In a routine survey of 623 miners in one colliery, 21 men, an unusually high number, showed radiological progression of simple pneumoconiosis in spite of generally low exposures to mixed coalmine dust. Comparison of the dust exposures of the 21 men with those of matched controls without pneumoconiosis showed highly significant differences in the proportion of quartz in the mixed dust to which they had been exposed. Quartz exposure may be an important factor in the development and rapid progression of coalworkers' pneumoconiosis. Some indication of the levels of quartz exposure which are likely to be hazardous is given.
在对某煤矿623名矿工进行的常规调查中，有21名男性尽管普遍接触混合煤矿粉尘的程度较低，但却出现了单纯尘肺的放射学进展，这一人数异常之高。将这21名男性的粉尘接触情况与配对的无尘肺对照者进行比较，结果显示他们所接触的混合粉尘中石英的比例存在高度显著差异。石英接触可能是煤工尘肺发生和快速进展的一个重要因素。文中给出了一些可能具有危险性的石英接触水平的指标。
