摘要：

Dichloromethane extracts of gasoline vehicle exhaust particulates were fractionated into five fractions according to polarity on a silica gel column. A moderately polar fraction showing high genotoxic activity in the Ames test was further fractionated, using high performance liquid chromatography, on a nitro column, eluted isocratically. Gas chromatography combined with mass spectrometry, flame ionization, and electron capture detection were used for analysis. Also, field desorption mass spectrometry was utilized. Oxygenated derivatives of polycyclic aromatic hydrocarbons, e. g. , 9H-fluoren-9-one, alkylfluorenones, and benzofluorenones were the most abundant species in these subfractions. Also, some halogenated aromatic compounds are reported, and quantitative data on nitroarenes are given.
