Özet

In the present work, a comprehensive chemical characterization of PM2.5 fractions of urban aerosol collected with high-volume aerosol samplers in Budapest (Hungary) and Istanbul (Turkey) was carried out from June 2010 to May 2011. The analyses included (i) gravimetric determination of PM2.5 mass concentration; (ii) trace element determination (Bi, Cd, Co, Cr, Cu, Fe, Ga, Li, Mn, Mo, Ni, Pb, Pt, Rb, Sb, Sn, Te, Tl, U, V. Zn) after microwave-assisted aqua regia and sonication-assisted water extraction by inductively coupled plasma sector field mass spectrometry; (iii) evaluation of major anions (SO42-, NO3-, Cl-) as well as NH4+ concentrations in the aerosol samples subjected to sonication-assisted water extraction by ion chromatography and spectrophotometry, respectively; iv) assessment of total and water-soluble carbons by a C/N analyzer in the samples.
