“…According to XRD analyses (Bruker AXS D8 Advance, Karlsruhe, Germany), the main minerals in the soil were quartz, calcite, muscovite and chlorite. [34] The soil was the same that had been used in a previous study on Sb reduction in a microcosm batch experiment. [22] Column experiments The experiments were performed using four chromatographic polypropylene columns (Büchi, Switzerland) with an inner diameter of 4 cm.…”

Environmental context. Contamination of shooting range soils by antimony (Sb) released from corroding ammunition has become an issue of public environmental concern. Because many of these sites are subject to waterlogging and consequently limited aeration, we performed column experiments with contaminated shooting range soil to investigate Sb mobility under such conditions. The results are important for our understanding of the risks arising from Sb-contaminated soils, and also for the derivation of appropriate management strategies for such sites.Abstract. Despite the environmental risks arising from antimony-contaminated sites, critical factors controlling the mobility of Sb in soils have still not been fully identified to date. We performed column experiments to investigate how reducing conditions affect Sb leaching from a calcareous shooting range soil, with a special focus on the relationship between Sb release and mineral dissolution processes. After eluting the columns for 5 days with 15 mM lactate solution at a flow rate of 33 mm day À1 , the flow was interrupted for 37 days and then resumed for another 5 days. With the transition to moderately reducing conditions (,300 mV) after 1 day of flow, effluent Sb V and manganese (Mn) concentrations showed a concomitant increase, providing evidence that Sb V associated to these phases was released by the reductive dissolution of Mn minerals. The release of Sb V was counteracted by the reduction to Sb III , which was first scavenged by iron (Fe) (hydr) oxides and then slowly liberated again when the redox potential further decreased to Fe-reducing conditions. Laser ablation-inductively coupled plasma-mass spectrometry revealed the presence of an initial pool of Sb associated with Mn-containing, Fe-free phases, underpinning the important role of the latter in addition to Fe (hydr)oxides as Sb sorbents.

“…This observation agrees with the EDTA-extractable Pb and Cd concentration, which were 1.7-fold and 1.5-fold higher, respectively, in the acidic soil compared to the calcareous soil. This finding can be attributed to the high pH of the calcareous soil, which reduced Pb and Cd mobility in soil and particularly, in the case of Pb, due to specific adsorption processes on Fe and Mn (hydr-)oxides (Conesa et al, 2010). Additionally, the high CaCO 3 content of the calcareous soil could have reduced Pb plant availability as Pb may have precipitated in form of low soluble Pb-carbonates with a low solubility product.…”

“…A similar effect may explain the difference in both Sb(III) and Sb(V) bonding affinities among the five sediments. A few sequential extraction studies and physical analyses of sediments show a favorable association of Sb with Fe oxides (Crecelius et al, 1975;Brannon and Patrick, 1985;Chen et al, 2003;Gál et al, 2007;Denys et al, 2009;Conesa et al, 2010;Wang et al, 2011). Crecelius et al (1975) and Brannon and Patrick (1985) found that large proportions of Sb in sediments were bound to extractable (both non-crystalline and crystalline) fractions of Fe and Al.…”

The present work investigated the adsorption of Sb (III) and Sb(V) on five sediment samples (Pearl River, Yangtze River, Yellow River, Yongding River, and Liao River) from typical water systems in China and the adsorption of Sb(V) on Pearl River sediment with different organic carbon (OC) fractions using batch experiments. In order to assess the contributions of sedimentary organic components to the overall adsorption of pentavalent Sb on sediments, one sediment sample was treated by commonly used chemical and physical methods to remove different organic components. Experimental data of Sb(III) and Sb(V) adsorption on five sediments were successfully modeled using the Freundlich (r 2 > 0.96) isotherm. In general, the sediments with high Fe and Al oxide contents and total organic carbon (TOC) had higher Sb(III) and Sb(V) adsorption than the sediments containing small amounts of Fe and Al oxides and TOC. Dissolved organic carbon (DOC) in sediment promoted the adsorption of Sb(V), and humin fractions and black carbon-like material in sediment had a high affinity for Sb(V).
