【摘要】 我们对北京焦化厂2,106人进行了恶性肿瘤死亡十一年回顾性调查。结果表明恶性肿瘤的标化死亡比和比例死亡比与对照组比较均有超出,炼焦车间超出量较大,表明其具有职业特点。但肺癌死亡率未显示明显高于对照组,可能与该厂职工工龄较短,环境污染程度较轻有关。更多还原

【Abstract】 A retrospective survey of the deaths caused by malignant tumor in 11 years was carried out at the Beijing Coking and Chemical Works. Both of the SMR and PMR of the mortality of malignant tumor among 2106 workers were excessive in comparison with control groups, particularly in the case of coking workshop where the SMR and PMR were the most excessive in the case of coke-oven workers in general and oven-top workers in particular. It indicated that the excess was characterized by occupation. But the lung cancer rate was not higher than that of control groups. The possible reason was the length of service is comparatively short in the case of workers at this works, and environmental pollution is comparatively slight.更多还原
