Sažetak
The aim of this study was to examine the five-year trend of PM2.5 mass concentrations and mass con- centrations of water soluble inorganic ions (Cl-, NO3-, SO42-, Na+, NH4+, K+, Mg2+, Ca2+) in its content. Daily PM2.5 samples were collected on Teflon and Quartz fibre filters from 2017 to 2021 at an urban background station in Croatia. Mass concentrations of PM2.5 were determined gravimetrically accor-ding to the standard HRN EN 12341:2014 (EN 12341:2014). The content of water- soluble inorganic anions and cations was determined by ion chromatography according to HRI CEN/TR 16269:2017 and HRN EN 16913:2017 (EN 16913:2017). Results showed that the annual average PM2.5 mass concentrations ranged from 7.6 μg m-3 to 10.9 μg m-3. The annual average mass concentrations of anions and cations ranged from 0.01 μg m-3 to 2.6 μg m-3, while the contribution to the overall PM2.5 mass ranged from 27.9% to 37.3%. During the five-year period of measurement, the observed PM2.5 mass concentrations as well as mass concentrations of water-soluble ions showed a decreasing trend. Also, the annual average equivalent ratio between the sum of all anions and the sum of all cations was calculated in order to evaluate the balance between the determined ionic compounds and pos-sible acidic fine particulate matter properties. Also, during each year in the five-year period, the NO3-/SO42- ratio was below 1, which suggests a higher contribution of stationary emission sources to air pollution at the coastal urban background station.
