POLYCYCLIC AROMATIC HYDROCARBONS IN THE EXHAUST OF GASOLINE AND DIESEL VEHICLES

The precision and separation efficiency of current analytical methods for the sampling and analysis of polycyclic aromatic hydrocarbons (PAH) in the exhaust of automobiles were studied. The sampling of the PAH is done by condensing the total exhaust gas flow. The PAH collected are concentrated by known liquid-liquid extractions, purified by silica gel and separated into fractions using Sephadex. Two quantitative analytical methods are used, the advanced technique of glass capillary gas chromatography and thin-layer chromatography coupled with in situ fluorescence spectrometry. The PAH contents in the exhaust gas of several diesel and gasoline cars are compared for different driving cycles.
