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 ...
The most common asbestiform mineral is chrysotile, commonly called "white asbestos", a magnesium phyllosilicate part of the serpentine group. Other asbestiform minerals include riebeckite, an amphibole whose fibrous form is known as crocidolite or "blue asbestos", and brown asbestos, a cummingtonite-grunerite solid solution series.
Diopside is a precursor of chrysotile (white asbestos) by hydrothermal alteration and magmatic differentiation; [6] it can react with hydrous solutions of magnesium and chlorine to yield chrysotile by heating at 600 °C for three days. [7]
[4] [5] Health problems attributed to asbestos include asbestosis, mesothelioma, lung cancer, and diffuse pleural thickening. [6] [7] One of the major issues relating to asbestos in civil proceedings is the latency of asbestos-related diseases. Most countries have limitation periods to bar actions that are taken long after the cause of action ...
