Abstract：There was a period of heavy pollution at North China Plain in January 2018 characterized by long duration, wide range of influence and high particle number concentration. To obtain its submicron particle number size distribution during this period, a Scanning Mobility Particle Sizer (SMPS) was deployed for a continuously monitoring at a typical suburban site in the south edge of this area. The results indicated that average mass concentration of PM2.5 was 141.32μg/m3. Particle size distribution was mainly concentrated on the ultrafine size range (78.9%) of the Nucleation mode and Atiken mode, showing a decreasing unimodal distribution, and average particle number concentration was 83174cm-3. During the heavy pollution period, particle number concentration of Nucleation mode was obviously increased, accompanied by high relative humidity (90.8±4.5)%, low wind speed (1.5±0.4) m/s and low concentration of O3 (15.8±8.3) μg/m3 conversely. The clustered 48h backward trajectories showed that air masses of observation site were mainly affected by the transportation of Hubei Province, Shaanxi Province and Shanxi Province. While the potential source regions were located at the local site and the north of the observation site based on potential source contribution function and concentration-weighted trajectory analysis.
