MEDICAL RESEARCH DIVISION Te l e p h o n e : Wa b a s h s -i eoo August 17, i960 Dr. Robert A. Kehoe The Kettering Laboratory College of Medicine University of Cincinnati Eden Avenue Cincinnati 19, Ohio Dear Dr. Kehoe: I have been asked to recanmend a maximum lead content for white gasoline which has been stored or transported in containers and lines previously carrying leaded gasoline. End uses of the white gasoline would be, for example, as carriers for household insecticide sprays, household cleaning solvents, other solvent usages involving human contact, such as rubber solvent, and in stoves or lamps. Another problem is the maximum allowable concentration for lead in solvents such as hexane which would be used in recovering protein meal for human consumption frcm soybeans, peanuts, fish meal, etc. This problem is currently under consideration by UNICEF. I would appreciate very much having your thoughts on this. Sincerely, LCM:mew R. E. ECKARDT, M. D. (Wuof-bki ^-/jr FFM'
