“…[1] As a consequence, it is also increasingly released into the environment, potentially leading to soil contamination of more than several thousand milligrams per kilogram in places where it is mined, used and disposed of. [2][3][4] A major source of Sb input into the environment are shooting activities, as lead bullets contain ,2 to 5 % of metallic Sb as a hardener. [1,5] In Switzerland, for example, 10 to 25 tonnes (,10-25 Mg) of Sb enter the pedosphere every year on more than 2000 shooting ranges [6,7] ; and in the United States, shooting activities deposit ,1900 tonnes (,1.9 Gg) of Sb annually [8] on ,12 000 firing ranges.…”

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.

“…bioavailability, and the operational speciation of Sb in soil were investigated by sequential chemical extractions of soil and by including the soil to plant transfer. Antimony is not essential for plants but can be readily absorbed by plant roots when it occurs in soluble form (Baroni et al, 2000). Background Sb levels in terrestrial vascular plants range from 0.2 to 50 mg kg À1 in plant tissue (Bowen, 1979).…”

“…Our previous report has shown that an As-hyperaccumulating fern, Pteris cretica (Cretan brake fern), also exhibited a relatively high tolerance to antimonite under hydroponic culture conditions [16]. Some other Sb accumulating plants have also been reported, such as Trifolium pratense L. [17], Achillea ageratum, Plantago lanceolata and Silene vulgaris [18], however, the mechanisms of Sb accumulation in these plants are still left to be resolved.…”
