摘　　要：测定大连地区海产贝类中微量元素的含量并对其进行分析。利用火焰原子吸收光谱法(FAAS)对大连市面所售的12种常见海产贝类中的锌、铁、铜、锰等微量元素进行了含量测定,并用加标回收法检验了该方法的可靠性。结果:1)海产贝类中富含锰、铁、锌、铜。2)同种贝类不同组织的微量元素含量存在显著差异。本实验方法简便、快速,易于操作,准确度高,并为人们通过食用贝类补充微量元素提供了理论依据。Determined trace elements Mn, Fe,Zn, Cu in twelve shellfish food samples which purchased in the market of Dalian by using atomic absorption spectrometry （FAAS）.The correctness of the method was verified by the recovery test.The results showed that there are abundant necessary elements like Mn, Fe, Zn, and Cu in the samples. We can get different trace elements by eating the shellfish. The method is proved to be simple, rapid, sensitive, precision and easy to operate.
