Emphasis was placed on the importance of assessing the differences in organic content ofasbestos to which workers were exposed, but in toe end there was no evidence that organic contaminants accounted for increased cancer rates. In 1969, Wagner and Berry published a report in toe British Journal ofCancer demonstrating that removal of organic contaminants from asbestos did not decrease, and in fact possibly increased * toe ability of toe fiber to cause mesotheliomas in rats.(Wagner and Berry 1969) Therefore toe argument that oil contaminants were toe chief cause oftoe carcinogenic effects of chrysotile exposure was no longer plausible, and had to be scrapped in exchange for more otter explanations as to why chrysotile was safe. 6
