Journal ArticleDOI
Release of antimony from contaminated soil induced by redox changes.
TL;DR: The results show that Sb(V) is less stable in reducing environments than commonly assumed, and may significantly increase (eco)toxicological risks arising from Sb-contaminated soils that are prone to flooding or waterlogging.
Journal ArticleDOI
Changes in Sb speciation with waterlogging of shooting range soils and impacts on plant uptake
TL;DR: Results indicate that Sb might primarily be taken up by L. perenne and as Sb(V) by H. lanatus under different water regimes, and temporary waterlogging of soil may increase the risk of trace elements entering the food chain.
Journal ArticleDOI
Diffusive Gradients in Thin Films Reveals Differences in Antimony and Arsenic Mobility in a Contaminated Wetland Sediment during an Oxic-Anoxic Transition.

TL;DR: The results of this study showed that Sb mobilization was decoupled from the Fe cycle and was, therefore, more likely linked to sulfur and/or organic carbon (e.g., most likely authigenic antimony sulfide formation or Sb(III) complexation by reduced organic sulfur functional groups).
Journal ArticleDOI
Antimony and arsenic speciation, redox-cycling and contrasting mobility in a mining-impacted river system
Scott G Johnston,William W. Bennett,Nicholas J. C. Doriean,Kerstin Hockmann,Niloofar Karimian,Edward D Burton +5 more
TL;DR: The Macleay River in eastern Australia is severely impacted by historic stibnite- and arsenopyrite-rich mine-tailings, and localised redox-driven shifts in speciation of both elements strongly influence their respective mobility and partitioning.
Journal ArticleDOI
Antimony mobility in reducing environments: the effect of microbial iron(III)-reduction and associated secondary mineralization
TL;DR: In this paper, the authors examined Sb behavior during microbially-mediated reduction and transformation of Sb(V)-bearing ferrihydrite by the dissimilatory Fe(III)-reducing bacterium, Shewanella putrefaciens (strain CN32).
