Kehoe University o f Cincinnati College o f Medicine Department o f Environmental Health Kettering Laboratory Eden and Bethesda Avenues C incinnati, Ohio 45219 ' Dear Dr. Kehoe: , __ Many thanks for your lette r o f May 20 and the detai led answers to my questions. I see that we are largely in agreement, certainly on the major points. I was p articularly interested in your promise to discuss the analysis o f lead in blood w ith your analytical group. I would welcome any suggestions they might have w ith respect to the analyses o f lead in blood on the smallest samples consistent w ith accuracy and precision. I men tioned a study that we propose to undertake. As part o f this study, I fear we w ill have to do at least a few analyses o f lead in hair. 1 have designed the study in such a way that we can compare lead in hair, ALA, blood lead and EDTA m obilization simultaneously in a small group o f patients. I am hopeful that, useful data may come from this. My greatest interest, however, is in a procedure for lead in blood on a minimal amount o f blood. Hoping to hear from you again and many thanks for your advice, I am Yours sincerely, JJC :o v K 0020247 N20677
