The aim of this paper is to identify the potential sources of fine aerosols in Magurele, Romania, during an intensive campaign of 2 weeks performed in August-September 2014, based on mass concentration, species proportions and specific chemical markers.Major contributors to submicronic non-refractory aerosols are organic species, ammonium and sulphate. The inorganic species have been present as salts of ammonium nitrate and ammonium sulphate, while strong influence of traffic related source has been identified during the entire measurements period from organic species analysis. Other contributions besides those mentioned above are biomass burning and two different oxidized organic aerosols.
