1 changed in the last two years with regard to brakes? Page 53 2 A I wouldn't say they've changed with respect to 3 what I believe occurred between 1900 and 2000. I think 4 by definition state of the art means what is going on 5 up to the movement so I would say the information of 6 the last two years further convinces me that the 7 relationship, or lack of a relationship actually 8 between exposure as a mechanic and mesothelioma or lung 9 cancer, asbestosis, is just not there. 10 Q Am I correct that is primarily due to the dose 11 of asbestos that mechanics are exposed to? 12 A I wouldn't limit it to that. I think that 13 there are five or six factors that I've discussed 14 before. Langer has his own views about the five or six 15 that are very similar to mine. I'd say virtually 16 identical except he has stronger views that the break 17 wear debris, even the asbestos and break wear debris is 18 different. And he thinks it's not causal due to the 19 chemical change in the asbestos and the chrysotile. 20 I don't have a learned opinion about that but 21 that would be the only difference among the five 22 factors, that is, and I can go over those, it's 23 basically duration of exposure, concentration, the 24 fiber length of the fibers that are available, the fact 25 it's chrysotile, and, you know, of course, the ESQUIRE DEPOSITION SERVICES (415) 288-4280
