调查了化工系统有毒作业岗位工人及退休工人 5 331人连续三年的年均发病率、死亡率和人均因病缺勤日。结果表明 ,5 6～ 6 5岁男、女和 6 6岁以上女性的发病率高于对照组 ,6 6岁以上女性死亡率高于对照组。其中测定 12 4名工人的全血超氧化物岐化酶 (SOD)活性和血清过氧化脂质 (LPO)含量 ,发现5 6～ 6 5岁的SOD活性低于对照组 ,而 46岁以上LPO含量则高于对照组 ,说明长期接触有毒物质可能会加速人体的衰老 ,有毒作业对工人衰老的影响不容忽视
Investigated the annual average morbidity, mortality and per-capita absence due to illness of 5 331 workers and retired workers in the chemical system for toxic work posts for three consecutive years. The results showed that the incidence of males, females and females aged 6 6 years old aged 56 to 65 years was higher than that of the control group, and the mortality rate of females aged 6 to 6 years was higher than that of the control group. Among them, SOD activity and serum lipid peroxidation (LPO) levels in 12 4 workers were determined. The SOD activity of 56 to 65 years old was lower than that of the control group, while LPO Content is higher than the control group, indicating that long-term exposure to toxic substances may accelerate the aging of the human body, the impact of toxic operations on the aging workers can not be ignored
