“…Their sample precision was 2.6, 4.1, 4.4, 1.1, 1.3, 4.2, 5.5, 5.2, and 6.7%, respectively. Detail descriptions for analyzing the WSOC and ionic species can be found in our previous publications [27,35]. Fig.…”

“…Average aerosol AAE 370-950 values for typical, pollution event I, pollution event II, and the AD event were 1.3, 1.3, 1.5, and 1.4, respectively. AAE 370-950 values greater than 1.0 could indicate that the aerosol particles collected at the site was due to biomass burning (BB) emissions and the BC aerosols from traffic emissions [3,27,29,30]. Moreover, little difference in estimated BrC AAE 370-660 values was observed among the four periods, ranging from 4.2 (AD event) to 4.6 (pollution event II), suggesting that organic aerosols contributed to total aerosol absorption throughout the study period.…”

“…The origin of BrC is attributed predominantly to atmospheric humic-like substance (HULIS) (Graber and Rudich, 2006;Andreae and Gelencser, 2006;Laskin et al, 2015;Yan and Kim, 2017). In general, the atmospheric HULIS, contributes to approximately 70 % of the water-soluble organic carbon (WSOC) (Laskin et al, 2015;Park and Son, 2017), while the 40 WSOC contributes to 10-80 % of the total organic carbon contents in aerosols (Kirillova et al, 2014a;Kirillova et al, 2014b;Fu et al, 2015). However, current understanding of the optical properties, chemical compositions, and degradation processes of light-absorbing organic aerosols still remain uncertain.…”
