摘要

Recently published analyses have shown that the risks of mesothelioma and lung cancer in Quebec chrysotile miners and millers were related to estimated level of fibrous tremolite in the Mines where they had worked.

Of 294 men who met the necessary requirements, 129 had Worked in six centrally located mines, where the tremolite content was thought to be high, 81 in 10 peripheral mines where it was thought to be low and 84 in both.
