Source apportionment of PM2.5 in Beijing during 2012-2013 Conference Paper uri icon


  • Positive matrix factorization (PMF) source apportionment modeling study was conducted for ambient PM2.5 in Beijing during 2012-2013. The source profiles of PM2.5 and the relative contribution of each source in different seasons were elucidated. Eight sources contributing to ambient PM2.5 were identified, which include metallurgical emission, biomass combustion, traffic emission, secondary sulfate/nitrate, coal combustion, Asian dust, industrial emission, and road dust From the mass concentration perspective, traffic emission and secondary sulfate/nitrate sources were higher in the winter. Asian dust and road dust were higher in the spring, and coal combustion and industrial emission were greater in the heating season compared to other seasons. Biomass combustion was dominant during the summer. This is an abstract of a paper presented at the 108th AWMA Annual Conference and Exhibition (Raleigh, NC 6/22-25/2015).
