We report source profiles with optical attenuation for paved and unpaved road dust. Road dust was enriched in anthropogenic pollutants including Sb, Cu, Zn, Co, and Pb. Paved road dust OC/EC were higher than unpaved road dust OC/EC. Cr levels in road dust indicated potential cancer risk upon inhalation.
