Welsh/K. S. Lane oh September 5 1972 Oricmotinj D*pt Medical Department Answering Uffar Joft CONFIDENTIAL Dear Bill: At this time we do not regard the use of a gravimetric system for evaluation of asbestos with much favor. We have tried it briefly at King City in comparison with the count system but found no correlation between the two. Our tests were limited, of course, because we did not have time for exploration of the system in depth; nevertheless, I feel the conclusions were valid. As a second point, I strongly question the use of typical mixtures (asbestos) as reasonably applicable to all the many uses of asbestos. Forrour products, in particular, the potential error in the "typical" approach is very great. Finally, the possibility of error in determining weights of small quan tities of particulates as would be obtained in the use of personal air sam plers is very high. Nothing less than extreme care in physical handling of the samples, in drying, and in control of inherent potential balance errors such as those that reflect temperature variations, static electricity, vibra tion, etc. would be acceptable; and even with this effort, I wouldn't be at all surprised to have some samples reflect weights completely at odds with the visible conditions. Eesults, therefore, would he rightly open to question. SEP 7 . EXHIBIT I UC-1517 2- - As you are aware, we are not very hrppy with the present system of fiber evaluation and, consequently, we are still searching for something better. Unfortunately, the weight procedure offers no improvement so far. Yours very truly, FWM:mc ... Paul W. McDaniel Industrial Hygiene Engineer Q'Vip UinT White & Yellow Copi toVSup^\^lQrV.

This follows from the uncontrollable variables inherent in the industrial situation and other factors which have been discussed. For these reasons, it appears Improbable that any research agency would consider it advisable to under take such a project except under special conditions already discussed, and which may not be attainable. (5) The. McIntyre Research Foundation, as presently organized, is not equipped to solve the aluminum prophylaxis problem in relation to silicosis. The steps considered necessary to accom plish this objective are outlined. (6) Research should be continued with laboratory animals with the object of finding a more adequate ba3i3 for application to man. Such study is now included in the program of the Saranac Laboratory of the Trudeau Foundation. -- Authors' Summary 66 Effects of Electricity on the Human Body. W.B. Kouvenhoven. Ind. Med. 16, 2t>9 (July, 1949). The author discusses briefly the various effects of electricity on the body, including variations with the amount of current. The current values of interest are: (1) threshold of feeling, about 1 milliampere; (2) let-go current, above which it is difficult to let go of a wire, about 9 milliamperes for men, 6 for women; (5) current producing ventri cular fibrillation, 0.1 ampere; (4) current producing a block in the ner vous system, one ampere or more; and (5) the counter shock current. The last three result in death if prolonged; otherwise artificial respiration may nave the victim. These effects refer to alternating current of com mercial frequency. Direct current 13 much less harmful. The only effect of high-frequency currents is heating. ' 67 Asbestosis and Cancer of the Lung. Editorial. J.A.K-A. 140, 1219-1220 (Aug. 15, 19^97- Records of English, American and German physicians and The Annual Report of the Chief Inspector of Factories in England for 1947 show that the occurrence of cancer of the lung is related to pulmonary asbestosis. This relation is supported by the following observations: (l) The incidence rate of cancer of the lungs in asbestosis patients is 10 to 15 times as high as among the general population.(2) The male-female ratio is more nearly equal than it in for the gen.-ral populs.il Ion, vhlrh inili enter.
