目的探讨极低频电磁场暴露对从业人员肝脏功能的影响.方法选择某厂作业人员作为职业人群研究对象.收集两组暴露组和一组对照组的近期体检资料.将年龄20～40岁、工龄2年以上的工人体检资料进行分析,根据接触电磁场强度,将相对较少暴露于电磁辐射作为暴露组Ⅰ (123名),较多暴露于电磁辐射作为暴露组Ⅱ(229名),不接触电磁辐射人员作为对照组(212名).比较各组直接胆红素、丙氨酸转氨酶(ALT)、碱性磷酸酶(ALP)、天冬氨酸转氨酶(AST)、谷氨酰转移酶(GGT)、白蛋白.采用EFA-300工频电磁场场强测试仪检测电磁场强度,采用AWA5610D型积分声级计检测噪声强度.结果电场和磁场结果显示,暴露组Ⅱ均高于暴露组Ⅰ.与对照组相比,暴露组Ⅰ AST高于对照组.暴露组ⅡALT、ALP、AST、GGT和白蛋白均明显高于暴露组Ⅰ与对照组,而直接胆红素明显低于暴露组Ⅰ和对照组.结论极低频电磁场的暴露可能对人体肝脏功能有一定影响.

Objective To examine the effect of exposure to extremely low-frequency electromagnetic fields (ELF EMFs) on the liver function of workers.Methods The workers in a factory were selected as subjects,and the recent physical examination data of these workers were collected.The workers aged 20～40years and with more than 2 years' working experience were included for analysis; considering the intensity of electromagnetic field,the workers exposed to less electromagnetic radiation were assigned to exposure Ⅰ group (n=123),those exposed to more electromagnetic radiation to exposure Ⅱ group (n=229),and those not exposed to electromagnetic radiation to control group (n=212).There were no significant differences in sex,age,height,and body weight between the three groups (P＞0.05).Physical examination,including measurements of direct bilirubin (DBil),alanine aminotransferase (ALT),alkaline phosphatase (ALP),aspartate aminotransferase (AST),γ-glutamyl transpeptidase (GGT),and albumin,was performed in a health examination center.The intensity of electromagnetic field was measured by EFA-300 power frequency electromagnetic field analyzer,and the intensity of noise by AWA5610D integrating sound level meter.Results The intensities of electric field and the magnetic field in exposure Ⅱ group were significantly higher than those in the exposure Ⅰ group.The levels of ALT,ALP,AST,GGT and albumin in exposure Ⅱ group were significantly higher than those in exposure Ⅰ group and control group.However,the level of direct bilirubin in exposure Ⅱ group was significantly lower than that in exposure Ⅰ group and control group.Conclusion Occupational exposure to ELF EMFs may affect human liver function.
