Asbestos is a commercial term that includes six regulated asbestiform silicate (silicon + oxygen) minerals. Because this group of silicate minerals can be readily separated into thin, strong fibers that are flexible, heat resistant, and chemically inert, asbestos minerals were once used in a wide variety of products
It is a hydrous magnesium silicate with the chemical composition of "Mg3Si2O5(OH)4"Mg3(Si2O5)(OH)4 - Chrysotile; Fe7Si8O22(OH)2 – Amosite; Na2Fe2+3Fe3+2Si8O22(OH)2 – Crocidolite; Ca2Mg5Si8O22(OH)2 – Tremolite asbestos; Ca2(Mg, Fe)5(Si8O22)(OH)2 – Actinolite asbestos; (Mg, Fe)7Si8O22(OH)2 – anthophyllite asbestos. The other types all belong to the amphibole group of minerals and include the fibrous forms of anthophyllite, amosite ("grunerite", crocidolite (riebeckite), tremolite, and actinolite. Though valued since ancient times for its resistance to fire, asbestos fibre did not achieve commercial importance until the 19th century. Modern asbestos production began in 1868 with the workings of a mine in Italy, and in 1878 large-scale production from deposits in Quebec began. Production slackened in the late 20th century owing to the health hazards posed by the mineral.
Reports of the harmful effects of asbestos fibres on human health caused increasing concern beginning in the 1970s, however. It was found that prolonged inhalation of some forms of the tiny fibres can result in a lung condition known as asbestosis or in mesothelioma, which is a rapidly fatal form of lung cancer. Once these health risks were firmly documented in the :1970s:, regulatory agencies in the United States and other developed nations began placing tight restrictions on workers’ exposure to asbestos in industrial plants. Crocidolite poses the greatest health hazard, whereas exposure to low levels of chrysotile is not a health hazard. In 1989 the U.S. government instituted a gradual ban on the manufacture, use, and export of most products made with asbestos. Since the 1980s various substitutes for asbestos have been developed for use in many products.
