Short summary

An assessment of chromium occurrence in particulate matter – PM₁₀, PM_2.5, PM₁, and PM_0.25 – in the city of Radom during the calendar year was presented. The seasonality of both pseudo-total chromium content and its valence speciation was examined. The seasonality of changes in Cr_tot and Cr(VI) concentrations was observed. There was a maximum in the winter season, most likely due to the greater share of fuel combustion sources. Regardless of the season, the risk levels for Radom residents were within the acceptable risk range.
