HIGHLIGHTS

  • 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.
 

ABSTRACT


This study used flame atomic absorption spectrometry (FAAS) to determine the metallic content in 69 samples of street dust collected in various environments (viz., streets with heavy traffic, streets in residential neighborhoods, and streets near green areas and parks) of Białystok, Poland, during 2018. In descending order of average concentration, the measured metals were Fe (2,335 mg kg1), Zn (68.99 mg kg1), Mn (68.62 mg kg1), Cu (16.37 mg kg1), Pb (11.42 mg kg1), Cr (9.12 mg kg1), and Ni (5.20 mg kg1). Only Zn and Cu exhibited concentrations exceeding the geochemical background levels for Polish soil. We mapped the metallic concentrations in the samples to evaluate the spatial distribution of these elements and identified proximity to main road junctions with high traffic as a major factor. Multivariate statistical analysis (Pearson correlation, cluster analysis, and analysis of major components) revealed an association between vehicle operation, and Zn, Ni, Cu, and Cr, as these elements were found in the most traffic-congested areas. By contrast, Fe and Mn, which were detected in potentially unpolluted areas, displayed concentrations that were similar to natural ones.
