Carbon content in PM2.5 at a coastal measuring site in Croatia

Rijeka is the principal seaport and third largest city in Croatia. The city's economy largely depends on shipbuilding and maritime transport. Rijeka has a humid subtropical climate with warm summers and relatively mild winters with frequent rainfall and cold (bura) winds. This study is the first on particulate matter with an equivalent aerodynamic diameter smaller than 2.5 μm (PM2.5) and the carbon content in it at a coastal urban background station. Mass concentrations of elemental (EC), organic (OC) and total carbon (TC) were investigated from January 1st 2017 to August 31st 2019. Sampling was conducted during 24- hour periods from approximately 55 m3 of ambient air on quartz fibre filters pre-fired at 850°C for 3 hours. Mass concentrations of 973 PM2.5 samples were determined gravimetrically according to the standard EN 12341:2014. Carbon content was measured by the thermal-optical transmittance method (TOT) using a carbon aerosol analyser with a flame ionization detector and EUSAAR_2 temperature program operating according to the standard EN 16909:2017. The average PM2.5 mass concentration (11.1 μg m-3) did not exceed the limit value of 25 μg m-3 and the maximum was observed in winter (51.3 μg m-3). Carbon mass concentrations revealed strong seasonality having its low in summer and high in winter. The average OC/EC mass ratio values of around 6.6 pointed to the influence of secondary organic aerosols. Average TC mass contribution to the total PM2.5 mass was 33 %, of which 20 % SOC (secondary OC), 7 % POC (primary OC) and 5 % EC. The high mass contribution of SOC to total OC mass (as much as 74 %) can be explained by the warm climate suitable for photochemical reactions and the formation of SOC from sea spray.
