印刷业重金属污染对工人微量元素水平的影响

目的研究印刷业中重金属污染因素对人体健康的危害。方法采集印刷包装作业工人和非作业人群的头发、血清样品,用电感耦合等离子体原子发射光谱仪(ICPS-7000)测定锰(Mn)、铅(Pb)、铬(Cr)、铜(Cu)和锌(Zn)的质量浓度。结果印刷车间工人血清中Cr、Mn、Cu的质量浓度明显高于非作业人群(P<0.05),血Zn质量浓度明显降低(P<0.05);头发中Cr、Mn的含量明显高于非作业人群(P<0.05),发Cu和Zn含量明显降低(P<0.05);2组人群血Pb和发Pb含量的差异无统计学意义(P>0.05)。结论印刷业重金属污染可能对从业工人体内微量元素水平产生影响。

Effect of Heavy Metal Pollution on the Levels of Trace Elements in the Hair and Serum of Printing Workers

Objective To study the changes of the level of trace elements in the hair and serum of printing workers,who might have been exposed to heavy metals.Methods Hair and serum were collected from both printing workers(printing worker group),and workers not related in printing industry(control group).The concentration of manganese,lead,chrome,copper and zinc were determined by the inductance-coupling plasma atom emission spectrum method.Results The manganese and copper levels in the serum of the printing worker group were exceeded in relation to the control group(P<0.05).The level of zinc in serum of printing worker group was much higher than those in control group(P<0.05).The levels of chrome and manganese in hair of printing worker group were much higher than those in control group(P<0.05).The levels of zinc and copper in hair of printing worker group were much lower than those in control group(P<0.05).The lead level in serum and hair did not show any significant difference between printing worker and control group.Conclusion Exposure to heavy metals affects the levels of some trace elements in the hair and serum of printing workers.
