In this study, four 75- or 80-cm-deep soil profiles in the vicinity of the Xikuangshan Sb smelter were sampled and studied by combination of bulk chemical analysis, sequential extraction procedure, and speciation analysis of Sb and As, which are in order to assess the vertical mobility of metal/metalloid contaminants (Sb, As, Cd, and Hg). The heavy contamination in the soil profiles is mostly located in the uppermost soil layers enriched in organic matter (<40cm) and exhibited downward migration in the soil profiles. Sb and As, being substantially bound in the exchangeable fractions by sequential extraction studies, showed significant mobility in the profiles. Sb(III), Sb(V), As(III), and As(V) were found in all of the soil samples, and certain methylated states of Sb (TMSb) and As (MMA, DMA) were also present in the lower layer soil samples.
