摘要
本文对某皮毛厂93名接尘工人与101名对照工人进行了班前、班中肺功能测定的比较分析。接尘组工人班中测定的肺功能平均值多较班前为低,其中男工的MMF、V75、V50等指标的差值具有统计学意义。与对照组相比,接尘组男工的MMF、V75、V50等指标班中与班前差值的平均值具有非常显著意义的差别;接尘组工人肺功能急性改变率较对照组明显增高,其中FVC、MMF与V50具有非常显著的意义。接尘组与对照组急性改变率比较,P<0.01讨论关于皮毛粉尘对工人肺功能急性影响的研究,迄今文献报道甚少。Zuskin等曾于1976年对从事毛尘作业工人肺功能的急性影响进行了研究,结果表明,FEV1、V50班后较班前明显下降,前者下降3%左右,后者下降10%左右,FVC未见有意义的变化[6]。国内尚未见有关皮毛尘对工人肺功能急性影响的研究报道。本文调查结果表明,接尘组班中测定的肺功能平均值多较班前为低,且其中男性工人班前与班中MMF、V75、V50等指标测定值的差值具有显著或非常显著的统计学意义。接尘组与对照组相比,除FVC及女工的FEV1及V75外,其他各项指标班前与班中差值的平均值,均以接尘组为高,其中,男性工人的MMF、V75、V?
Lung functions of 93 furriers and 101 controls were measured before and after shift.Average level of lung functions after shift was lower than those before shift in exposed workers.MMF,V75,V50 of male exposed workers lowered significantly.Lowering level of lung functions(MMF,V75,V50)after acute exposure in male exposed workers was significantly higher than those of male control workers.Acute change rates of lung functions(FVC,MMF,V50)in exposed workers were significantly higher than those of control workers.
