- ‘Both amosite and crocidolite, which typically contains well over 20% iron by weight, are biochemically reactive in the lung because of the catalytic effects of ferrous iron present on the fibre surface.’
- ‘Asbestos, a fibrous hydrous silicate mineral, exists in 6 forms for industrial use: actinolite, amosite, anthophyllite, chrysotile, crocidolite, and tremolite.’
- ‘The major types of silicates causing asbestos-related disease are chrysotile, amosite, and crocidolite, with the latter being the most pathogenic.’
