Short summary
The interaction between the sources and molecular compositions of humic-like substances (HULIS) at Nanjing, China, was explored. Significant fossil fuel source contributions to HULIS were found in the 14C results from biomass burnng and traffic emissions. Increasing biogenic secondary organic aerosol (SOA) products and anthropogenic aromatic compounds were detected in summer and winter, respectively.
