Kehoe, M.D, The Kettering Laboratory University of Cincinnati Department of Preventive Medicine and Industrial Health College of Medicine - Eden Avenue Cincinnati 19, Ohio Dear Bob: Thank you for your letter of August 7th; please accept my apologies for the delay in replying. I have been out of the office the major portion of August. First, may I say I would certainly be very pleased to meet and discuss with you the control of lead, and concur with the idea of having a cross check of our laboratories. You mentioned you had consulted with the General Elec tric Company at Edmore, Michigan. I don't know whether they informed you of this, but we have done no consult ing work for them; in fact, I have never been to the city of Edmore. We have performed their lead and mercury analyses, which they have collected and sent to us for lead and mercury determination. We have supplied the vacutainers or urine bottles for their sample collection. As they may have told you, we have never been pleased with our analytical method for blood mercury, until re cently when we have gone to another method. We had re peatedly suggested that they use another laboratory, and questioned what value this information was to them. We recently received an inquiry from Dr. Goldwater (Col umbia) asking us for the analytical methods we used, as he had been retained to do some consulting work at the Edmore plant. I would be pleased to discuss in detail the blood lead program we use in industry. In summary, it consists of the following practice: To: Dr. R. A,. Kehoe August 20, 1963 2 At a, blood lead value of 0.09 mg. of lead per 100 grams. It Is mandatory that the person be re moved from his job and placed in the care of a phy sician. At a value of 0.08 mg, per 100 grams, it is left to the discretion of the physician as to wheth er the person should continue to work in his usual job while under close medical supervision. If a substantial percentage of the people works Ing in any area are over 0.05, steps are taken to improve the environment of the work area. You indicated in your letter you had a busy schedule and would not be free until in October. Do you plan on attending the IHF meeting which is the week of October 22nd? I hav meetings scheduled for Monday and Tuesday, however Wednesday or Thursday are open, if they are convenient for you. With kindest regards. Very trjiTy yours. GDC : f S' : George D. Clayton 002028?
