Relationship Between 4-Day Air Mass Back Trajectories and Metallic Components in PM10 and PM2.5 Particle Fractions in Zagreb Air, Croatia

This paper presents a study on the relationship between trace metal concentrations and the state of the atmosphere at the Croatian EMEP station Puntijarka, Zagreb. PMio and PM2.5 particle fractions are hazardous in terms of morbiditv and hospitalization due to cardiovas-cular and respiratorv diseases, and in terms of total mortalitv. In Zagreb, PM10 and PM25 monitoring started on a daily basis at a sampling site located in the northern, residential part of the city. Trace metal concentrations were determined from daily samples. Air mass back trajectories were used to determine particulate air pollution from local and remote sources. The investigation has shown a statis-tically significant association between air mass back trajectories and metallic air concentration levels.
