Sažetak
This paper presents the analysis of PAH mass concentrations measured in PM10 particle fraction (PM10 particles with aerodynamic diameter less than 10 µm) collected at one measuring site in Zagreb air over four years, and of seasonal differences in PAH mass concentrations in PM10 samples collected from 21 March 2003 to 20 March 2004. Twenty-four hour samples were taken in the northern part of Zagreb using a low-volume (50 m3) sampler with glass fiber filters. The average mass concentrations over four-year measuring period ranged for BaP from 1.17 to 1.87 ng/m3 and were below the limit value (2 ng/m3) set by the Ordinance on Recommended and Limit Air Quality Values in Croatia. The highest concentrations of all PAHs measured in PM10 samples collected from 21 March 2003 to 20 March 2004 were found in the winter and the lowest in the summer. Mass concentrations of all measured PAHs were much higher in the autumn than in the spring.
