摘要
本文对沈阳某重型机器厂铸钢车间２５９名接尘工人与７４名调离铸钢粉尘作业工人进行了肺功能与呼吸系统症状的配对分析。结果表明：无论是接尘工人，还是调离粉尘作业工人，其ＦＶＣ、ＦＥＶ１、ＦＥＦ２５－７５％、Ｖ７５、Ｖ５０等肺功能指标的实测值均较对照组明显降低，肺功能异常人数以及呼吸系统症状阳性人数与慢性支气管炎的患病人数则较对照组显著升高。
ased on age,height and smokinghabits,259 steel foundry workers who
hadbeen employed for 19 years in average and 74workers who had been removed from
expo-sure to steel foundry dust for 10 years in av-erage were matched with control workers
re-spectively.Lung function tests and respirato-ry symptoms were investgated in both
twomatched groups FVC、FEV1、FEF25-75%、V75and V50 in either current foundriers or
ex-foundriers were significantly decteased thanthose in their parallel control workers. Therates
of lung dys-function in current foundri-ers and exfoundriers were signifcantly higherthan those
in control workers. Both currentfoundriers and exfoundriers showed higherprevalence of
repiratory symptoms and Chron-ic brochitis than their parallel control group.
