| 一些旧住宅的天花板、管路的绝热、隔间材料大多是石棉制品；一些建材、家装材料，例如：石棉水泥、乙烯基塑胶地板等，当这些石棉材料被拆修、切割、重塑时，会有大量的细小的石棉纤维飘散在空气中。 Some old houses' ceiling, pipeline insulation and compartment materials are mostly asbestos products; some building materials and home decoration materials, such as asbestos cement, vinyl plastic floor, etc., when these asbestos materials are disassembled, repaired, cut and reshaped, there will be a large number of small asbestos fibers floating in the air. 小石棉纤维飘散在空气中。石棉水泥管道用于输送水管时还会造成饮用水污染。石棉本身并无毒害，它的最大危害来自于它的纤维。这是一种非常细小，肉眼几乎看不见的纤维。这些细小的纤维被吸入人体内，就会附着并沉积在肺部、造成肺部疾病，如石棉肺，胸膜和腹膜的皮间瘤等；这些肺部疾病往往会有很长的潜伏期。因此，石棉已被国际癌症研究中心肯定为致癌物。 Small asbestos fibers are floating in the air. When asbestos cement pipes are used to transport water pipes, drinking water pollution will also be caused. Asbestos itself is not poisonous, its greatest harm comes from its fiber. It's a very small fiber that's almost invisible to the naked eye. When these tiny fibers are inhaled into the human body, they will adhere to and deposit in the lungs, causing lung diseases, such as asbestosis, pleural and peritoneal mesothelioma, etc.; these lung diseases often have a long incubation period. Therefore, asbestos has been identified as a carcinogen by the international cancer research center. |
