- •
The maximum of PSD shifted from 60 nm to greater than 100 nm in pollution episode.
- •
SNA were the main contributor to the mass increase of the 100–1000 nm particle.
- •
SO42 − was most likely formed via heterogeneous reactions.
- •
Homogenous reaction between HNO3 and NH3 dominated the formation of nitrate.
- •
Secondary transformation was the main reason for the pollution episodes.
