Abstract
1, 3-, 1, 6-, 1, 8-Dinitropyrenes (DNPs) and 1-nitropyrene (1-NP) in exhaust particulates from idling gasoline and diesel engines were determined using off-line sodium hydrosulfide reduction followed by HPLC with chemiluminescence detection. The mean concentrations of 1, 3-, 1, 6-, 1, 8-DNPs and 1-NP were 0.22, 0.44, 0.35 and 1.8 pmol/mg, respectively, in gasoline particulates (n=8) and 0.23, 0.23, 0.21 and 51 pmol/mg, respectively, in diesel particulates (n=7). Although the concentrations of DNPs were lower than that of 1-NP in both gasoline and diesel particulates, they cannot be dismissed as negligible because of their extremely high mutagenicity. There was a tendency toward higher DNPs and 1-NP concentrations in particulates, with the lowering of particulate concentration in exhaust gas. The total amount of DNPs and 1-NP emitted from diesel engine vehicles was considered to be remarkably higher than that of gasoline engine vehicles.
