Short summary
We explore the source apportionment of PM2.5 in North China in winter using an original combination method, and coal combustion, biomass burning and vehicle emissions are identified as the largest contributors of PM2.5, accounting for 29.6, 19.3 and 15.8 %, respectively. Biomass burning emission was highlighted in the present study because of its dominant contribution to the PM2.5 burden in the Shandong Peninsula and because it is neglected in the air pollution control program.
