依据欧盟EU 10-2011《关于预期与食品接触的塑料材料和制品的委员会法规》，建立了电感耦合等离子体质谱法测定食品接触塑料的迁移金属。选择同位素分别为：138Ba、59Co、63Cu、57Fe、7Li、55Mn、66Zn，并采用在线内标法，同时用反应池模式去除ArO+对铁离子的干扰。7种元素分别在一定浓度范围内呈线性，检出限为0.006-0.789μg/L，定量限为0.02-2.63μg/L，线性相关系数大于0.999。对于食品模拟物3%乙酸采用直接进样的方法进行检测，50%乙醇和橄榄油采用微波消解的方法进行处理，7种元素的回收率为93.0%-109.8%，相对偏差为5.6%-8.4%。

The method of the determination of harmful metals in food simulates, which were mentioned in EU10-2011, by inductively coupled plasma mass spectrometry (ICP-MS) was proposed. The isotopes (138Ba,59Co,63Cu,57Fe,7Li, 55Mn,66Zn) were selected and internal standard method were used. Dynamic collision reaction cell (DRC) was used to overcome ArO+. Linear relationships of the 7elements were kept in definite ranges, with the LOD in the ranges of 0.006-0.789μg/L and the LOQ in the ranges of 0.02-2.63μg/L. Food simulates of 50%alcohol and olive oil were pretreated by microwave assisted digestion. Values of recovery and RSD’s were found in the range of 93.0%-109.8%and 5.6%-8.4%respectively.
