Abstract To investigate the contribution of vehicle emissions to PM_2.5 in roadside micro-environments in Wuhan, daily PM_2.5 filter samples were collected from different roadside microenvironments (urban roadside, ring roadside) and background site from October 18^th to October 27^th, 2019 in Wuhan. Chemical components of the PM_2.5 samples include elements, carbonaceous materials, and ions were determined. The motor vehicle exhausted PM_2.5 were also collected and analyzed to provide localized source profile for the fitting of chemical mass balance (CMB) model. The results showed that the vehicle exhausted PM_2.5 was dominated by OC and EC. Mass fraction of OC in PM_2.5 from gasoline vehicles was 1.14 times that from diesel vehicles, while the EC from diesel vehicles was 1.08 times that from gasoline vehicles. The fine organic aerosol concentration in roadside was higher than the other sites and largely originated from vehicle exhausts. Concentrations of Fe, Si, and Al at the outer loop line roadside were higher than those at inner-loop urban roadsides. CMB source appointment results showed that the contribution of vehicle emissions to PM_2.5 at the outer loop and inner-loop urban roadsides was 35.20% and 38.89%, respectively, nearly twice that at background site. The sources of PM_2.5 varied with different roadside microenvironments, with vehicle emissions and secondary aerosol had a higher contribution at the inner-loop urban roadside than the outer loop roadside, while dust increased in importance at the outer loop roadside.

Key words： roadside PM_2.5 chemical mass balance (CMB) source apportionment
