本文测定了宁夏农村地区回汉族人群血清中Li、Co、Cd、Ga、Ba、Sr、Cu、Zn、Fe、Al、Se、Sn、B、Mn、Cr、Ni、Pb、Ca、K、Mg、Na、P、S的含量。采用微波消解对样品进行了前处理,使用电感耦合等离子体原子发射光谱法( ICP-AES)进行测定。该方法的RSD≤3．5%,样品加标回收率为90%~117%。该法简便、快速、灵敏、准确,可用于血清中多种元素含量的同时测定。研究结果表明,K、Fe、Cu、Mn、Ni、Ga、Al、Se、Pb、S、Cd、Cr、Sr、Ca这14种元素含量在回族和汉族之间存在着显著性差异(P<0．05),探讨了产生上述差异的原因。

The concentration of serum mineral elements of rural residents in Ningxia was determined by ICP-AES in this work. Microwave digestion was used for sample decomposition. By this way, RSD≤3. 5%and the average recoveries were in the range of 90%-117%. The method is simple,rapid,sensitive and accurate for the determination of various elements in the same ser-um. The results show that,there are significant difference between Hui ethnic group and Han ethnic group in 14 elements(P<0. 05) . At the same time,the reasons which caused differences were explained.
