PM1 and PM2.5 samples were collected separately on prebaked quartz-fiber filters using dedicated high-volume samplers for 12 h (days and nights). The mean OC concentrations ranged from 2.23 to 5.68 μg m-3 (PM1) and from 2.32 to 6.91 μg m-3 (PM2.5), with the maximal concentrations of 12.98 μg m-3 (PM1) and 16.21 μg m-3 (PM2.5). The mean EC concentrations ranged from 0.13 to 0.71 μg m-3 (PM1) and from 0.15 to 0.85 μg m-3 (PM2.5), with the maximal concentrations of 2.28 μg m-3 (PM1) and 2.83 μg m-3 (PM2.5). 64 – 94 % of OC and 69 – 86 % of EC in PM2.5 belonged to the PM1 subfraction. Winter OC and EC were higher than summer. PMF modeling with three sources of OC and EC – secondary organic aerosol (SOA), biomass burning (BB), and vehicle emissions (veh) – each split into the local and remote components, provided SOA concentrations consistent with conventional estimates based on the OC and EC concentrations. Winter SOA OC and BB EC were higher than summer. Local SOA OC and EC were larger than the remote, local BB OC was smaller, and local BB OC was smaller than the remote. HYSPLIT analysis showed that the air masses were inflowing to the monitoring site relatively evenly from all directions, with mild prevalence of western inflows at Diabla Góra and west- and southward inflows at Zielonka. PM1 OC and EC concentrations measured at Diabla Góra and Zielonka were only slightly higher than those measured at other worldwide locations, while PM2.5 OC and EC concentrations were comparable. particulate matter organic carbon elemental carbon source apportionment secondary organic aerosol biomass burning vehicle emissions Full Text Supplementary Files Markersupinfofinal.pdf Cite Share Download PDF Status: Posted Version 1 posted You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
