Road-deposited sediments in an urban environment: A first look at sequentially extracted element loads in grain size fractions

► Anthropogenic enrichment of Cu, Pb and Zn in road-deposited sediments in a Hawaiian urban environment. ► Metal mass loading for Cu, Pb, and Zn was dominated by the <63 μm fraction of road sediments. ► The reducible geochemical phase was the most important component for Cu, Pb and Zn loading in road sediments.
