Dust exposure is high in several industries. We investigated associations of exposure in paper mills, wood pellet plants, and iron foundries with lung function impairment.
Respirable silica, inhalable paper dust, or inhalable wood dust were collected as personal samples and spirometry was performed. Multiple linear regression analyzed associations with FEV 1 %pred and FVC%pred.
Wood pellet workers with high exposure to inhalable dust had lower FEV 1 %pred (95% CI) (-9.4 [-16 to -2.6]) and FVC%pred (-9.8 [-15 to -4.0]) compared with lowest exposure level. Workers at paper mills and foundries had no dose-dependent association but lower FEV 1 %pred and FVC%pred than in workers at wood pellets plants.
Increased exposure to inhalable wood dust is associated with decreased lung function. Foundry and paper mill workers have generally lower lung function than wood pellet workers. Spirometry should be considered in workers in industries with airborne particulate matter pollution.
在一些行业中，粉尘暴露水平较高。我们研究了纸浆厂、木屑颗粒厂和铸造厂的粉尘暴露与肺功能损害之间的关系。
采集可呼吸性二氧化硅、可吸入性纸尘或可吸入性木尘作为个人样本，并进行肺活量测定。多线性回归分析与 FEV 1 %pred 和 FVC%pred 的相关性。
与最低暴露水平相比，高暴露于可吸入性粉尘的木屑颗粒厂工人的 FEV 1 %pred（95%CI）（-9.4[-16 至-2.6]）和 FVC%pred（-9.8[-15 至-4.0]）更低。纸浆厂和铸造厂的工人没有剂量依赖性关联，但 FEV 1 %pred 和 FVC%pred 均低于木屑颗粒厂的工人。
可吸入性木尘暴露增加与肺功能下降有关。与木屑颗粒厂工人相比，铸造厂和纸浆厂工人的肺功能通常较低。在空气中存在颗粒物污染的行业中，应考虑对工人进行肺活量测定。
