July 5, 19^3 (1 9 ) Dr . T . P . Hickey, E . I . du Pont Company, Joliet, Illinois. !, Dean D r . Hickey: - In confirmation of ray wire of yesterdag^^am sending you the report on the urine and blood o I should also amplify the interpretation in the telegram by a few additional comments. We have seen cases of lead Intoxication in individuals with lead concentrations in the blood of the order of magnitude shown here- Generally speaking, hovever, such concentrations were found not during the peak of the absorption, but at a later date after the subject had been removed from exposure and after the symptoms had subsided hut not completely vanished. Therefore, it is not safe to say that the symptoms in this case might not be due in part or in vhole to lend absorption. It would be quite fair, however, to say that the symptoms in such a case should be mild and rather fleeting. Hone of the more severe consequences of lead absorption would be expected to be present, unless they had developed at a prior time while the exposure was heavier, that is, before the cessation of exposure, (i insert this reservation only for the reason that it is not quite clear from your history whether this man worked right up to the present time, or whether his exposure had occurred and come to an end some weeks before these samples were collected . Actually, in making an interpretation of such data as these, one should have all of the precise information concerning the nature of the work, the time at which exposure occurred, whether inter mittent or continuing, and the date on which the last exposure occurred. Without such information one is compelled to be some what discursive, as I am here.) As to the urine, the result is only slightly above normal levels. Taken in conjunction with the blood finding with which it is in satisfactory agreement, I should conclude that this man's expo sure had only been slight. It is not uncommon to find analytical results of this type among rather large groups of persons among whom no cases of lead poisoning have been seen. In my opinion, It is most unlikely that this man's symptoms are due to his lead N 7244 Dr. T. P. Hickey - (2) - July 3, 19^3 exposure. ' Cordially yours, EAK er t.nc . Robert' A . Eehoe, M. D.
