摘　　要：探讨了微波消解后利用ICP-OES测定塑料中镉、铬、汞、铅含量的不确定度来源。结果显示了几个最主要的不确定度来源,当镉、铬、汞、铅含量分别为34.83 mg/kg,472.8 mg/kg,394.0 mg/kg和263.8 mg/kg时,对应的扩展不确定度分别为0.872 mg/kg,10.6 mg/kg,10.4 mg/kg和5.73 mg/kg。The uncertainty evaluation method of Pb,Hg,Cd and Cr in plastics by ICP-OES was discussed. evaluated. The results showed that the major sources of measurement uncertainty. When Cd,Cr,Hg and Pb were 34. 83 mg/kg,472. 8 mg/kg,394. 0 mg/kg and 263. 8 mg/kg,the combined relative standard uncertainty were 0. 872 mg/kg、10. 6 mg/kg、10. 4 mg/kg and 5.73 mg/kg.
