Amosite and crocidolite are considered the most hazardous asbestos fiber types; [5] however, chrysotile asbestos has also produced tumors in animals and is a recognized cause of asbestosis and malignant mesothelioma in humans, [6] and mesothelioma has been observed in people who were occupationally exposed to chrysotile, family members of the ...
Three polytypes of chrysotile are known. [8] These are very difficult to distinguish in hand specimens, and polarized light microscopy [6] must normally be used. Some older publications refer to chrysotile as a group of minerals—the three polytypes listed below, and sometimes pecoraite as well—but the 2006 recommendations of the International Mineralogical Association prefer to treat it as ...
Pleural contamination with asbestos or other mineral fibers has been shown to cause cancer. Long thin asbestos fibers (blue asbestos, amphibole fibers) are more potent carcinogens than "feathery fibers" (chrysotile or white asbestos fibers). [28] However, there is now evidence that smaller particles may be more dangerous than the larger fibers.
Chrysotile, a form of asbestos, is a proven human carcinogen (List of IARC Group 1 carcinogens). It is known contributor to mesothelioma. However, unlike other asbestos forms of asbestos such as crocidolite and amosite, Chrysotile only poses a risk when absorbed in extreme quantities. This is due to the fact that Chrysotile is a rolled ...

When Melissa Lamesch is found dead at home in Mt. Morris, Illinois, on the day before Thanksgiving, authorities zero in on Matthew Plote, a man trained to save lives, not take them.
Serpentines find use in industry for several purposes, such as railway ballasts, building materials, and the asbestiform types find use as thermal and electrical insulation (chrysotile asbestos). The asbestos content can be released into the air when serpentine is excavated and if it is used as a road surface, forming a long-term health hazard ...
