October 3 s 19:^2 Ensign Roland 1. l^rd, 1855 Schiller Street, Little Rock, Arkansas Roar Ensign. Byrd! In. accordance with your; request, X am sending' you suck inform mation as would sees to serve the purpose of the request in your-letter of September 26. . I hope It will be helpful. More over * if you can and care to give me some detailed information concerning . the nature of the lead exposure in which you are 'interested, I should be glad to give you my best advice with respect to what say be expected* If there is any regular expo sure to finely divided lead dusts in the concentration indicated in your letter, it would seem that eases of lead poisoning are very likely to occur, and without very mush delay. However, this depends to some degree on the nature of the compound, the size of the particles, and the conditions of exposure, expecially with reference to consistence or intermitteacy of expo sure . I think you can expect that any poisoning which occurs will be of relatively acute character* The expression 'chronic lead poisoning" is poorly based in fact* Generally speaking, unless men have long been exposed to comparatively high concentrations of lead without precautions and without medical care, so called ''chronic lead poisoning" does not occur. I assume, perhaps without foundation, that this is a fairly new type of exposure or at least that the men employed have, not been engaged in work of this type over a long period of time. / Very truly, yours.,, RAE ef Robert A.
