 800 children from 8 to 12 years old were examined for the prevalence of dental fluorosis (Dean’s method). Results 48 samples of water samples were tested. The results showed that all the samples were in compliance with the national standard of fluorine content. The detection rate of dental fluorosis in 800 children from 8 to 12 years old in 8 villages was 94.5%. Conclusion The fluoride content in drinking water at the monitoring point is not exceeded, but the detection rate of dental fluorosis in children is higher.
