Abstract

Abstract:

The content of lead, cadmium, chromium and mercury was determined by inductively coupled plasma-mass spectrometry（ICP-MS） in 13 samples of printed paper as food packaging materials and in 3 corresponding non-printed paper samples, which were collected from domestic suppliers, and are 2.045—5880.261 μg·L^-1, 0.124—5.945 μg·L^-1, 2.464—1430.863 μg·L^-1 and 0.170—11.378 利用电感耦合等离子体-质谱法（ICP-MS）对从国内不同纸质食品包装材料供应商收集到的13种印刷纸质食品包装材料以及3种相对应未印刷纸样中重金属——铅（Pb）、镉（Cd）、铬（Cr）以及汞（Hg）的含量进行了分析，其中Pb 2.045～5880.261 μg·L^-1， Cd 0.124
