In this study, trace element contents of animal tissues were determined by atomic absorption spectrometry after microwave digestion method. The accuracy of the method was confirmed by analysis of standard reference material (NIST SRM 1577b Bovine Liver). Trace element contents in animal tissue samples were found in the range of 98.3-18.2 μg/g (Fe), 2.89-0.26 μg/g (Mn), 23.9-4.54 μg/g (Zn), 0.08-0.01 μg/g (Pb), 32.9-1.66 μg/g (Cu), and 0.32-0.01 μg/g (Cd). The results were compared with literature values. The results obtained for toxic and trace elements in analyzed animal tissue samples were acceptable to human consumption at nutritional and toxic levels.
本研究采用微波消解法，通过原子吸收光谱法测定动物组织中的微量元素含量。通过对标准参考物质（NIST SRM 1577b 牛肝）的分析，验证了该方法的准确性。动物组织样品中的微量元素含量范围为 98.3-18.2μg/g（Fe）、2.89-0.26μg/g（Mn）、23.9-4.54μg/g（Zn）、0.08-0.01μg/g（Pb）、32.9-1.66μg/g（Cu）和 0.32-0.01μg/g（Cd）。将结果与文献值进行了比较。在所分析的动物组织样品中，有毒和微量元素的含量在营养和毒性水平上均适合人类食用。
