  • Subject of this research refers to metals in road dust in Białystok (Poland).
  • Urban dust fraction is more polluted than highway dust.
  • Amount of metals in dust depended on the main road junctions with high traffic.
  • The Fe and Mn contents were similar to natural ones.


The paper presents metal contents (Zn, Cu, Pb, Ni, Cr, Mn, Fe) in Bialystok street dust collected from various environments (streets with heavy traffic, housing streets, streets located near green areas and parks). The content of metals in street dust was determined by flame atomic absorption spectrometry (FAAS). Sixty-nine dust samples were collected in 2018. The average metal content in the dust occurred in the following order: Fe (2,335 mg kg-1) > Zn (68.99 mg kg-1) > Mn (68.62 mg kg-1) > Cu (16.37 mg kg-1) > Pb (11.42 mg kg-1) > Cr (9.12 mg kg-1) > Ni (5.20 mg kg-1). Only Zn and Cu were not found at the level of geochemical background for Polish soils. Spatial distribution of metals was evaluated using metal content maps in road dust samples from Bialystok. The spatial distribution of metals has shown that their amount in dust depended on the main road junctions with high traffic. Trying to identify metal sources using multivariate statistical analysis (Pearson correlations, cluster analysis, analysis of major components), it was found that Zn, Ni, Cu, and Cr occurred in areas with the largest congestion and were associated with the operation of vehicles. In contrast, the Fe and Mn contents were similar to natural ones and occurred in potentially unpolluted areas.
