Lung content analysis of cases occupationally exposed to chrysotile asbestos. [PDF]
, 1994 The lung contents of six workers who had been occupationally exposed to chrysotile asbestos were examined. Five were lung cancer cases from Quebec, Canada. The sixth, an American worker who had developed pleural mesothelioma, was particularly interesting,
