含锰电焊作业人员职业性听力损伤的调查研究

Investigation of occupational hearing loss in manganese-containing welding workers

  • 摘要:
      目的  通过对含锰电焊作业人员听力状况的调查,探讨含锰电焊作业产生的锰与噪声对听力损伤的联合作用。
      方法  选择某汽车制造企业接触噪声作业人员198人,按照职业病危害因素接触情况,分为单纯噪声接触组(66人)和电焊作业组(132人),对所有作业人员进行纯音听力测试及尿锰检测;对作业场所空气中的锰浓度和噪声声级进行检测,比较两组间纯音测听及噪声性听力损伤检出结果。
      结果  两组作业人员在年龄和接噪工龄方面差异无统计学意义(P> 0.05);电焊作业组2、3、4 kHz纯音听阈高于单纯噪声接触组(P < 0.01);电焊作业组检出噪声性听力损伤35例,检出率为26.5%;单纯噪声接触组检出噪声性听力损伤8例,检出率为12.1%,两组间检出率差异有统计学意义(P < 0.01)。
      结论  含锰电焊作业产生的化学有害因素可能与噪声在引起噪声性听力损伤方面存在联合作用,其中锰可能起了重要作用。

     

    Abstract:
      Objective  To investigate the combined effect of manganese exposure and noise on welding workers' hearing loss due to the use of electrodes containing manganese.
      Methods  A total of 198 noise-exposed workers from an automobile manufacturing company were selected and divided into two groups, namely the pure noise exposure group (n= 66) and the welding operation group (n= 132). Pure tone audiometry and urine manganese measurement were performed on all workers; the manganese concentration and noise level at the workplaces were measured, and the results of pure tone audiometry and noise-induced hearing loss detection between these two groups were compared.
      Results  There was no statistical difference in age and noise exposure time between these two groups (P> 0.05); the pure tone thresholds at 2, 3, and 4 kHz in the welding operation group were higher than those in the pure noise exposure group (P < 0.01); 35 cases of noise-induced hearing loss were detected in the welding operation group, with a detection rate of 26.5%; eight cases of noise-induced hearing loss were detected in the pure noise exposure group, with a detection rate of 12.1%, and the difference was statistically significant (P < 0.01).
      Conclusions  Manganese exposure due to manganese-containing welding operations may have a combined effect with noise to cause noise-induced hearing loss.
