摘要：
We present dual carbon isotope constrained (delta C-13 and Delta C-14) source apportionment of organic carbon and elemental carbon in fine particulate matter (PM2.5) for five districts of Shanghai during the winter of 2013. The results show that spatial variations of the three source (biomass, liquid fossil fuel, and coal) apportionment of carbonaceous aerosol among different districts were evident. Overall, coal combustion, liquid fossil fuel combustion and biomass burning are the most important carbonaceous aerosols source in Pudong, Xuhui and Chongming, respectively. The results suggest that environmental protection policies should vary according to the functional areas of different sources in the same city.
