Products with Potentiality for the Presence of Dioxins Considerable anxiety was expressed about the possibility that a "witch hunt" would be instituted about the presence of dioxins in products, leading to the banning of products that are in fact entirely safe.

The capital required and the manufacturing costs, at this stage of the game, and with our present knowledge do not lead us to believe that we will ever have a family tree as profitable as Aroclor.

This period began when Meriwether the Chief Inspector of Factories in the U.K. published his annual report with the finding that cancer of the lung or pleura occurred in 13 of individuals found to have asbestosis at autopsy This compared with a risk of 1.3 % in individuals with silicosis Also in 1949 an editorial in the Journal of the American Medical Association accepted the association between asbestosis and lung cancer As you undoubtedly know the JAMA is the most widely read journal among medical practitioners in this country In 1951 Gloyne found 14 of individuals with asbestosis had pulmonary cancer in an autopsy series confirming the findings of Meriwether Also around this time attention was directed to an increase in the female to male ratio for lung cancer in individ- uals with asbestosis as compared to the general population again supporting an occupational association In 1953 Harriet Hardy and colleagues published two case reports in the American Journal of Medicine with the conclusion that the causal association is highly likely I mention this because the American Journal of Medicine has been widely read by physicians specializing in internal medicine It is also of some interest but perhaps not entirely relevant to the present discussion that in 1953 and 1954 the suggestion was made that pleural and peritoneal mesotheliomas respectively were associated with asbestos exposure these reports appearing in the German literature During this time period I would conclude that the medical literature might lead the reader to the opinion that the association between asbestosis and lung cancer was now probable Finally the last time period is 1955 until the present This phase of course began with the publication by Richard Doll using the most valid epidemiologic techniques up to that time to investigate a causal association i.e. a specific mortality study of workers with defined employment in a specific plant He found that employees of this asbestos textile factory had approximately ten times the risk of developing lung cancer than members of the general population He suggested that this risk was confined to those individuals who also had asbestosis Also in 1955 editorials in the British Medical Journal Lancet and American Journal of Clinical Pathology accepted this association as did the author of the most prestigious book on occupational medicine Donald Hunter It would be my judgment that since 1955 the causal association can be considered proven or definite Up to the present time there continues to be some difference of opinion concerning the question of whether the lung cancer risk is limited to individuals with asbestosis or is present in those only with asbestos exposure The primary reason for this uncertainty is because the definition of asbestosis is highly variable and on one extreme might be based on thor ough histologic examination with the whole lung available and on the other might depend on several clinical radiographic and physiologic criteria My judgment at present is that it is probable that the level of asbestos exposure necessary to result in a detectable excess risk for developing lung cancer is also a dose which is likely to produce diffuse changes of pulmonary fibrosis asbestosis However the evidence of asbestosis may not be clinically or radiographically apparent I hope this discussion is useful You will of course appreciate that the time periods indicated above are arbitrary I would be most pleased to discuss any of these opinions with you or to provide clarification where required With kindest regards Sincerely yours HW cc Mr.

Once adopted the proposed regulations UEU-148542 will undoubtedly lead to a flurry of regulatory activity, the focus of which will probably be NIOSH's list of suspect carcinogens, numbering in excess of 2400.
