An assessment of air quality of Belgrade was performed by determining the trace element content in airborne PM10 and PM2.5 in two years period. Samples were collected at two locations in a heavy polluted area. The concentrations of Al, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn were determined with AAS. Results indicated that the ambient concentration of Zn in the PM10 and PM2.5 was the highest (1389.18 and 1998.00 ng m-3 respectively). Also, the highest enrichment factor (EF) value was obtained for Zn, folowing with high EF for Cd and Pb in PM10, reflecting the importance of anthropogenic inputs. The limit values of toxic trace elements from WHO and EC Air quality guidelines were not exceeded except for Ni.Physical chemistry 2006 : 8th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 26-29 September 200
