建立微波消解-电感耦合等离子体质谱法（ICP/MS）测定背瘤丽蚌和鳙鱼体内8 种微量元素，样品加入HNO3+H2O2（3+1）经微波消解、使用ICP-MS进行测定，引入Ge、In、Bi、Sc内标物质克服质谱干扰，并优化仪器参数。Fe、Cu、Zn、Mn、Cd、Pb、As、Hg 的方法检出限分别为2.3、0.5、1.1、0.4、0.6、0.5、1.0、1.8 μg/L，相关系数均在0.9993以上，方法回收率在80.4~101.2%之间，相对标准偏差小于6.29%；实际样品分析发现背瘤丽蚌体内富含Fe、Zn，而Pb、Cd、Hg等潜在危害元素亦同时存在。

A method of microwave digestion-ICP/MS was established to determinate 8 kinds of trace element in mussel and bighead tissue. The sample was added with HNO3+H2O2 (3+1) after microwave digestion before ICP-MS determination. The introduction of Ge, In, Bi, Sc as internal standard substance can avoid spectral interferences, and the parameters of the apparatus was optimized. The detection limits of Fe, Cu, Zn, Mn, Cd, Pb, As and Hg were 2.3, 0.5, 1.1, 0.4, 0.6, 0.5, 1 and 1.8 μg/L, respectively, with the correlation coefficient higher than 0.9993. The recovery rate and relative standard deviation were 80.4~101.2% and less than 6.29%, respectively. The analysis of Lamprotula leai samples showed that Lamprotula leai was rich in Fe, Zn. However, several potentially harmful elements, such as Pb, Cd and Hg were also exist in the samples.
