采用职业卫生现况调查和回顾性调查方法,对某使用氯乙烯企业工作场所中职业病危害因素检测结果、职业健康检查结果进行分析,并与国内同类企业进行对比。结果表明,氯乙烯浓度符合国家职业卫生标准限值要求,但在职业健康检查中检出高血压、白细胞减少、血清中谷丙转氨酶(ALT)升高、脂肪肝等异常人员。血清中ALT升高检出率呈逐年增加趋势,白细胞降低、脂肪肝、血清中ALT升高检出率均高于文献提供的对照人群。提示,长期接触低浓度氯乙烯也可能产生健康危害,应加强作业人员的健康教育,密切注意作业人员肝功能、血液系统状况,以达到保护工人健康的目的。
Using occupational health status survey and retrospective survey methods, the results of occupational hazards test and occupational health examination in a workplace using vinyl chloride enterprises were analyzed and compared with that of domestic counterparts. The results showed that the concentration of vinyl chloride in line with the national occupational health standards limit requirements, but in occupational health checks detected high blood pressure, leukopenia, elevated serum alanine aminotransferase (ALT), fatty liver and other abnormal staff. The detection rate of elevated ALT in serum showed an increasing trend year by year. Leukopenia, fatty liver, and elevated serum ALT were higher than those in the control group provided by the literature. It is suggested that long-term exposure to low concentrations of vinyl chloride may also cause health risks. Health education should be strengthened for operators and pay close attention to liver function and blood system conditions of workers so as to protect workers’ health.
