英文摘要	In this work, we conducted a study of the stable carbon isotope ratios of total carbon (δ13CTC) for submicron aerosol particles (<1 μm) that were collected year round (2014) at a hemiboreal forest site in Lithuania. Higher δ13CTC values characterised the seasonal variation in δ13CTC during the cold season (average −26.9 ± 0.7‰) with lower values observed during the warm season (−27.6 ± 0.6‰). The total carbon (TC) concentration was below 8 μg/m3 during the one-year measurement period. There was one pollution event in autumn when concentrations reached up to 14.8 μg/m3. In addition to the offline analysis of the filter samples, the online measurements of aerosol physical and chemical properties were conducted from 15 May to September 27, 2014 by operating the Aethalometer AE-31 and a quadrupole-type Aerosol Chemical Speciation Monitor (ACSM). Source apportionment was conducted by analysing the ACSM mass spectra using Positive Matrix Factorisation (PMF). Three main factors were derived, pointing to primary emissions from biomass burning along with the secondary formation of less and more oxygenated organic aerosol of biogenic origin. A comparative analysis of δ13CTC with organic carbon (OC), elemental carbon (EC), and organic markers justified two dominant sources (biomass burning and fossil fuel combustion) of aerosol particles at the hemiboreal forest site during the cold season. © 2022 Elsevier Ltd
