- •
BC concentrations and mixing states were investigated using an SP2 in urban Beijing.
- •
BC fraction in PM2.5 decreased during haze though its concentrations increased.
- •
The number fraction of thickly-coated BC increased significantly during haze periods.
- •
The light absorption of BC was amplified in response to the increasing ambient RH.
