\ April 1w Dr. John W. Sloan The Texas Company P. O. Box 712 Port Arthur, Texas Dear Doctor Sloan: I send you herewith the report of the analyses of the urine and blood of I am somewhat concerned about this man's apparent belief that he was subjected to exposure.to tetraethyl lead. If he was so situated that he had an opportunity for such exposure, he must have been working in the mixing plant, in a laboratory where TDD is handled, or in eLearning a gasoline storage tank. If, ou the other hand, he was exposed to gasoline vapors under the ordinary circumstances of handling gasoline, he must believe that exposure to these vapors involves a. significant degree of exposure to tetraethyl lead. I dislike putting you to extra trouble, but I would be grateful to ywu if you would lot me know just what were the circumstances that led him to think that he had been exposed to TDD. hly request is based in part on my wish to have the record straight in this case, and partly to enable us to know in what category to file the case. We keep fairly comprehensive recor.m of all complaints and incidents in relation to TED and Leaded gasoline. In any case, it is evident that no significant exposure to TED occurred. He may be assured of this fact, since, while the evidence would not show up in the blood {lead absorbed as TED does not give rise to much elevation of the blood lead), it would be readily apparent in iue urine. Cordially yours, RAK e Dictated but not read. Snc. Robert A. Kelioa, Id. D.
