A novel multilinear engine (ME-2) model was applied to the PM2.5 dataset observed in the Pearl River Delta (PRD) of China in 2015 and identified the sources of secondary sulfate (21 %), vehicle emissions (14 %), industrial emissions (13 %), secondary nitrate (11 %), biomass burning (11 %), secondary organic aerosol (7 %), coal burning (6 %), fugitive dust (5 %), ship emissions (3 %) and aged sea salt (2 %).
