Abstract

This study deals with the determination of heavy metals, anions and cations in atmospheric aerosols at four heavily polluted sites in Samsun city, Turkey. The anions Cl-, Br-, NO3- and NO2- and cations Na+, K+ and NH4+ in the samples were determined by ion chromatography using a potentiometric detector with ion selective electrodes. Flame and graphite-furnace Atomic Absorption Spectrometer was used for the determination of Pb, Cu, Zn and Fe. The average values of Cl-, NO3-, NO2-, Br-, Na+, K+ and NH4+ concentrations in the samples were 4.58±1.30, 7.42±1.32, 0.86±0.10, 0.28±0.05, 0.77±0.13, 0.72±0.06, and 1.08±0.09 µg/m3 respectively. The average values of Zn, Cu, Fe and Pb concentrations in the samples were 2.32±0.21, 1.71±0.14, 2.29±0.18, and 2.46±0.22 µg/m3 respectively.
