Airborne polycyclic aromatic-hydrocarbons in the city of Zagreb, Yugoslavia

The concentrations of six PAHs (benzo[a]pyrene, benzo[b]fluoranthene, ideno[1, 2, 3-c, d]pyrene, benzo[a]anthracene, benzo[k]fluoranthene and fluoranthene), and lead have been measured systematically for six winter periods from 1977/78 to 1982/83 in the urban air of the city of Zagreb. The average mass concentrations of PAHs were ∼ 10 ng m−3. The distributions of PAHs in urban air is discussed. The analytical method for PAH determination is based on filter extraction, two-dimensional thin-layer chromatography and fluorescence spectrometry ; lead is measured by atomic absorption.
