Dear Dr. Kehoe: It has been recommended to me that I write you for definitive information regarding toxic levels of lead in blood and urine. I am acting Medical Director of the Tube Production Plant for color tubes for the Motorola Corporation in Franklin Park, Illinois and multiple lead compounds are used in their synthesis and manufacture. In consultation with Dr. Ter Haar, associated with the Ethyl Corporation, Detroit, who is currently in research at Argonne National Laboratories, he recommended two of your articles. One was in the Journal of the Royal Institute of Public Health, voi.24, 1960, pp 81-203, and the Journal of Nutrition, voi.19, pp 579-592, 1940, regarding Spectrochemical studies of normal ranges of concentration of certain trace elements in biological materials. . If you could send me reprints of these articles and any other information regarding current status of blood serum and urine lead analyses, and their toxicologic control in their industrial applications, I would be more than grateful. Yours truly, William T. Davin, M.D. Grad. Univ. of Cincinnati Medical School (1952).
