The objective of this study was to assess factors affecting lung function among 685 workers in the rubberwood (Hevea brasiliensis) furniture industry in the Chonburi and Rayung provinces of eastern Thailand. Study data were gathered using questionnaires, by sampling wood dust, and by spirometry. The mean wood dust exposure level in the factories was 4.08 mg/m3 (SD = 1.42, range: 1.15-11.17 mg/m3). The mean overall percent of predicted forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC values were 84 % (SD = 13.41), 86 % (SD = 14.40), and 99% (SD = 10.42), respectively. Significant negative correlations were found between mean dust exposure levels and FVC (p = 0.0008), and FEV1/FVC% (p < 0.001), but not FEV1 (p = 0.074). An association between decline in lung function and wood dust levels among wood workers suggests that rubberwood dust exposure negatively affects lung function.
本研究的目的是评估泰国东部春武里府和罗勇府橡胶木（巴西橡胶树）家具行业685名工人肺功能的影响因素。通过问卷调查、采集木尘样本和肺活量测定收集研究数据。工厂内木尘暴露的平均水平为4.08毫克/立方米（标准差=1.42，范围：1.15 - 11.17毫克/立方米）。预计用力肺活量（FVC）、一秒用力呼气容积（FEV1）和FEV1/FVC值的平均总体百分比分别为84%（标准差=13.41）、86%（标准差=14.40）和99%（标准差=10.42）。平均粉尘暴露水平与FVC（p = 0.0008）和FEV1/FVC%（p < 0.001）之间存在显著负相关，但与FEV1不存在显著负相关（p = 0.074）。木工肺功能下降与木尘水平之间的关联表明，橡胶木粉尘暴露对肺功能有负面影响。
