Settled road dust was examined to detect the presence of organic compounds. Samples were collected from a road surface near a busy road junction in the city of Ostrava, Czech Republic, once a month from May to October. The six collected samples were analyzed by gas chromatography with mass detection. The correlation analysis divided the analyzed compounds into three distinct groups. The first group, positively correlated with the traffic count consisted of phenanthrene, acenaphthene, indenol (1,2,3-cd) pyrene, benzo(k)fluoranthene, benzo(a)pyrene, benzo(ghi)perylene, benzo(a)anthracene and chrysene, all positively correlated with each other. The second group of compounds, positively correlated with each other but negatively with the traffic count, consisted of dibenzo(ah)anthracene, naphthalene, anthracene, fluoranthene, acenaphthene and fluorene. The third group consisted only of pyrene, which had a positive correlation with most of the compounds from the second group apart from dibenzo(ah)anthracene and was not correlated with the traffic count in any way.Keywords: organic compounds, road dust, traffic, PAH
