Carbonaceous species in atmospheric aerosols from the Krakow area (Malopolska District): carbonaceous species dry deposition analysis

Organic and elemental carbon content in PM10 was studied at three sites in Malopolska District representing the city centre (Krakow), rural/residential (Bialka) and residential/industrial environments (Krakow). The PM10 samples were collected during the winter time study. The highest concentrations of carbonaceous species were observed in Skawina (36.9 μg·m-3 of OC and 9.6 μg·m-3 of EC). The lowest OC and EC concentrations were reported in Krakow (15.2 μg·m-3 and 3.9 μg·m-3, respectively. The highest concentration of carbonaceous species and the highest wind velocities in Skawina influenced the highest values of the dry deposition fluxes. Correlations between OC, EC and chemical constituents and meteorological parameters suggest that a) Krakow was influenced by local emission sources and temperature inversion occurrence; b) Bialka was under the influence of local emission sources and long-range transport of particles; c) Skawina was impacted by local emission sources
