- •
δ34S values from potential sources in PM2.5 were determined for the first time in Nanjing.
- •
Sulfur in PM2.5 included the primary sulfate from coal combustion and vehicle exhaust as well as the secondary sulfate from SO2 oxidation.
- •
The oxidation pathways of SO2 to sulfate in PM2.5 were identified based on sulfur isotopic fractionation coefficients between SO2 and sulfate.
