选择某卷烟厂2007年至2012年接触烟草尘的作业工人351人,对其X线胸片进行了为期6年的动态观察,分析X线胸片表现与接尘浓度和接尘时间的关系。本次调查的工作场所空气中总粉尘浓度范围0.26～4.9 mg/m3。X线胸片显示,接尘组检出双肺纹理增多,紊乱55人,其中13人合并肺结核,未检出烟草尘肺。提示长期低浓度的烟草粉尘暴露,可以引起接尘工人的肺部损害,表现为肺纹理的改变。同时,增加肺结核的患病风险。 Select a cigarette factory from 2007 to 2012 contact with tobacco dust 351 workers, their X-ray was a 6-year dynamic observation of the relationship between the performance of X-ray and dust concentration and dust collection time. The total airborne dust concentration in the survey ranged from 0.26 to 4.9 mg / m3. X-ray showed that dust detection group detected double lung texture, disorder 55 people, of whom 13 were complicated by tuberculosis, tobacco pneumoconiosis was not detected. Prompted long-term low concentrations of tobacco dust exposure, can cause dust damage workers lung damage, manifested as changes in lung texture. At the same time, increase the risk of tuberculosis.
