Abstract In order to determine polycyclic aromatic compounds (PAH) in workplace air, we have tested two different trapping systems: a polytetrafluoroethylene filter coupled with XAD-2 sorbent and a Carbotrap 150 cartridge. The above sampling methods, that needed suitable flow rates for different adsorbent phases, were compared under the same collection conditions such as temperature, pollutant concentration and kind of analytes. Diesel engine exhaust gas was used as constant and uniform PAH source to test the two trapping systems in an highly polluted environment. The results indicated that the double sampler method was more efficient for the two-four condensed ring aromatic compounds analysed while the Carbotrap 150 proved more suitable for aromatic fraction present in the form of vapours.
