Short summary

We apply radiocarbon source apportionment of more volatile organic carbon (mvOC) to winter aerosol samples from six Chinese cities. We find a consistently larger contribution of fossil sources to mvOC than to secondary or total organic carbon. Fossil mvOC concentrations are strongly correlated with primary fossil OC but not with secondary fossil OC. The variability in nonfossil mvOC seems to be related to both primary and secondary biomass burning sources.
