Kehoe University o f Cincinnati College o f Medicine Department o f Environmental Health Kettering Laboratory Eden and Bethesda Avenues C incinnati, Ohio 4521 9 ' Dear Dr. Kehoe: , * Many thanks for your letter o f May 20 and the detailed answers to my questions. I see that we are largely in agreement, certainly on the major points. I was p a rticularly 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. I 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 th a t(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, JJCrov N22107
