同个，岩棉、玻镁(mei)亦会造成(cheng)肝癌、肋膜间皮瘤及肋膜良好病(bing)痛(tong)。得(de)岩棉、玻镁(mei)沉著病(bing)的(??de)人前中期(qi)才可以即便潜在(zai)肺炎及因肺脏单一化纤维材料化潜在(zai)肺原性(xing)心室(shi)病(b??ing)，造成(cheng)心室(shi)衰退而灭亡。
石(shi)英砂的(de)粉尘极细，比外表积到达100m2/g以上??能够或许(xu)悬浮(fu)在氛围中，若是(shi)人持久吸入含有石(shi)英砂的(de)粉尘，就会患(huan)硅肺(fei)病（因硅旧(jiu)称为(wei)矽(xi)，硅肺(fei)旧(jiu)称为(wei)矽(xi)肺(fei)）。
