In some villages in central Turkey pleural changes occur as a result of environmental exposure to mineral fibres. In most cases the fibre is asbestos but in some cases the non-asbestos fibre erionite, a zeolite, is responsible. The incidence of malignant mesothelioma is much higher in "erionite villages" than in "asbestos villages" despite similar frequencies of pleural changes. In this study chest radiographs from 466 people from asbestos villages, 549 from erionite villages, and 382 controls were compared. The frequency of pleural calcification was about the same in the two groups of villages studied, but the minor fissures were visible to a greater degree in erionite cases. In people from erionite villages "atypical" pleural calcification, due to calcification of the visceral rather than the parietal pleura, was more common. These differences may indicate that the fibres have different lengths and diameters.
在土耳其中部的一些村庄，由于环境暴露于矿物纤维，会出现胸膜变化。在大多数情况下，纤维是石棉，但在某些情况下，非石棉纤维毛沸石（一种沸石）是致病原因。尽管胸膜变化的频率相似，但“毛沸石村”的恶性间皮瘤发病率远高于“石棉村”。在本研究中，对来自石棉村的466人、毛沸石村的549人以及382名对照者的胸部X光片进行了比较。在所研究的两组村庄中，胸膜钙化的频率大致相同，但在毛沸石病例中，小裂隙更易见。在来自毛沸石村的人群中，由于脏层而非壁层胸膜钙化导致的“非典型”胸膜钙化更为常见。这些差异可能表明纤维的长度和直径不同。
