Solid-state species of heavy metals in soils play important roles in regulating the mobility and fate of heavymetals in the environment. Therefore, accurate evaluation of metal speciations present in soils is crucial fordeveloping effective remediation strategies. In this study, we investigated metal speciations and their effects onmetal removal efficiencies in highly contaminated soils with heavy metals including As, Pb, Cu, and Zn fromsmelting and mining. Sequential extraction was employed to evaluate solid-state speciation of metals in soils andmetal removal efficiencies were evaluated by soil washing with various washing reagents. Metal removal rateswere highly affected by metal speciation in soils. In the smelter-1 soil, metals were primarily bound to amorphousoxides and relatively high removal efficiencies of metals were observed by soil washing. On the otherhand, in the smelter-2 soil, metals were mainly associated with crystalline oxides and sulfides and their removalrates by soil washing were low. In the mine soils, arsenic was primarily present as scorodite phase and othermetals were mainly present as sulfides, which resulted in low metal extraction rates by common inorganic acids.
