This work focuses on the heavy metals contents of the size-segregated urban aerosol of the continental area of Balkans. The distribution of nano/micron heavy metals in the size-segregated urban aerosol of Belgrade center was studied during the summer-autumn of 2008. The particle size distribution in the size ranges Dp ≤0.49 μm, 0.49 ≤ Dp ≤0.95 μm, 0.95 ≤ Dp ≤1.5 μm, 1.5 ≤ Dp ≤3.0 μm, 3.0 ≤ Dp ≤7.2 μm and Dp ≥ 7.2 μm was measured. The aerosol samples were submitted to gravimetric and chemical analyses. The obtained mean mass concentration of the PM fractions was in accordance with an urban aerosol distribution. The aerosol mass concentrations were determined by gravimetric measurements (mGM) and, for heavy metals analyzed by ICP/MS.
