- •
Nitrate were higher in summer and autumn than in winter.
- •
Higher WSOC/OC ratio in summer suggests that OC was more aged.
- •
Negative correlation between WSOC and RH when humidity was higher than 80% in summer.
- •
SNA contributed more to PM2.5 in summer and OM contributed more in other seasons.
- •
The OC/EC minimum ratio method was not suitable for estimating SOC in winter.
