Short summary
Water-soluble organic aerosols have significant impacts on haze formation, climate change and human health. This study investigated the characteristics of WSOC in PM2.5 in Beijing to compare the source contributions of different WSOC fractions and the influencing factors for different secondary components in WSOC. Our results help to propose control measures for WSOC during severe haze episodes and underline the importance of SOA properties and heterogeneous reactions in different seasons.
