The amount of industrial wastes with asbestos such as dismantled construction materials has increased. We have reviewed the effect of asbestos-containing products subjected to harmless treatment on the lungs. Usually, the harmless treatment of asbestos is confirmed by the disappearance of fibrous materials and crystal structures by electron microscopy and X-ray diffraction. However, it is very important to perform animal studies and in vitro studies in order to examine the effect of the treated asbestos-containing products on the lungs. From previous treatments of asbestos using acids or high temperature, almost treated materials tended to show decreased toxicity in vitro and in vivo studies. There are some reports of the adverse effects of the treatment. If new harmless treatments of asbestos are developed, it is necessary to perform animal studies and in vitro studies of asbestos-containing products using new harmless treatments.
含有石棉的工业废料数量有所增加，比如拆除的建筑材料。我们回顾了经过无害化处理的含石棉产品对肺部的影响。通常，石棉的无害化处理通过电子显微镜和X射线衍射观察纤维材料和晶体结构的消失来确认。然而，为了研究经过处理的含石棉产品对肺部的影响，进行动物研究和体外研究非常重要。从以往使用酸或高温处理石棉的情况来看，几乎所有经过处理的材料在体外和体内研究中都显示出毒性降低。也有一些关于这些处理产生不良影响的报道。如果开发出新的石棉无害化处理方法，有必要对使用新无害化处理方法的含石棉产品进行动物研究和体外研究。
