Abstract The first investigation of size-segregated sub-urban aerosols from the continental part of the Balkan peninsula in 11 fractions in the range of 0.0085 < Dp < 16 μm was performed from March 2012 to December 2013. Aerosols were measured at the Zeleno Brdo observatory (44° 78' 61" N, 20° 52' 22" E – 243 m above sea level), which is the highest point near Belgrade on its eastern edge, surrounded by wooded vegetation, with rural areas on its southern parts and urban areas on its north-western part. About 70% of total aerosols are fine particles, belonging especially to the PM0.53–1.06 fraction which is more intensive in the winter period. In this work, we applied tests of probability function models, for three distributions: normal, log-normal and three-parameter Weibull, by comparing expected and observed values. This model offered us the possibility to assess whether it is the dominant emission source in the vicinity of the measuring point or it is distant. Results of this test could be a significant supplement to existing multivariate mathematical models for source apportionment for more accurate estimation of the origin of emission sources, offering information on their position relative to the investigated area (local, regional or remote). The dependence of particle concentrations for each fraction investigated versus meteorological parameters was determined.
