摘要：

This article presents the results of mass concentration of major acidic anions (chlorides, nitrates and sulphates) in TSP and PM10 particle fraction in Zagreb air measured continuously at one measuring site in 2004. The annual average mass concentrations of the investigated anions followed the order chloride <nitrate < sulphate. Significant correlations were obtained between TSP and investigated anions and between PM10 and investigated anions, the latter showing a higher correlation coefficient. The annual average mass ratio of (NO3-)/(SO42-) obtained in TSP and PM10 was >0.8, which suggests that mobile source emission was an important contributor to particle mass.
