Abstract: Asbestos minerals are thin fiber type of minerals and honorably said as “the minerals of the miracle” because of their valuable natures even in the strategic field. On the other hand, the relation between asbestos exposure and diseases such as lung cancer and malignant mesothelioma was proved around 1970 by epidemiology and an animal experiment in relation to their microstructures. Here, microstructures of chrysotile asbestos, a mainstream of asbestos substances, are shown. It is also shown that in what kinds of environment people are exposed to asbestos and what kinds of biological or epidemical things happen after asbestos exposure. Many kinds of fibrous materials as the substitutes of asbestos are described in relation to their carcinogenicity.

Keywords: Structure of asbestos, biological influence of asbestos exposure, asbestos substitutes
