Dust exposure and mortality in an American factory using chrysotile,
amosite and crocidolite in mainly textile manufacture.
It is a combination of amphiboles including winchite, richterite, tremolite, and
amosite and is very likely similar to the material to which the miners and townspeople were exposed over decades of mining the asbestos-contaminated vermiculite [31].
The serpentine chrysotile fiber is more readily removed by alveolar macrophages compared with the amphibole
amosite and crocidolite varieties.
Amosite would account for approximately 9% and the remaining 90% is chrysotile." Asbestos is deemed safe as long as it is undisturbed.
Energetic Dancing at seven, Dancing Welcome may be only the joint oldest in the field with
amosite but has certainly been the busiest.
Signed by former Health Minister Suleiman Franjieh and former Environment Minister Akram Chehayeb, the law bars the importing of Crocidolite,
Amosite, Anthophyllite, Actinolite and Tremolite but allows a common asbestos called Crysotile, known as white asbestos.
He instructed contractors to remove sprayed coating containing
amosite (brown asbestos) from steel beams while refurbishing the nightclub.
A second asbestos group known as the amphiboles includes crocidolite (blue asbestos) and
amosite (brown asbestos).
Amphibole fibers (crocidolite, tremolite, anthrophylite and
amosite) are mainly used as fire resistant application.
Barry Castleman, an expert on the history of asbestos, "asbestos industry, doctors and industrial hygienists came to serve increasingly as salesmen for the industry as it came under fire, trying to persuade customers that the scientific evidence wasn't so frightening." The main tactic of the CI was to suggest that chrysotile white asbestos was different in this respect from crocidilite ("blue asbestos") and
amosite ("brown asbestos").
(4) The principal varieties of asbestos are chrysotile, a serpentine mineral, and crocidolite,
amosite, anthophyllite, tremolite, and actinolite, all of which are amphiboles.
(36.) Section 4 of the Asbestos Information Act of 1988 defines asbestos as chrysotile,
amosite, or crocidolite, or in fibrous form, tremolite, anthophyllite, or actinolite.
