Short summary
Water-soluble humic-like substances (HULISWS) are a potential toxic component of PM2.5 for their redox activity. In this study, we measured HULISWS and associated redox activity in PM2.5 sampled during a 1-year period in Beijing and investigated their sources. We found biomass burning and secondary aerosol formation were the major contributors (> 59 %) to both HULISWS and redox activity, and the combustion-related primary sources accounted for > 70 % of HULISWS and redox activity.
