In a sample of 186 stone workers who performed granite "tearing" and "stone work" (either manual or mechanical) we have found silicosis in 50.5% (simple silicosis 47.3%, and complicated silicosis 3.2%). The most commonly found radiologic manifestation was a round opacity type "p" and a 1/1 to 1/3 profusion. From a functional respiratory perspective, a mild reduction of FVC, DLco (SB) and pO2 similar to that described in coal miners' pneumoconiosis was observed. It seems that "stone workers" had a higher incidence of suffering severe silicosis than stone "tearing" workers. Surprisingly, in the analysis of inhaled dust of such an activity which is performed in the open air the rates of dust and SiO2 are much higher than those found in coal workers. We believe that this is the first time that these measurements are performed, and published, in a group of stone workers.
在186名从事花岗岩“开采”和“石材加工”（手动或机械）的石匠样本中，我们发现矽肺病患病率为50.5%（单纯矽肺病47.3%，复杂矽肺病3.2%）。最常见的放射学表现是“p”型圆形阴影和1/1至1/3的密集度。从呼吸功能角度来看，观察到用力肺活量（FVC）、肺一氧化碳弥散量（DLco，单次呼吸法）和氧分压（pO2）出现轻度下降，这与煤矿工人尘肺病的情况类似。似乎“石材加工工人”患重度矽肺病的发生率高于石材“开采”工人。令人惊讶的是，在对这种露天作业吸入粉尘的分析中，粉尘和二氧化硅的含量远高于煤矿工人。我们认为，这是首次在一组石匠中进行并公布这些测量数据。
