目的 了解工作场所中极低频电磁场的暴露水平,分析极低频电磁辐射对从业人员健康状况的影响.方法 使用EFA-300工频电磁场场强测试仪测量某工厂的2个不同车间(对照组与暴露组)的电场强度和磁感应强度,同时使用AWA5610D型积分声级计测量噪声.共收集到188名对照组和642名暴露组作业人员近期的体检资料.结果 暴露组车间电场强度(中位数为1.65 Wm),磁感应强度(中位数为0.51 μT)明显高于对照组(中位数分别为0.50 V/m、0.07 μT),差异均有统计学意义(P＜0.01)；暴露组车间噪声强度为86.72dB(A),对照组为90.75dB(A),差异无统计学意义(P＞0.05).暴露组血清中同型半胱氨酸、丙氨酸转氨酶、天冬氨酸转氨酶、谷氨酰转移酶、心电图的异常率(分别为41.9％、32.8％、13.5％、28.4％、21.1％)明显高于对照组(分别为22.4％、18.7％、4.1％、18.7％、5.7％),差异均有统计学意义(P＜0.05或P＜0.01).结论 极低频电磁辐射暴露可能会对作业人员心血管系统带来一定影响.

Objective To observe the exposure levels of extremely low frequency electromagnetic fields in workplaces and to analyze the effects of extremely low frequency electromagnetic radiation on cardiovascular system of occupationally exposed people.Method Intensity of electromagnetic fields in two workplaces (control and exposure groups) was detected with EFA-300 frequency electromagnetic field strength tester,and intensity of the noise was detected with AWA5610D integral sound level.The information of health physical indicators of 188 controls and 642 occupationally exposed workers was collected.Data were analyzed by SPSS17.0 statistic software.Results The intensity of electric fields and the magnetic fields in exposure groups was significantly higher than that in control group (P＜0.05),but there was no significant difference of noise between two workplaces (P＞0.05).The results of physical examination showed that the abnormal rates of HCY,ALT,AST,GGT,ECG in the exposure group were significantly higher than those in control group (P＜0.05).There were no differences of sex,age,height,weight between two groups (P＞0.05).Conclusion Exposure to extremely low frequency electromagnetic radiation may have some effects on the cardiovascular system of workers.
