Short summary
This work highlights that trace metals and refractory black carbon (rBC), and their inclusion in a source–receptor model, can provide important insight into the source apportionment of carbonaceous aerosols. In Singapore, we evidenced that 90 % of rBC originated from traffic/industrial emissions. The association of aged OA with K and Rb underlines the influence of regional biomass burning sources, while rBC fragmentation patterns and V/Ni were used to identify industrial and shipping pollutants.
