A comparison of PM1, PM2.5 and PM10 concentrations at breathing height in a residential area of Zagreb, Croatia

Particulate matter 1-minute mean mass concentrations where measured by the University of Zagreb’s Faculty of Science building at the hight roughly corresponding to pedstrian inhalation hight (1.7 m above the ground). PM1 concentrations slightly exceed the yearly limit as set by the European Union. However, the average PM10 concentration for this location is lower than the European Limit. The average PM1 (27.9 µg m-3) is comparable to the estimated exposure of a cyclist in the town of Mol (Belgium).
