title: Determination of polycyclic aromatic ketones in particulate emissions of internal combustion engines.
abstract: Benzanthrone (7-H-benz(de)anthracene-7-one, MW 230) and another polycyclic aromatic ketone (6-H-benzo(cd)pyrene-6-one, MW 254) are identified in particulate emissions from both air-cooled and water-cooled automobile engines operating on gasoline. The concentrations of these compounds are roughly equal to [Formula: see text] in these sources. Determination is carried out by capillary gas chromatography using glass and fused silica columns coated with SE-54, OV-1 or Dexsil 300. Results are confirmed by GC/MS. GC/MS data indicate that other polycyclic aromatic ketones are present at much lower concentrations than the two compounds described above. This is different from PAHs, where a large number of isomeric compounds are present at similar concentrations.
