The article deals with the possibility of comparison of enrichment factors in air aerosols (PM10) and in the street dust, which is influenced by air pollution. For Pb and Sb, the same value of enrichment factor for both matrices was determined. The highest enrichment index (> 100) in air aerosols was found for Cd, Sb, and As, and also for Pb, and Zn (approximately 100). Enrichment factor shows significant differences in the summer and winter period, for Cd, Sb, As, Pb, and Zn it is > 2x higher in winter. Enrichment factor in street dust was also evaluated using geochemical background of soils from Olomouc. It was found that the highest value of enrichment factor is achieved by Cu, which comes from transport (probably bus operation).
