In the present study, a method for the determination of mercury (Hg) in fish was validated according to ISO/IEC 17025, INMETRO (Brazil), and more recent European recommendations (Commission Decision 2007/333/EC and 2002/657/EC) for implementation in the Brazilian Residue Control Plan (NRCP) in routine applications. The parameters evaluated in the validation were investigated in detail. The results obtained for limit of detection and quantification were respectively, 2.36 and 7.88 μg kg(-1) of Hg. While the recovery varies between 90-96%. The coefficient of variation was of 4.06-8.94% for the repeatability. Furthermore, a comparison using an external proficiency testing scheme was realized. The results of method validated for the determination of the mercury in fish by Hydride generation atomic absorption spectrometry were considered suitable for implementation in routine analysis.
在本研究中，根据 ISO/IEC 17025、巴西 INMETRO 和最近的欧洲建议（委员会第 2007/333/EC 和 2002/657/EC 号决定），验证了一种用于测定鱼类中汞（Hg）的方法，以在巴西残留控制计划（NRCP）中进行常规应用。详细研究了验证中评估的参数。检测限和定量限的结果分别为 2.36 和 7.88μgkg(-1)的 Hg。而回收率在 90-96%之间变化。重复性的变异系数为 4.06-8.94%。此外，还使用外部能力验证计划进行了比较。结果表明，采用氢化物发生原子吸收光谱法测定鱼类中的汞，该方法适用于常规分析。
