摘　　要：应用等离子体发射光谱仪(ICP-OES)法测定了内蒙古饮茶型氟中毒病区锡林浩特市有长期饮砖茶习惯的蒙古族牧民以及对照组(不饮砖茶的汉族居民)的发和尿中Ca,Mg,K,Al,P,Cu,Zn,Fe等八种生命元素的含量。标准物质测定结果满意,方法精密度介于2.32%到8.03%之间。通过人发和人尿样品的测定,发现长期饮砖茶人群的发铝、发镁、发钾明显高于对照组(P<0.05),尿铝、尿钙也显著高于对照组,而尿钾低于对照组(P<0.05)。表明长期饮用砖茶会影响体内Al和Ca等生命元素的代谢,其机理需进一步深入研究。In brick-tea fluorosis affected areas XiLinHot city in Irmer Mongolia, herdsmen who like drinking a large amount of brick tea in everyday life and Han habitants rarely drinking brick tea as control group were enrolled, and their hair and urine were sampled. The concentrations of Ca, Mg, K, Al, P, Cu, Zn and Fe in hair and urine were detected using ICP-OES. The RSDs of the method were between 2.32% and 8. 03%, and the analytical results of the hair reference samples were consistent with the certified values. The results showed that the contents of Al, Mg and K in hair, and contents of Al and Ca in urine of herdsmen who were accustomed to drinking brick tea were obviously higher than those in control group （P〈（0.05）, while the contents of K in urine of herdsmen who were accustomed to drinking brick tea was lower than those in control group （P〈0. 05）, and other elements did not have statistic significance （P〉0. 05）. Chronically drinking brick tea probably brings metabolic disorder of Ca and AI in human body, and the interaetion mechanism of life elements in brick-tea fluorosis should be further studied.
