The lung function impairment is the most common respiratory problem in industrial plants and their vicinity. Therefore, the purpose was to study the affects of wood dust and its duration of exposure on lung function. This was a matched cross-sectional study of Spirometry in 46 non-smoking wood workers with age range 20 - 60 years, who worked without the benefit of wood dust control ventilation or respiratory protective devices. Pulmonary function test was performed by using an electronic Spirometer. Significant reduction was observed in the mean values of Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), and Maximum Voluntary Ventilation (MVV) in wood workers relative to their matched controls. This impairment was increased with the duration of exposure to wood industries. It is concluded that lung function in wood workers is impaired and stratification of results shows a dose-response effect of years of wood dust exposure on lung function.
肺功能损害是工厂及其周边地区最常见的呼吸问题。因此，本研究旨在探讨木尘及其暴露时间对肺功能的影响。这是一项配对横断面研究，对46名年龄在20至60岁之间的不吸烟木工进行肺活量测定，这些工人在没有木尘控制通风或呼吸防护设备的情况下工作。使用电子肺活量计进行肺功能测试。与匹配的对照组相比，木工的用力肺活量（FVC）、一秒用力呼气量（FEV1）和最大自主通气量（MVV）的平均值显著降低。这种损害随着接触木材行业的时间延长而增加。得出的结论是，木工的肺功能受到损害，结果分层显示木尘暴露年限对肺功能有剂量反应效应。
