目的 调查藏族、蒙古族儿童饮茶型氟中毒的病情严重程度、流行特征 ,为研制砖茶氟含量标准提供参考。方法 在四川阿坝县、内蒙古陈巴尔虎旗 (简称陈旗 )各选当地典型氟病区 ,进行现况调查。调查对象为 8~ 12岁儿童 ,氟斑牙按 Dean氏法诊断。饮水氟、尿氟、茶水氟、奶茶氟均采用氟离子选择电极法测定。结果 阿坝县和陈旗的水氟含量均低于 1.0 mg/ L。阿坝的藏族牧区病情最重 ,氟斑牙检出率为 6 2 .32 % ,其余是阿坝的格登寺 ,检出率为 5 7.83%。陈旗调查点 ,病情较轻。陈旗牧区的奶茶氟平均含量 (2 .91m g/ L ) ,高于阿坝牧区茶水氟平均含量 (1.98m g/ L ) ,两地城镇茶水氟含量相近 ,均为 2 .90 mg/ L左右。结论 阿坝县藏族儿童饮茶型氟中毒病情比陈旗蒙古族儿童严重 ,然而尿氟含量却相对较低
Objective To investigate the severity and prevalence of drinking-type fluorosis in Tibetan and Mongolian children, and to provide a reference for the development of fluorine content in brick tea. Methods A survey was carried out on typical endemic areas in Aba County, Inner Mongolia, and Chenbaerhu Banner in Inner Mongolia (Chen Banner). Subjects were children aged 8 to 12 years and dental fluorosis was diagnosed by Dean’s method. Drinking water fluorine, urine fluoride, tea fluoride, milk tea fluorine fluoride ion selective electrode method. Results The water fluoride content of Aba County and Chenqi was less than 1.0 mg / L. Aba Tibetan pastoral areas the most serious, dental fluorosis detection rate was 62.32%, the rest is Gordon Temple in Aba, the detection rate was 5 7.83%. Chen flag investigation point, the disease is mild. The average milk tea content (2.91 m g / L) in Chenqi pasturing area was higher than the average fluorine content in tea area (1.98 m g / L) in the pastoral area of Aba County. The fluoride content in tea in the two cities was similar, both of which were about 2.90 mg / L. Conclusion The prevalence of drinking fluorosis in Tibetan children in Aba county is worse than that in Chenqi Mongolian children, but the urinary fluoride content is relatively low
