摘　　要：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IAST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 20-40 years 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.
