ShaDD Grenville < oo. i This is in further reference to the subject paper in which a statistical study was made of the health history of 632 insulation workers who had been exposed to asbestos dust for a period of 20 years and longer During the period of 1943 to 1962 Selikoff reports that 45 of the 632 workers died of cancer of the lung pleurs and trachea whereas only 6.5 4 such deaths would be expected from general U.S. experience He goes on to state Thus it was found that the death rate from cancer of the bron and pleure was 6.8 times as high as in the general U.S. white male population underlining mine in It is this comparisco that I feel is not scientifically sound Rather than making a comparison with the general U.S. experience a comparison should have been made with white males who had lived in the same metropolitan New York City area for comparable periods This is not to infer that no difference in death rate from cancer would been found between the asbestos workers and the white males in New York but it is well known that the incidence of his cancer is such greater our larger cities than in small toms and rural anu have City in WCTI WCTI 246
