印刷包装行业VOCs污染对工人体内抗氧化指标的影响

Effect of pollutants of press-pack industry on antioxidants level of worker

目的研究印刷包装行业VOCs污染对工人体内抗氧化指标的影响。方法使用紫外-可见分光光度法和荧光光度法测定从业工人血清超氧化物歧化酶(SOD)活性、组织抗氧化能力(GSHPxLPO)、维生素C(VC)、维生素E(VE)含量。结果印刷包装工人血清中SOD活力为(112.58±16.56)Uml,高于正常对照组(P<0.01);组织抗氧化能力为(105.43±63.87)Uml,VC含量为(15.46±9.05)μgml均低于对照组(P<0.01),VE含量为(7.6±3.16)μgml与对照组相比差异无显著性。结论印刷包装行业存在的VOC污染导致从业工人的抗氧化水平降低。

Objective To study the differences in antioxidants level （SOD, GSH-PX, LPO, VC, VE） between the male workers who worked to volatile benzene compounds in printing factory and the male workers who were not for evaluating the effect of pollution of volatile benzene compounds in printing industry. Methods SOD, GSH-PX, VC were measured as ultraviolet visible spctrophotometry （UV）. LPO, VE were measured as molecular fluorescence spectroscopy. Data of 43 male workers exposed to benzene toluene and xylene and control group of 50 were analyzed by SPSS 11.0. Results The exposed workers were significantly different with controls in SOD, GSH-PX/ LPO, VC （ P 〈 0.05） but not in VE （ P 〉 0.05）. Conclusion The Antioxidants level of male printing workers could be affected by exposure to pollution of volatile benzene compounds in printing industry.
