[Trevor Ogden] agreed to serve on the panel despite warnings from groups opposed to Canada's trade in asbestos because he supported Health Canada's decision to "do a good thing" by considering the science behind the cancer-causing potential of chrysotile. "Clearly it's been overtaken by other interests," he says.The resulting panel discussions led to at least one "harsh" exchange between [David Bernstein] and Bice Fubini, a chemistry professor at the University of Turin in Italy. The disagreement concerned the chemistry of the chrysotile fibres and how long Bernstein claims they remain in the lungs if inhaled, Fubini told CMAJ. "Certainly I did disagree with the description he gave of the whole chemistry of the fibres."Until the early 1970s, Quigley sold products containing asbestos. Martin and other claimants have filed more than 171 000 lawsuits against Quigley alleging that exposure to asbestos made them ill. Pfizer Inc. bought Quigley in 1968. Martin's lawyer contended that Bernstein received US$400 623.20 from Union Carbide. During the trial, Bernstein testified that unlike amphibole asbestos, "the shorter chrysotile fibers are removed from the lung and they are not available to cause disease."
