目的监测河南省某金矿选矿厂的职业病危害因素现状及其对工人健康的影响,为加强职业健康监护和劳动防护措施提供依据。方法按照GBZ159-2004的采样要求进行采样;按照GBZ/T 192-2007对粉尘进行检测;按照GBZ/T189.8-2007对噪声进行检测,分析工作场所中职业病危害因素对劳动者健康的影响。结果该厂下料工、破碎工、皮带工作业场所中粉尘浓度分别为2.1、5.8和6.8 mg/m3,超出GBZ 2.1-2007的要求;破碎工、皮带工、球磨工、浮选工作业场所中噪声强度分别为94.2、92.8、91.9和90.8 dB(A),超出GBZ 2.2-2007的要求;职业健康检查项目中B超(肝脏损伤)、心电图、胸片、血常规异常率分别为11.6%、9.3%、2.3%和4.6%。结论该厂职业病危害因素超标严重,对劳动者健康有一定的影响;整体防护和个体防护需进一步加强和重视。
Objective To monitor the status quo of occupational hazards and the impact on workers’ health in a gold ore dressing plant in Henan Province, and provide the basis for strengthening occupational health monitoring and labor protection measures. Methods The samples were sampled according to the sampling requirements of GBZ159-2004, the dust was tested according to GBZ / T 192-2007, the noise was tested according to GBZ / T189.8-2007, and the impact of occupational hazards in workplaces on workers’ health was analyzed. Results The concentration of dust in the workers, crusher and belt workers in the factory was 2.1, 5.8 and 6.8 mg / m3, respectively, exceeding the requirements of GBZ 2.1-2007; crushing, belt workers, ball mill workers and flotation workers The noise intensity in the occupational health examination items were 94.2,92.8,91.9 and 90.8 dB (A), respectively, exceeding the requirements of GBZ 2.2-2007. The abnormalities of B-ultrasonography (liver damage), electrocardiogram, chest radiograph and blood routine in occupational health examination were 11.6% , 9.3%, 2.3% and 4.6% respectively. Conclusion The plant occupational hazards are over-standard and have a certain impact on workers’ health. The overall protection and individual protection need to be further strengthened and valued.
