Short summary
Humic-like substances (HULIS), the hydrophobic part of water soluble organic material, account for ~10% of PM2.5 mass in the Pearl River Delta, China. Source analysis using PM2.5 chemical composition data revealed that secondary formation process, biomass burning, and residual oil combustion from shipping as significant sources of HULIS. Vehicle emissions contributed little to HULIS. Primary sources of HULIS appeared to be linked to inefficient combustion.
