目的比较磨工粉尘对作业工人肺功能的影响。方法对147名磨工粉尘作业工人和89名对照组进行了通气功能测定。结果接触组的VC、FVC、MMEF、FEY1.0、FEY1.0/FVC%等指标的实测值及实测值占预计值的比值均校对照组低,且多具有统计学意义。结论长期接触磨工粉尘可引起肺通气功能的改变。
Objective To compare the effect of mill worker dust on lung function of workers. Methods Ventilatory function was measured in 147 workers who grind workers and 89 control workers. Results The values of VC, FVC, MMEF, FEY1.0, FEY1.0 / FVC% and other indexes in the exposure group were all lower than those in the control group, and were statistically significant. Conclusion Long-term exposure to mill dust can cause changes in pulmonary ventilation.
