A lung function study was carried out to determine the relative effect of rice husk and saw dust on mill workers. The study consisted of 195 subjects of which 56 rice mill workers, 71 saw mill workers and 68 controls of similar age, sex and socio-economic condition. FVC was significantly reduced in saw-mill workers compared to both the controls and rice mill workers. Both FEV1 and PEFR/min were significantly reduced in both mill workers compared to controls. The fall in PEFR/min in saw mill workers was also significant when compared to rice mill workers. FVC was reduced after 5 years of exposure only in saw mill workers. FEV1 was reduced within a year which was further reduced after 5 years in both mill workers. PEFR/min was highly reduced within a year remained so even after 5 years.
开展了一项肺功能研究,以确定稻壳和锯末对磨坊工人的相对影响。该研究包括195名受试者,其中56名碾米厂工人、71名锯木厂工人以及68名年龄、性别和社会经济状况相似的对照者。与对照者和碾米厂工人相比,锯木厂工人的用力肺活量(FVC)显著降低。与对照者相比,两类磨坊工人的第一秒用力呼气容积(FEV1)和每分钟呼气峰值流速(PEFR/min)均显著降低。与碾米厂工人相比,锯木厂工人的PEFR/min下降也很显著。仅锯木厂工人在接触5年后FVC降低。FEV1在一年内降低,两类磨坊工人在5年后进一步降低。PEFR/min在一年内大幅降低,5年后仍保持如此。
