Sampling and analysis of PAH and oxygenated PAH in diesel exhaust and ambient air

Abstract : In this work, diesel engine emissions were investigated in a dilution tunnel. The gas/particle partitioning and the different size fractions of Polycyclic Aromatic Hydrocarbons (PAH) and oxygenated derivatives (oxy-PAH) were studied. In addition, measurements were carried out near a motorway in Paris for comparison to the tunnel test results. First, it is shown, that the gaseous phase of the PAH is predominant (up to 20 times) with respect to the particulate phase, and that the PAH and their derivatives are mainly adsorbed in the very fine particulate fraction (particle size under 0.4 mum) Second, the oxygenated PAH, neglected in the majority of previous studies, are predominant with respect to the PAH.
