In early spring the Baltic region is frequently affected byhigh-pollution events due to biomass burning in that area. Here we present acomprehensive study to investigate the impact of biomass/grass burning (BB)on the evolution and composition of aerosol in Preila, Lithuania, duringspringtime open fires. Non-refractory submicron particulate matter(NR-PM1) was measured by an Aerodyne aerosol chemical speciationmonitor (ACSM) and a source apportionment with the multilinear engine (ME-2)running the positive matrix factorization (PMF) model was applied to theorganic aerosol fraction to investigate the impact of biomass/grass burning.Satellite observations over regions of biomass burning activity supportedthe results and identification of air mass transport to the area ofinvestigation. Sharp increases in biomass burning tracers, such aslevoglucosan up to 683 ng m−3 and black carbon (BC) up to 17 µg m−3were observed during this period. A further separation betweenfossil and non-fossil primary and secondary contributions was obtained bycoupling ACSM PMF results and radiocarbon (14C) measurements of theelemental (EC) and organic (OC) carbon fractions. Non-fossil organic carbon(OCnf) was the dominant fraction of PM1, with the primary(POCnf) and secondary (SOCnf) fractions contributing 26–44 % and13–23 % to the total carbon (TC), respectively. 5–8 % of the TC had aprimary fossil origin (POCf), whereas the contribution of fossilsecondary organic carbon (SOCf) was 4–13 %. Non-fossil EC(ECnf) and fossil EC (ECf) ranged from 13–24 and 7–13 %,respectively. Isotope ratios of stable carbon and nitrogen isotopes wereused to distinguish aerosol particles associated with solid and liquidfossil fuel burning
