X^eiid Xndkisiipies Aa&a-ciatioit i NEW YORK 17.N.Y. 60 EAST 42NO STREET MANFRED BOWDITCH I DIRECTOR OF HEALTH AND SAFETY September lli, 1956 Robert A. Kehoe, M. D. Director, Kettering Laboratoiy University of Cincinnati Eden Avenue Cincinnati 19, Ohio Dear Bob: Herewith is a copy of a letter just written to Mr. Elder of the A.P.H.A. I gather that, with Dr. Merrill's approval,the matter will be referred to the Occupational Health Section, and I hope very much that you will get behind it. / As to CaEDTA, I think there would be merit in writing it up as a supplement to the present book, as it would then be useful, separately, in the many cases when one wishes to refer only to that subject. MB: GW Enclosure an Public Health Asaoclation roadway :e up with Dr. Malcolm Merrill, Chairman of/yovsr Committee on Research and Standards, in two respects, one of which ia/ofvery >&1 impdr^snce. I refer primarily to the raienee of any reference to the "CaEDTA* treatment for lead poisoning, which has now o^n in use fdir/ same six years and has proved itself of outstanding value when administered by physicians having an understanding of its use* fulness and its limitations^ Th^possibilities of its misuse- are, however, such as to which a copy is herewith* To ^farther illustrate the spread of this problem, both chrono logically mad geogrtlp^ally^Gbplea of an earlier publication and two quite recent ones are also enclosed. Tfieea'are'but a few of what are now literally hundreds of published references to EDTA, copies of a number of which are available from this office on re quest. * The other of the two shortcomings referred to above is the lsck of any mention of the so-called coproporphyria test for lsad absorption. While a subject of far less im portance than is that of .EETA, its usefulness as a screening test under certain cir cumstances is such as to render its omission from a publication purporting to cover ths broad subject of industrial plumbtarn a rathar regrettable deficiency. If Z can be further helpful in ths above connection, I hope you will let as know* Sincerely yours. IfiiGW Baoloeruree cci Dr. Kehoe |te i 01377 N 24998.01
