The contributions of anthropogenic and biogenic secondary organic carbon (SOC) to total PM 2.5 mass are of interest to air quality management agencies required to demonstrate maintenance of the PM 2.5 NAAQS. Reductions of SOC can be used in conjuncti

Considerable uncertainty still exists regarding the contribution of resuspended soil and road dust to PM2.5 organic carbon (OC) in US urban areas. Contributing factors are the limited knowledge of the OC content of resuspended soils and road dusts, a

Organic aerosol measurements with high temporal resolution can differentiate primary organic carbon (POC) from secondary organic carbon (SOC) and can be used to distinguish morning rush hour traffic emissions and subsequent photo-oxidation. In the cu
