- •
18 China III and China IV diesel trucks operating in Beijing were monitored using a PEMS.
- •
EFs for the PM2.5 chemical components of the tested diesel trucks were characterized.
- •
Carbonaceous compounds, WSIs and elements shared approximately 91% of the PM2.5.
- •
The EC/OC of the China IV diesel trucks were higher than those of the China III diesel trucks.
- •
The EFs for the PM2.5 and OC under non-highway were higher than those under highway.
