A novel method to determine the concentration and the isotopes of WSOC in aerosols is established and applied in the analysis of a severe haze in eastern China. The results show that the studied site is affected by the photochemical aging, biomass burning and dust aerosols in different episodes during the sampling period. The analysis of WSOC and its isotopes offers a great potential to better understand the source emission, the atmospheric aging and the secondary production of WSOC.
A novel method to determine the concentration and the isotopes of WSOC in aerosols is...
