本文对某烟叶复烤厂１０５名接尘工人与同一地区不接触尘毒的１０１名对照工人进行了班前、班中肺功能测定的比较分析。接尘组男女工人班中测定的ＦＶＣ、ＦＥＶ＿１，ＭＭＦ、Ｖ＿（５０）平均值较班前明显降低，其差值具有显著或非常显著的意义。与对照组相比，接尘组男女工人肺功能各项指标的异常急性改变率明显增高，具有显著或非常显著的统计学意义。接尘组班前测定的肺功能各项指标实测值占预计值％均较对照组为低，其中男工的ＦＶＣ与ＦＥＶ＿１，女工的ＦＶＣ、ＦＥＶ＿１、ＭＭＦ与Ｖ＿（５０）均具有显著或非常显著的统计学意义。
In this paper, 105 smoke workers in a redrying factory of tobacco and 101 control workers in the same area not exposed to dust poisoning were analyzed comparatively. The average values of FVC, FEV_1, MMF and V_ (50) in men and women workers exposed to dust group were significantly lower than those before the shift, and the difference was significant or very significant. Compared with the control group, the abnormal acute change rate of pulmonary function indicators of male and female workers in Jiefang group were significantly increased, with significant or very significant statistical significance. The measured value of each index of lung function measured before taking the dust group was lower than that of the control group, and the male workers ’FVC and FEV_1, female workers’ FVC, FEV_1, MMF and V_ (50) had significant or abnormal Significant statistical significance.
