Respiratory function was studied in a group of 29 soy workers exposed to soy bean dust produced after extraction of soy oil. The prevalence of all chronic respiratory symptoms was consistently higher in exposed than in control workers, although the differences were not statistically significant. During the Monday work shift there was a significant mean acute across-shift decrease in maximum expiratory flow rates at 50% and 25% vital capacity (FEF50: -6.4%; FEF25: -12.4%). Changes in vital capacity (FVC: -3.6%) and 1-sec forced expiratory volume (FEV1: -2.7%) were smaller, but still statistically significant. There were also statistically significant acute reductions in all ventilatory capacity parameters over the work shift on the following Friday, although the changes were in general smaller than on Monday (except for FEV1). An analysis of Monday preshift values of ventilatory capacity in soy bean workers suggests that exposure to soy bean dust may lead to chronic respiratory impairment in some workers.
对一组29名接触豆油提取后产生的大豆粉尘的大豆加工工人的呼吸功能进行了研究。尽管差异无统计学意义，但接触组所有慢性呼吸道症状的患病率始终高于对照组工人。在周一的工作班次中，在肺活量的50%和25%时的最大呼气流量率出现了显著的平均跨班次急性下降（FEF50：-6.4%；FEF25：-12.4%）。肺活量（FVC：-3.6%）和1秒用力呼气量（FEV1：-2.7%）的变化较小，但仍具有统计学意义。在接下来的周五工作班次中，所有通气能力参数也出现了统计学上的显著急性下降，尽管总体变化比周一小（FEV1除外）。对大豆加工工人周一班前通气能力值的分析表明，接触大豆粉尘可能会导致一些工人出现慢性呼吸功能损害。
