Explore: Amosite

Emmanuel-Louis Gruner (1809–1883), the Swiss-French chemist who first analysed it. Amosite is a rare asbestiform variety of grunerite that was mined as asbestos predominantly

needle-like. Amosite, crocidolite, tremolite, anthophyllite and actinolite are members of the amphibole class. Amphiboles including amosite (brown asbestos)

example, NA 2212 is all asbestos with UN 2212 limited to asbestos, amphibole amosite, tremolite, actinolite, anthophyllite, or crocidolite. Another exception

cummingtonite has lower ferric iron and aluminium than anthophyllite. Amosite is a rare asbestiform variety of grunerite that was mined as asbestos only

production ended in 1980. AIB is 16-35% asbestos, typically a blend of amosite and chrysotile, though crocidolite was also used in early boards. AIB is

chrysotile of the serpentine class and those belonging to the amphibole class: amosite, crocidolite, tremolite, anthophyllite and actinolite. Short, fiber-like

installed fibrous, loose-fill amphibole asbestos, in most cases brown amosite from South Africa, although blue crocidolite has been detected. It was

actinolite/tremolite series. The cummingtonite/grunerite series is often termed amosite or "brown asbestos", and riebeckite is known as crocidolite or "blue asbestos"

biopersistence of synthetic fibers after one year was 0.04–13%, but 27% for amosite asbestos. Fibers that persisted longer were found to be more carcinogenic

fibres. In the United Kingdom, the use of blue (crocidolite) and brown (amosite) asbestos was banned in 1985, while the use of white (chrysotile) asbestos
