Abstract

The peroxynitrite/Fe(III)porphyrin chemical system was established firstly to investigate the effects of peroxynitrite on the metabolism of polycyclic aromatic hydrocarbons(PAHs). By comparing the conversion ratio of benzo[a]pyrene (B[a]P) in four model systems consisting of different iron porphyrins, we found that the peroxynitrite/T(p-Cl)PPFeCl system showed the highest catalytic efficiency, which conversion ratio of B[a]P reached 20.71%. We also analyzed the metabolites of B[a]P and pyrene (PN) produced from this system by HPLC and MS methods, and successfully identified the formation of nitrobenzo [a] pyrene and nitropyrene which are the special metabolites induced by peroxynitrite.
