Department of Preventive Medicine and Industriai Health The lettering Laboratory Eden Avenue Cincinnati 19, Ohio Dear Dr, Kehoe: Your letter to Mr, Jack Hershcopf and series of articles sent under separate cover have been received,- Mr. Hershcopf is out of the country at the present time and Is not expected to return until approximately June 1st, I will bring your letter and articles to his attention as soon as he returns as I know he will be anxious to read same. In the meantime I wish to express Mr, Hershcopf1s appreciation. Respectfully yours, Secretary to Mr. Hershcopf N 6025 HU DR A llLlC April 16, 1955 Mr* Jack Kershcopf A.M.A. Corporation P. 0. Box 65 Rockville Center, Hew York ' Dear Mr * Kershcopf: In accordance with your letter of April 7, I am sending you under Separate cover a series of articles that have to do with the problems in which you are interested. Undoubtedly the most important of these is the green booklet, the report of the ICommittee on Lead Poisoning of the industrial Hygiene Section of the American Public Health Association, of which. I had the honor to be chairman. At the time this work was performed, the members of our committee agreed to assemble together within two covers, the most practical form of - information which we could supply, and which would be quite ot3ide th field of disagreement of the various people who made up the membership of the committee. I think that this is the most useful bit of information in print on the subject of how to go about the control of occupational exposure to lead. May I say that the problem of dealing adequately with hazardous exposure to lead is relatively simple once one understands what is trying to, achieve* The simplicity resides in the fact that the only means of achieving the desired result is the proper control of conditions of exposure. This can be done in such a way as to prevent any and all cases of lead poisoning. The only question is how much money one is pre pared to spend to institute the proper control. The role of the physician in this is substantially to determine whether the precautionary measures are sufficient. There is little that he can do,other than to remove men from hazardous exposure to prevent lead poisoning, if the occupational conditions are actually hazardous. The control of hazard, therefore, is a mechanical and engineering job. On the other hand, the recognition of dangerous exposure, whether in the group of exposed personnel, or in the individual case, is the function of the doctor, and this can be done with the degree of preci sion which will make it possible to avoid any and all diffi culties . The real problem here is the acquisition of a sound understanding of the methods by those who are responsible for the engineering, on the one hand, and the medical obser vations, on the other* It occurs to me that your medical representative might wish to spend a day or two with us and to apprise himself of the methods that can be employed in dealing with this problem. We have enjoyed the privilege, Mr. Jack Hershcopf - (2} - April 16, 1953 from time to time, of aiding in the setting up of a medical regimen that would he satisfactory in this regard, and we should he pleased to he of any assistance that is possible in this connection. If he should care to communicate with me directly, raising any questions that he may choose, or-if he should wish to pay us a visit, we should he glad to do what we can for him. - You and he may he interested in knowing that we are carrying out prolonged and elaborate investigation cf the problem of inhalation of lead, using experimental human-subjects under laboratory conditions. Our purpose, in these experiments, is to follow up on our elaborate studies of the results of the Ingestion of lead by-human beings, so as to clarify the entire picture of the respiratory absorption of lead and the fate of such absorbed lead in the human organism. The problems at issue here,are the influence of the chemical compound Itself, on the outcome, the influence of particle size, mid the influence of dose. A considerable amount of time will taken to explore these matters, but we expect to have the answer within a finite period of time. Cordially your3, Robert A. Kehoe , M7"T>7 RAK ef : .

Corporation P . 0 . Box 6 5 Rockville Center, New York .. Dear Mr. Hershcopf: Although your note requesting a copy of a paper on industrial lead poisoning does not identify the occasion, I presume that you refer to a ,taik which 1 gave recently on the medical control of lead poisoning in industry at the University of Pennsylvania. Unfortunately this talk as usual was made from notes and not from a prepared manuscript. A rather large series of articles on lead poisoning have been published by us over the years, and our investigative work and experience, while not published up to.date, are already available in medical litera ture. Insofar as reprints of these are now available, I should be glad to send you such as may be of interest., if you will let me know wherein your interest lies. Our supply of some of the earlier publications has been exhausted, but I can give you references to them. Very truly yours, RAK ef Robert A. Kehoe, M.
