摘要
目的 调查贝尔湖牧区居民摄氟量及主要氟源。方法 在新巴尔虎右旗选择两个典型病区,随机抽取10户居民,入户调查饮奶茶情况并采集饮水、砖茶和奶茶样品,用电极法测定氟化物含量。结果 两调查点饮水、砖茶和奶茶氟化物含量均很高;分别为4.12～4.37mg/L,780.3～800.0 mg/L和5.80～5.88 mg/L;两调查点成人经奶茶途径摄氟量分别为（8.70±3.91）mg/d和（9.50±3.22）mg/d,其中从饮水摄氟分别占75.34％和70.07％,从砖茶摄氟分别占24.66％和29.93％。结论 两调查点摄氟量远远超过国家标准,是以饮水型为主的混合型地方性氟中毒病区。
ve To investigate the intake of fluoride of residents in pastoral area of Beier Lake and its main source. Methods Two of the typical endemic fluorosis villages were selected as observation sites in Xinbaerhuyouqi County of Inner Mongolia Autonomous Region. The amount of milk-tea drank by residents was investigated, the drinking water samples, brick-tea samples and milk-tea samples were collected from 10 families randomly selected as observation families. The contents of fluoride of 3 kinds of samples were determined by iron selective electrode method. Results The contents of fluoride in drinking water samples, brick-tea samples and milk-tea samples reached higher levels, namely, 4.12-4.37 mg/L, 780.3-800.0 mg/L and 5.80-5.88 mg/L respectively in two investigation sites. The intake of fluoride from milk-tea of adults was (8.70 ±3.91) mg/d and (9.50±3.22) mg/d respectively, of which, 75.34% and 70.07% came from drinking water, 24.66% and 29.93% came from brick-tea in two observation sites. Conclusion The two observation sites with the higher levels of fluoride intake far exceeding the related Na-tional Standards were composite endemic fluorosis area with a fluoride exposure route mainly via drinking water.
