Karim Ahmed NRDC [stamped, DEC 3 1979] Carbon, . . . First of all, thank you for attending our Comp. Tox. seminar. I hope to see you often, at your convenience. Do you have any literature on pathology from inhaled carbon? One can hardly lean on such a thin reed but some reports indicate that carbon absorbates may be biologically neutralized. What recent data have you found? J. Thank you for the book! 12/3/79 arr
