<div class="htmlview paragraph">Individual polynuclear aromatic hydrocarbons (PAH) were measured in the exhaust gas from gasoline and gasoline/methanol blend fueled vehicles. Driving cycle tests as well as constant speed conditions were used.</div> <div class="htmlview paragraph">Exhaust emission samples were collected on filters together with a condenser. Eleven PAHs were quantified by gas chromatography and FID. PAHs in the fuels were also determined.</div> <div class="htmlview paragraph">There was no consistent difference in the amount of PAH-emission when the two fuels, gasoline and the gasoline/methanol blend, were compared. The emissions contain specific PAHs that cannot be found in the fuel.</div>
