We report a prevalence study of environmental pleural plaques in subjects over 50 years old from the northeastern Corsican village of Murato, built on asbestos surface deposits. The percentage of plaques was 41%, versus 7.5% in the control village of Vezzani. Although surface deposits contain both chrysotile and tremolite, airborne pollution and asbestos lung burden of exposed inhabitants consist essentially of tremolite as assessed by transmission electron microscopy (TEM). However, TEM analysis of the parietal pleura of three animals bred in exposed areas showed a predominance of short fibers of chrysotile. The respective roles of tremolite and chrysotile in inducing pleural plaques in Corsica should thus be considered.
我们报告了一项针对来自科西嘉岛东北部穆拉托村50岁以上人群的环境性胸膜斑患病率研究，该村建于石棉地表沉积物之上。胸膜斑的比例为41%，而在对照村韦扎尼为7.5%。尽管地表沉积物中同时含有温石棉和透闪石，但通过透射电子显微镜（TEM）评估，暴露居民的空气传播污染和石棉肺负荷主要由透闪石组成。然而，对在暴露区域饲养的三只动物的壁层胸膜进行TEM分析显示，温石棉短纤维占主导。因此，应考虑透闪石和温石棉在科西嘉岛诱发胸膜斑中的各自作用。
