- •
1H NMR spectroscopy was used to study urban organic aerosols in PM2.5.
- •
Water and alkaline soluble components of urban organic aerosols have been compared.
- •
1H NMR spectral features and their seasonal variability have been investigated.
- •
Urban OA does not fit marine, secondary and biomass burning source fingerprints.
- •
Local anthropogenic origin of WSOM and ASOM have been suggested.
