高浓度粉尘引起尘肺早被公认,而低浓度粉尘,特别是在接近容许浓度或容许浓度以下长期生产的工人,是否可以发生尘肺,目前还是没有解决的问题。为此,我们对本钢耐火材料厂低浓度粘土粉尘岗位的制砖工人进行了动态观察。
Pneumoconiosis caused by high concentrations of dust has long been recognized as a problem that remains unclear whether low concentrations of dust, especially those exposed to long-term production below allowable concentrations or allowable concentrations, can develop pneumoconiosis. To this end, we made a dynamic observation of the bricklayer at the low-concentration clay dust station in the Bengang refractory plant.
