MESOTHELIOMA IN QUEBEC CHRYSOTILE MINERS AND MILLERS: EPIDEMIOLOGY AND AETIOLOGY

摘要

In a cohort of some 11000 men born 1891-1920 and employed in the Quebec chrysotile production industry, including a small asbestos products factory, of 9780 men who survived into 1936, 8009 are known to have died before 1993, 38 probably from mesothelioma-33 in miners and millers and five in factory workers. Among the 5041 miners and millers at The ford Mines, there had been 4125 deaths from all causes, including 25 (0.61/100) from mesothelioma, a rate of 33.7 per 100 000 subject-years; the corresponding figures for the 4031 men at Asbestos were eight out of 3331 (0.24/100, or 13.2 per 100 000 subject-years).
