目的:了解山东省汽车制造企业职业病危害现状。方法:于2019年2至5月，采用方便抽样方法，以山东省20家汽车制造企业为调查对象，进行现场职业卫生调查，对工作场所职业病危害因素定点和个体接触水平进行检测，并分析作业人员职业健康检查结果。结果:20家汽车制造企业中，小型企业13家，中型企业4家，大型企业3家；工作场所苯和甲苯检测结果符合职业接触限值，电焊烟尘、锰及其化合物和二甲苯超过职业接触限值。工作场所空气中电焊烟尘短时间接触浓度（n CSTE）最大值为24.23 mg/mn 3，超标率为11.0%（16/146）；作业人员电焊烟尘时间加权平均浓度（n CTWA）最大值为10.60 mg/mn 3，超标率为11.0%（8/73）；工作场所空气中锰及其化合物n CSTE最大值为0.879 mg/mn 3，超标率为9.2%（11/120），作业人员锰及其化合物n CTWA最大值为0.175 mg/mn 3，超标率为5.7%（4/70）；工作场所空气中二甲苯n CSTE最大值为230.00 mg/mn 3，超标率为3.9%（2/51），作业人员二甲苯n CTWA最大值为70.40 mg/mn 3，超标率为3.6%（1/28）。4 775名接触职业危害因素的作业人员中，疑似电焊工尘肺38人（0.80%），疑似锰中毒27人（0.57%），疑似低浓度苯及苯系物慢性中毒31人（0.65%）。中、小型企业作业人员疑似职业病检出率较高，分别为2.86%（30/1 048）和4.51%（51/1 132）。不同规模汽车制造企业作业人员各疑似职业病检出率差异有统计学意义（n P<0.05）。n 结论:山东省汽车制造企业焊接作业岗位的电焊烟尘、锰及其化合物和喷漆作业岗位的二甲苯接触水平超标较严重，应加强职业卫生工作的监督管理，改善作业环境，保障焊接及喷漆作业人员的身体健康。“,”Objective:To investigate the current situation of occupational hazards in automobile manufacturing enterprises in Shandong Province.Methods:From February to May 2019, the convenience sampling method was adopted to conduct on-site occupational health surveys with 20 automobile manufacturing enterprises in Shandong Province as the survey subjects, to detect the occupational hazard factors in the workplaces and individual exposure levels, and to analyze the occupational health check results of operators.Results:There were 13 small-sized, 4 medium-sized and 3 large-sized enterprises among the 20 automobile manufacturing enterprises. The detection results of benzene and toluene in the workplaces met the occupational exposure limits, and the detection results of welding fumes, manganese and its compounds, and xylene exceed the occupational exposure limits. The maximum short-term exposure concentration (n CSTE) of welding fume in the air of workplaces was 24.23 mg/mn 3, and the over-standard rate was 11.0% (16/146) . The maximum time-weighted average concentration (n CTWA) of welding fume of operators is 10.60 mg/mn 3, and the over-standard rate was 11.0% (8/73) . The maximum n CSTE of manganese and its compounds in the air of workplaces was 0.879 mg/mn 3, and the of manganese and its compounds of operators was 0.175 mg/mn 3, and the over-standard rate was 5.7% (4/70) . The maximum xylene n CSTE in the air of workplaces was 230.00 mg/mn 3, and the over-standard rate was 3.9% (2/51) . The maximum xylene n CTWA of operators was 70.40 mg/mn 3, the over-standard rate was 3.6% (1/28) . Among the 4775 workers exposed to occupational hazards, 38 (0.80%) were suspected of electric welder's pneumoconiosis, 27 (0.57%) were suspected of manganese poisoning and 31 (0.65%) were suspected of chronic low-concentration benzene and benzene series poisoning. The detection rates of suspected occupational diseases among workers in small and medium-sized enterprises were relatively high, 2.86% (30/1048) and 4.51% (51/1132) respectively. There was a statistically significant difference in the detection rates of suspected occupational diseases among the operators of different scale automobile manufacturers (n P<0.05) .n Conclusion:The exposure levels of electric welding fumes, manganese and its compounds in welding jobs and xylene exposure levels in spray painting jobsin Shandong Province's automobile manufacturing enterprises are more serious. The supervision and management of occupational hygiene should be strengthened, the working environment should be improved, and the health of welding and painting workers should be protected.
