Sažetak
This investigation aimed to compare the ambient air concentrations of PM2.5 and PM1.0 particle fractions, as well as the particle-bound carbon mass concentrations and carbon content in each particle fraction. The study was conducted within the internal scientific project “Organic content of PM1 particle fraction” funded by the Institute for Medical Research and Occupational Health (PI: R. Godec). During a three-year period (2018-2020), daily samples of airborne particles were col- lected on pre-fired quartz fiber filters at the northern, residential part of the city of Zagreb, where the main sources of particle matter (PM) and carbon species are mostly household appliances and moderate traffic. The nominal sampling flow rate was 38 dm³/min.PM mass concentrations were determined gravimetrically following the European norm EN 12341:2014. Samples were analyzed for organic carbon (OC) and elemental carbon (EC) using the thermal/optical transmittance method (TOT) with the EUSAAR_2 protocol following the European norm EN 16909:2017. During the measurement period, average PM mass concentrations were 12.9 μg/m³ and 17.0 μg/m³ for PM1.0 and PM2.5, respectively, while the mass concentrations of EC and OC were 0.76 μg/m³ and 4.55 μg/m³ in PM1.0 and 1.03 μg/m³ and 5.42 μg/m³ in the PM2.5 particle fraction. Annual mass concentrations of PM, OC, and TC (total carbon) in both particle fractions followed the sequence: 2018 > 2020 > 2019, while EC in PM1.0 and PM2.5 followed the sequence: 2020 > 2018 >2019. The average EC/OC mass ratio was higher in the PM1.0 than in the PM2.5 particle fraction. The annual average EC/OC mass ratio in both fractions was higher than 3, suggesting the presence of SOA (secondary organic aerosol) and were in the order: 2018 > 2019 >2020.
