COP Y QCCIJPATIONAL HEALTH LABORATORIES 211 Uilby St. Houston 3, Texaa Phone CApitol 7-5708 James H. Sterner, M.D., Medical Director Eastman Kodak Company 3L3 State Street ....... .... Rochester, New York . Dear S ir t . . November 9 1955 .. . Let me assure you that I do not recommend the prophylactic use of EDTA. do not consider it a panacea for the Ind ustrial Lead problem* I am acquainted with the feelings of CT8. Kehoe, Johnstone, Sterner, Shipman and Foreman in this matter and am also aware of recent work done at the Los Alamos Scientific Laboratory which casta doubt on the nontoxicity of EDTA. OHL reoommendS - "Install adequate exhaust ventilation at those positions where the workers show abnormally high lead values in w i n e or where the max imum allowable concentration in the air la constantly ex ceeded." OHL suggests treatment of workers with high ur inary lead values (over .2 mgs. 'X>i lead per liter of urine, determined on a spot sample of adequate volume and speoifie gravity by a chemist with adequate experience and equipneutj our urinary lead findings have been confixed by the Industrial Hygiene Laboratory, University of Texas Uedical Branch at Galveston, Texas)* A complete physical ex amination, including urinalysis, should be performed on .....all workers to be treated with EDTA and followup examine-- tions are necessary to determine the increase in urinary lead output (if any!)* and to guard against renal damage from EDTA* At the same time, it is essential to carry out air studies and to remove lead contamination from the air* We are for tnate to have on our etaff, a Profsalonal Industrial Hy- glens Engineer, Ur* Uunson H. Tix, who is extremely anxious to design for small industrial plants, adequate ventilation aet-upa, to minimise occupational dust asposura* OHL strives to furnish a complete industrial hygiene service from the medical to the engineering* We have been most for tnate in having the help of Mr. Jim Hammond to get us star ted on the right track... ......... ...... .... It was not possible for me to attend the last Qulf Coast In dustrial Health Conference since it happened to coincide with m y lest manic spell during which I felt it necessary to start the lab and could not possibly have kept still long enough to have sat through conference. It is rocking long well now for OHL, and I believe that after a 2-3 year sweating-out period, we shall become the leading Industrial Hygiene factor in the American Industrial Frontier - The Golden Gulf Coaat* I enjoyed bearing from you. Sincerely, N22159 // William U. QieS3el, M.D.
