Contact网页About Asbestos. There are different forms of asbestos, broadly divided into the amphibole (actinolite, amosite, anthophyllite, crocidolite, and tremolite) and serpentine (chrysotile) groups. Chrysotile is the most used form of asbestos worldwide and the only one that is commercially mined today. All forms of asbestos are known to cause cancer

Contact网页2009年5月12日The incongruence of dissolution (Mg ≫ Si) is more pronounced for commercial chrysotile than chrysotile from Val Malenco, likely because, in the former sample, greater fragmentation and/or the occurrence of intergrown balangeroite fibres facilitate the access to the octahedral sheets; and (iii) balangeroite releases substantial
Contact网页2009年7月1日The results of solubilization assays on magnesium and silicon, as well as measurement of the Mg/Si ratio in the asbestos fibres after exposure to fungal mycelia, indicate a high bioweathering activity of V. leptobactrum towards chrysotile.
Contact网页Chrysotile fibres exhibit a range of physical characteristics. The fibre may be non-flexible ('stiff') and low in tensile strength ('brittle'), and may lack an ability to curl. This fibre, referred to as 'harsh', sheds water more quickly than its curly, flexible 'soft' variety. The behaviour of the harsh fibres is more amphibole-like and their

Contact网页2009年5月12日Chrysotile, the most abundant and widely employed asbestos, is often associated with minor amounts of tremolite, an amphibole asbestos. Both chrysotile and tremolite are widely recognized for their carcinogenicity ( International Agency for Research on Cancer, 1977; WHO, 1986 ).
Contact网页Asbestos fibres have a high aspect ratio, generally over 8. Based on their physical configuration they can be divided into two major groups, serpentine and amphibole. The physical dimensions and configuration of asbestos fibres are strongly linked to their pathogenicity. Chrysotile (white asbestos) is the only important serpentine form.
Contact网页Chrysotile fibres exhibit a range of physical characteristics. The fibre may be non-flexible ('stiff') and low in tensile strength ('brittle'), and may lack an ability to curl. This fibre, referred to as 'harsh', sheds water more quickly than its curly, flexible 'soft' variety. The behaviour of the harsh fibres is more amphibole-like and their
Contact网页No airborne fibres had a diameter greater than 3 micrometers, and all would therefore be capable of reaching the pulmonary alveoli. It was shown that for the same airborne mss of the different varieties of asbestos, fewer amosite fibres would be present than crocidolite or chrysotile fibres.
