石棉是一种纤维状矿物,因具有耐酸、耐碱、耐火隔热、绝缘等性能而被广泛应用。然而,长期接触石棉粉尘可以引起石棉肺、肺癌及胸膜间皮瘤等疾病。生活环境中存在的石棉粉尘造成的污染,称为生活性石棉污染。其主要来源,除了石棉的开采,生产过程中可直接向环境扩散外,石棉制品的大量使用,是构成广泛而持久的环境污染的重要因素.例如,石棉建材的大量应用,不仅在建筑或维修过程中能引起一时性的环境污染,而且随时间的流逝,含石 Asbestos is a fibrous mineral that has been widely used due to its properties of acid resistance, alkali resistance, fire resistance, heat insulation and insulation. However, long-term exposure to asbestos dust can cause asbestosis, lung cancer and pleural mesothelioma and other diseases. The pollution caused by the asbestos dust in the living environment is called the life asbestos pollution. Its main source, in addition to asbestos mining, the production process can be directly spread to the environment, the extensive use of asbestos products, constitute a broad and lasting environmental pollution, an important factor.For example, the extensive use of asbestos building materials, not only in the construction or maintenance The process can cause temporary environmental pollution, and with the passage of time, containing stone
