In the late 1990s and early 2000s, the Government of Canada continued to claim that chrysotile was much less dangerous than other types of asbestos. [28] Chrysotile continued to be used in new construction across Canada, in ways that are very similar to those for which chrysotile was exported. [29]
North-west of Nelson, in the Upper Takaka Valley is New Zealand's only commercially harvested asbestos mine. A low-grade Chrysotile was mined here from 1908 to 1917 but only 100 tons was washed and taken out by packhorse. A new power scheme enabled work to renew and between 1940 and 1949, 40 tons a month was mined by the Hume Company.
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
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.
Red Dye number 3 has been banned by the FDA due to its potential link to cancer in animals, but it is not a significant health threat to humans.
In contrast, lizardite and chrysotile typically form near the Earth's surface and break down at relatively low temperatures, probably well below 400 °C (800 °F). It has been suggested that chrysotile is never stable relative to either of the other two serpentine polymorphs.
