Short summary
Understanding the mixing state of ambient black carbon (BC) and the chemical characteristics of its associated coatings is important to evaluate BC fate and environmental impacts. This study reports fresh secondary organic aerosol (SOA) formation near traffic emissions during daytime. Our observations suggest that BC was unlikely the major condensation sink of SOA, and a portion of SOA condensed on BC surface was chemically different from other SOA particles that were externally mixed with BC.
