Chrysotile, tremolite and carcinogenicity [PDF]
The Annals of Occupational Hygiene, 1997 It has been suspected for many years that amphibole fibres in the tremolite series, a low level contaminant of chrysotile asbestos, may contribute disproportionately to the incidence of mesothelioma and perhaps other exposure-related cancers. A cohort of some 11,000 Quebec chrysotile workers, 80% of whom have now died, provided the opportunity to ...

Biological effects of tremolite [PDF]
British Journal of Cancer, 1982 Tremolite is an amphibole which has been implicated in a variety of disease patterns in different parts of the world. It occurs in a number of phases, which are chemically identical but have specific physical characteristics. In an attempt to clarify the epidemiological findings, tremolite fibres of 3 specific forms--A, B and C--were characterized and ...

Chrysotile, tremolite and fibrogenicity [PDF]
The Annals of Occupational Hygiene, 1999 Abstract 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. An analysis has therefore been made of radiographic changes in men who in 1965 were employed by companies in Thetford Mines ...
