Abstract
Hemoglobin is able to oxidize polycyclic aromatic hydrocarbons, PAH's, in presence of hydrogen peroxide. Among 12 aromatic compounds tested, six were oxidized; anthracene, carbazole, dibenzothiophene, fluorene, 9-hexylanthracene and pyrene. The products were identified as aromati c ketones and sulfoxides. Effect of organic solvent concentration and hemoglobin stability were determined. (C) 1995 Academic Press, Inc.
