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 PM₁₀ particle fraction in the city of Zagreb, Croatia. The mean annual mass concentrations of the investigated anions in PM₁₀ particle fraction varied from 0.28 to 0.95 μg/m³ for...

Zusammenfassung:	This paper presents the results of 7 years continuous measurement of acidic anions chlorides, nitrates, and sulphates in PM₁₀ particle fraction in the city of Zagreb, Croatia. The mean annual mass concentrations of the investigated anions in PM₁₀ particle fraction varied from 0.28 to 0.95 μg/m³ for chlorides, from 3.21 to 7.87 μg/m³ for nitrates and from 3.98 to 9.71 μg/m³ for sulphates. The concentration levels of all measured anions showed significant seasonal differences. The most contributing to the PM₁₀ mass were sulphates, then nitrates, and then chlorides. The mobile source emission was an important contributor to particle mass.
