| Zusammenfassung: | This paper presents the results of 7years continuous measurement of acidic anions chlorides, nitrates, and sulphates in PM sub(10) particle fraction in the city of Zagreb, Croatia. The mean annual mass concentrations of the investigated anions in PM sub(10) particle fraction varied from 0.28 to 0.95kg/m super(3) for chlorides, from 3.21 to 7.87kg/m super(3) for nitrates and from 3.98 to 9.71kg/m super(3) for sulphates. The concentration levels of all measured anions showed significant seasonal differences. The most contributing to the PM sub(10) mass were sulphates, then nitrates, and then chlorides. The mobile source emission was an important contributor to particle mass. |
