There are three commercial types, listed in the order of most deadly, crocidolite, amosite and chrysotile
Since 2004 the Russian Federation, on behalf of its asbestos industry and with the assistance of Kazakhstan, Canada and a handful of other countries, has fought to prevent chrysotile
(one of the main minerals containing asbestos; also known as white asbestos) from being listed in Annex III of the Rotterdam Convention.
A single form of serpentine asbestos, called, chrysotile
or white asbestos, is the most commonly used form of asbestos, and accounts for approximately 95% of the asbestos found in buildings throughout the United States.

, or white asbestos, in Quebec dwindling, Canada's exports have ebbed, according to a report in the journal Lancet .
Yarborough concluded in his review that the role of chrysotile
fibers in mesothelioma pathogenesis is weak although he suggested the possibility of a threshold for chrysotile
For the past 15 years, Chadha has been buying chrysotile
asbestos from the Jeffrey Mine in Asbestos, Quebec (170 kilometres east of Montreal), selling it to about a dozen major cement manufacturers in India, where demand for the fibre is high.
asbestos in rocks is relatively harmless, they say, and unless someone were to work in a quarry for many years, the threat from serpentine is essentially zero.
