• 摘要：甘肃省阿克塞哈萨克族自治县的哈族、汉族居住地水源氟浓度为0.32mg/L,0.39mg/L,但哈族居民每日通过饮用砖茶熬制的奶茶,其日总摄氟量达到少儿6.046mg,成人8.948mg,当地汉族居民春、夏、秋季饮用普通花茶日总摄氟量为少儿0.962mg,成人4.879mg.大量的茶氟摄入导致哈族8-15岁少年儿童和成人氟斑牙患病率达到84.42%和93.33%,氟斑牙指数分别为3.05和4.25,属氟中毒重度流行人群。统计分析证实,哈族奶茶与汉族冬季饮用的砖茶与氟中毒反应呈明显的相关性(r=0.99,r=0.96).

• Abstract：The water fluorine concentrations were 0.32 mg/L and 0.39 mg/L in the Kazak and Han living areas at Akesa Kazak Minority Autonomous County, Gansu Province. Kazak inhabitants tota fluorine intake was 6.046 mg (children) or 8.948 mg (adults) per day by the way of drinking milk tea which made from brick tea water. Han inhabitants total fluorine intake was 0.962 mg (children) or 1.819 mg (aduts) every day by drinking ordinary flower tea at spring, summer and autumn, however, at winter, they drank brick tea. Their total fluorine intake was 2.492 mg (children) of (adults). Because of over intake of tea fluorine, the dental fluorosis morbidities of Kazak 8 to 15 years old children and adults were 84.42% and 93.33%, the indexes of dental fluorosis were 3.05 and 4.25. They were belong to sever fluorosis epidemic people. The investigation shows the dental fluorosis morbidities of Han children and adults were 25% and 38.39%, the indexes of dental fluorosis were 0.70 and 1.30. They were belong to middle fluorosis epidemic people. The statistic analysis shows the milek tea drunk by Kazak and the brick tea drunk by Han at winter had significant correlation with fluorosis ( r=0.99,r =0.96).
