The chemical composition of two neutral, mutagenic subfractions of a diesel particulate extract sample was examined by capillary gas chromatography/mass spectrometry. Most compounds identified were polar derivatives of three- to five-ring polynuclear aromatic hydrocarbons. Ketone, quinone, carboxaldehyde, and hydroxy derivatives and their alkyl homologues were characterized. 9-Fluorenone and its C/sub 1/-C/sub 4/ alkyl homologues were the single largest family of compounds detected. Some of the compounds characterized are bacterial mutagens; the mutagenicity of others is not known at this time.
