Seasonal variations of carbon mass concentrations in particle matters in air of western part of Zagreb

Levels of elemental carbon (EC) and organic carbon (OC) in PM2, 5 particles (particles with aerodynamic diameter less than 2, 5 μm) in air were determined in this study. Seasonal variations of carbon mass concentrations in PM2, 5 between seasons (spring, summer, autumn and winter) were studied and compared. The monitoring site was situated in the western part of Zagreb and characterized as urban industrial site. PM2, 5 particle fraction samples were collected during 24-hour periods on working days. Small-volume air 3 samples (≈55 m ) of airborne particles were collected on quartz fiber filters pre -fired at 900°C for three hours. PM2, 5 mass concentrations were determined gravimetrically according to the HRN EN 12341 standard. Organic carbon, elemental carbon and total carbon (TC, a sum of EC and OC) in PM 2, 5 fraction were determined by the thermal-optical transmittance method (TOT) using carbon analyzer with a flame ionization detector following a NIOSH-like protocol. Statistical analysis was performed using STATISTICA 13.0. statistical software. Statistically significant seasonal variations between seasons were observed, except between winter/autumn and spring/summer period. The highest mass concentrations of PM 2, 5, EC and OC in PM2, 5 were observed during the cold period (winter and autumn), while the lowest concentrations were observed in the summer and spring. Higher OC/EC mass ratios indicated the presence of secondary organic aerosols [1-3]. References [1] C. Wu i J.Z. Yu, AtmosphericChemistryandPhysics 16 (2016) 5453- 5465. [2] C. Pio, M.
