摘要：
To estimate the sources of carbonaceous particulate matter, 14C and biomass-burning marker (levoglucosan) were measured in the form of organic carbon (OC) and elemental carbon (EC) in PM2.5 that was collected in five different functional districts of Shanghai during winter 2013. Spatial variations of the contemporary proportion among different districts were evident. The results of levoglucosan in Xujiahui (XH) and Chongming (CM) agreed well with those of 14C. The results indicate that environmental protection policies should vary for functional districts within the same city to account for their different sources of emissions.
