Abstract Forty-eight hour size segregated particulate matter samples from atmospheric aerosols in urban site of continental part of Balkans were collected during two years (in 2012nd and 2013in). Low-Pressure Cascade Impactors by Dr. Berners was used. Size segregated particulate matter in the size ranges: 0.27 ≤ Dp ≤ 0.53 micro-meters, 0.53 ≤ Dp ≤ 1.06 micro-meters, 1.06 ≤ Dp ≤ 2.09 micro-meters, 2.09 ≤ Dp ≤ 4.11 micro-meters, 4.11 ≤ Dp ≤ 8.11 micro-meters and 8.11 ≤ Dp ≤ 16 micro-meters was measured. ICP-MS was used to quantify next elements: Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Hg, Na, Ni, Mg, Mn, Mo, Pb, Se, Sb, Ti, Tl, V and Zn. Among these elements Al, Ca, Fe and Mg are dominating in coarse mode indicating natural emission sources as responsible origin, but some anthropogenic elements are noticed as As, Pb and V with their domination in fine mode indicating an anthropogenic influence.
