Characterization of the Air Quality in Split, Croatia Focusing upon Fine and Coarse Particulate Matter Analysis

The study presents statistical analysis of air quality parameters for a 5-year period including PM2.5 (particles with an aerodynamic diameter, da < 2.5 μm) and PM10 (da < 10 μm) concentrations measured at three stations in Split region, along with NO, NOx, NO2, SO2 and black smoke data. Average concentrations of PM2.5 at three different stations were 28.2, 19.9 and 14.3 μg m-3, while those for PM10 were 17.8, 25.8 and 15.2 μg m-3. Generally high correlations between PM2.5 and PM10 (0.62 and 0.54 respectively) were determined between industrial (A2) and residential (A3) stations, while lower correlation (0.22 between PM2.5 and PM10) was noticed at station placed in traffic and industrial area (A1). Contributions of different sources were determined using multivariate receptor modelling (Principal Component Analysis, Cluster Analysis) and it is found that major source of pollution are in accordance with stations position. Comparison of particle mass concentrations with those reported for different European cities indicate lower loading with PM in Split Region.
