目的　探讨焦炉逸散物对作业工人肺功能及呼吸系统症状的影响。方法　按吸烟指数、年龄、身高和体重配对 ,对焦炉工和对照组进行问卷调查、肺功能测定和焦炉逸散物累积接触剂量 (指数 )估算。结果　接触组肺功能FVC、FEV1 0 、MMF、FEF2 5% 、FEF50 % 、FEF75% 和各项肺功能实测值占预计值百分比均明显低于对照组 (P <0 0 5或P<0 0 1)。焦炉工咳嗽、咳痰阳性率随累积接触剂量的增加而升高 (P <0 0 5 ) ;累积接触剂量≥ 60 0 0时 ,各项肺功能指标异常率明显高于对照组 (P <0 0 5 )。结论　焦炉逸散物可引起肺功能的降低和呼吸系统异常症状发生率升高。 Objective To investigate the effects of coke oven fugitives on lung function and respiratory symptoms in workers. Methods According to the smoking index, age, height and weight pairing, the coke oven workers and the control group were surveyed, the pulmonary function test and cumulative exposure dose (index) of coke oven were estimated. Results The percentage of FVC, FEV1 0, MMF, FEF2, FEF50% and FEF75% in the exposure group were all significantly lower than those in the control group (P <0 05 or P 0 01 ). The positive rate of cough and expectoration of coke oven workers increased with the increase of cumulative exposure dose (P <0.05). When the cumulative exposure dose was 60 000, the abnormal rate of various pulmonary function indexes was significantly higher than that of the control group (P < 0 0 5). Conclusion Coke oven fugitives can cause decreased lung function and respiratory abnormalities increased.
