珍珠中的微量元素有其特征规律及作用。前人很早就关注到淡水珍珠和海水珍珠微量元素特征的差异，但限于测试技术及分析方法，测出的微量元素种类相当有限，并且对测试结果也缺乏深入分析。电感耦合等离子体质谱议（ICP-MS）具有检测能力高，速度快，可同时测试多种痕量及超痕量元素。采用ICP-MS对淡水和海水养殖珍珠的微量元素进行测定，并通过数据处理方法分析，对比。结果表明：（1）珍珠中含量较高的微量元素种类（Sr ，Zn ，Ni ，Ba ，Mn ，Cr ，Cu ，Pb ，Ti ，Co ，Ce ，Zr ，La ，Rb）大致相同，但淡水养殖珍珠的微量元素总量明显少于海水养殖珍珠；（2）淡水养殖珍珠的微量元素含量较为规律，具有较为固定的含量序列，即Sr＞Mn＞Ba＞Ni＞Cr＞ Pb；而海水养殖珍珠的微量元素含量差异较大，除了各样品都最富集Sr元素外，没有明显的含量顺序；（3）珍珠中某些微量元素之间存在显著相关性。结论对养殖珍珠的环境指示，养殖技术，鉴定，以及综合开发利用具有一定的指导意义。

Trace elements in pearls have characteristic disciplines and functions .The previous work had paid attention to different characteristics of trace elements in freshwater and seawater cultured pearls ,but only lim-ited species of trace elements have been detected by former testing techniques and analysis methods ,and the test results have not been further analyzed .With the advantages of detection in good capability and high speed , inductively coupled plasma mass spectrometer (ICP-MS) can concurrently test various trace and ultra-trace ele-ments .In the present paper ,trace elements of cultured pearls in freshwater and seawater were measured by ICP-MS ,and analyzed compared by a method of data processing .The results show that :(1) The kinds of higher content of trace elements (Sr ,Zn ,Ni ,Ba ,Mn ,Cr ,Cu ,Pb ,Ti ,Co ,Ce ,Zr ,La ,Rb)in cultured pearls are approximately the same ,but the total amount of trace elements in freshwater cultured pearls is sig-nificantly less than that of seawater cultured pearls .(2) The content of trace elements (Sr ,Mn ,Ba ,Ni ,Cr , Pb) in freshwater cultured pearls is more regular ,and has a relatively fixed sequence from high to low ,namely Sr>Mn>Ba>Ni>Cr>Pb .The content of trace elements in seawater cultured pearls is quite different .Sr is enriched in all samples .There is no a stable order of contents for the other trace elements .(3) There is a sig-nificant correlation among some trace elements in cultured pearls .The conclusion is instructive to indicate cul-tured environment ,cultured technology ,identification ,comprehensive development and utilization of cultured pearls .
