Acidic anions in PM10 particle fraction in Zagreb air, Croatia.
This paper presents the results of 7 years continuous measurement of acidic anions chlorides, nitrates, and sulphates in PM(10) particle fraction in the city of Zagreb, Croatia. The mean annual mass concentrations of the investigated anions in PM(10) particle fraction varied from 0.28 to 0.95 microg/m(3) for chlorides, from 3.21 to 7.87 microg/m(3) for nitrates and from 3.98 to 9.71 microg/m(3) for sulphates. The concentration levels of all measured anions showed significant seasonal differences. The most contributing to the PM(10) mass were sulphates, then nitrates, and then chlorides. The mobile source emission was an important contributor to particle mass.
