- •
Radiocarbon and organic tracers were determined in a megacity of central China during an extreme haze event in 2013 winter.
- •
The contributions of non-fossil sources in OC and EC were 62% ± 5% and 26% ± 8%, respectively.
- •
The contributions of non-fossil sources in WIOC and WSOC were 61% ± 4% and 63% ± 6%, respectively.
- •
Most non-fossil SOC particles probably were derived from the atmospheric processes regarding biomass-burning.
