Gas chromatographic method was used to determine the concentration of PAHs (pyrene, fluoranthene, phenanthrene, chrysene, benzo(a)pyrene and benzo(ghi)perylene) in the grass. Study materials were collected near the traffic road in Cracow. PAHs were extracted with cyclohexane. The glass column coated with Kieselgel was used tu purified the extract. The extract was concentrated on vacuum evaporator and put on the top of glass column with aluminium oxide. PAHs were determined in cyclohexane eluant by gas chromatography after concentrate. The highest PAH concentration was 23,7 µg/g (phenanthrene in the sample of the grass collected from PI. Wolności). The concentration of benzo(a)pyrene in range from 0.04 to 0.4 µg/g depended on the place of collecting sample.
