dc.descriptionDebrecen is an average middle European city from the point of view of aerosol pollution. Its locationmakes the city an ideal place for observing aerosol transport processes. Systematic investigation ofatmospheric aerosol of the east-Hungarian region has been performed in the Institute of NuclearResearch of the Hungarian Academy of Sciences for 20 years by accelerator based elementalanalytical technique. As a complementation of this research we observed the size distribution andshort-term time variation of the elemental component of fine (PM2.5) and coarse (PM10-PM2.5) urbanaerosol in the frame of sampling campaigns during 2007 and 2008 in a downtown site of Debrecen.Meteorological parameters were also recorded parallel to the aerosol sampling. Elementalconcentrations (Z ≥ 12) were determined by particle induced X-ray emission (PIXE) analyticaltechnique at the Laboratory of Ion Beam Applications (IBA) of the ATOMKI. On the obtaineddatabase six sources of the urban aerosol were identified: 2 types of soil, domestic heating, sulphateoriginating from long range transport processes, an unidentified source enriched with chlorine andtraffic. Emission episodes were also observed. The short-time variation of urban aerosol combinedwith meteorological data and with mass size distribution serves as a basis to reach a betterunderstanding of the aerosol sources in receptor areas, to select local emission and long rangetransport episodes, to follow the evolution of aerosol, and to make a better estimate on the healthimpact.
