摘要
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 。
Objective To find out the disease state and epidemic features of brick tea type fluorosis among Tibetan and Mongolia children for drawing up hygienic standards and preventive strategy.Methods One of typical dieases areas was selected in the north of China,and also one in the south of China,then the cross sectional study was made from May to July,1999.The dental fluorosis was diagnosed by means of Dean's method.The fluoride content of drinking water,urine and brick tea water or milk tea water were determined using an ion specific electrode potentiometer.Results In Aba and Chembaerhuqi counties,fluoride contents of drinking water were lower than 1.00 mg/L.The disease state at livestock area of Aba county was most serious,at where the prevalence rate of dental fluorosis was 62.32%,secondly at Gedeng Temple of Aba county prevalence rate of dental fluorosis was 57.83%.In Chenbarerhuqi county,the disease states were slighter,and even negative level.The fluoride contents of milk tea at livestock area of Chengbaerhuqi county were 2.91mg/L,and higher than the livestock area(1.98mg/L) of Aba county.In Aba and Chengbaerhuqi county town,the fluoride contents of brick tea water or milk tea were almost equal,approximatoly 2.9 mg/L.Conclusions The disease states of brick tea type fluorosis among Tibetan children of Aba county were more serious than those of Mongolia children of Chenbaerhuqi county,but in Aba county contents of urine fluoride were lower.
