Scanning electron microscopy of lung tissue, ashed at low temperature, and obtained from an insulation worker who had died of pleural mesothelioma, showed the presence of numerous inorganic particles and fibres. A regional variation in fibre concentration in different tissue samples was found, and the size distribution of naked fibres and asbestos bodies was determined. By energy dispersive x-ray microanalysis the fibres were identified mainly as amphibole asbestos. This method also showed the presence of particles containing titanium and of fragments of diatom shells. Despite a mean concentration of 33 x 10(6) fibres per gram of dry tissue no significant lung fibrosis was found.
对一名死于胸膜间皮瘤的绝缘工人的低温灰化肺组织进行扫描电子显微镜检查，发现存在大量无机颗粒和纤维。在不同组织样本中发现纤维浓度存在区域差异，并测定了裸纤维和石棉小体的大小分布。通过能量色散X射线微分析，纤维主要被鉴定为闪石石棉。该方法还显示存在含钛颗粒和硅藻壳碎片。尽管每克干组织中纤维的平均浓度为33×10⁶，但未发现明显的肺纤维化。
