“…Little data exist for natural waters and unpolluted soils and sediments. [61,62] Measured concentrations are low and antimony seems to be methylated less extensively than other elements, such as arsenic. However, recent results might change the current perception.…”

Environmental context. Antimony first attracted public attention in the mid-1990s amid claims that it was involved in Sudden Infant Death Syndrome. A substantial number of papers have now been published on the element and its behaviour in the natural environment. However, many key aspects of the environmental chemistry of antimony remain poorly understood. These include critical areas such as its ecotoxicology, its global cycling through different environmental compartments, and what chemical form it takes in different environments. More focussed research would help the situation. The present review highlights several areas of environmental antimony chemistry that urgently need to be addressed.Abstract. The objective of the present article is to present a critical overview of issues related to the current state of knowledge on the behaviour of antimony in the environment. It makes no attempt to systematically review all published data. However, it does provide a list of the main published reviews on antimony and identifies subjects where systematic reviews are needed. Areas where our knowledge is strong -and the corresponding gaps -in subjects ranging from total concentrations and speciation in the various environmental compartments, to ecotoxicity, to cycling between compartments, are discussed, along with the underlying research. Determining total antimony no longer poses a problem for most environmental samples but speciation measurements remain challenging throughout the process, from sampling to analysis. This means that the analytical tools still need to be improved but experience shows that, to be useful in practice, this should be directly driven by the requirements of laboratory and field measurements. Many different issues can be identified where further research is required, both in the laboratory and in the field, the most urgently needed studies probably being: (i) long-term spatial and temporal studies in the different environmental compartments in order to collect the data needed to establish a global biogeochemical cycle; (ii) laboratory studies of antimony interactions with potential natural binders; (iii) reliable ecotoxicological studies. Montserrat Filella is a chemist and teaches Environmental Chemistry at the University of Geneva, Switzerland. Her main research interests focus on the understanding of the physicochemical processes regulating the behaviour of chemical components in environmental and biological compartments, mainly by combining computer modelling with field and laboratory measurements. The three main axes of her research concern the study of: colloids in natural waters, natural organic matter (quantification and interaction with trace elements) and Group 15 elements. She is also interested in other topics

“…Recently, studies on the characteristics of Sb in the soil and plants have significantly increased, with high concentrations of Sb in some plants (Vaculik et al 2013). Therefore, excess Sb in soil may also be a risk to the environment and human health (Filella et al 2007, Shotyk et al 2005, Xiao et al 2015. A series of studies on the uptake of Sb by wheat, oat, and rye was reported by Shtangeeva et al (Shtangeeva et al 2014a, Shtangeeva et al 2014b, Shtangeeva et al 2012a, Shtangeeva et al 2012b), thereby providing a foundation for understanding the plant uptake of Sb.…”

Arsenic (As) and antimony (Sb) are chemical analogs that display similar characteristics in the environment. The As hyperaccumulator Pteris vittata L. is a potential AsSb co-accumulating species. However, when this plant is exposed to different As and Sb speciation, the associated accumulating mechanisms and subsequent assimilation processes of As and Sb remain unclear. A 2-week hydroponic experiment was conducted by exposing P. vittata to single AsIII, AsV, SbIII, and SbV or the co-existence of AsIII and SbIII and AsV and SbV. P. vittata could co-accumulate As and Sb in the pinna (>1000 mg kg −1 ) with high translocation (>1) of As and Sb from the root to the pinna. P. vittata displayed apparent preference to the trivalent speciation of As and Sb than to the pentavalent speciation. Under the single exposure of AsIII or SbIII, the pinna concentration of As and Sb was 84 and 765 % higher than that under the single exposure of AsV or SbV, respectively. Despite the provided As speciation, the main speciation of As in the root was AsV, whereas the main speciation of As in the pinna was AsIII. The Sb in the roots comprised SbV and SbIII when exposed to SbV but was exclusively SbIII when exposed to SbIII. The Sb in the pinna was a mixture of SbV and SbIII regardless of the provided Sb speciation. Compared with the single exposure of As, the coexistence of As and Sb increased the As concentration in the pinna of P. vittata by 50-66 %, accompanied by a significant increase in the AsIII percentage in the root. Compared with the single exposure of Sb, the co-existence of Sb and As also increased the Sb concentration in the pinna by 51-100 %, but no significant change in Sb speciation was found in P. vittata.

“…Previous studies of Sb speciation primarily involved soils with relatively low levels of Sb (Filella et al, 2007), whereas little work has focused on media with high levels of Sb. In addition, the limited reports of high Sb speciation were based on analyses of only samples of certain types, which may not allow for insights into the speciation and transformation of Sb in the environment and biological systems, e.g., the soil-plant system, and reveal the effect of such bio-factors as rhizospheres.…”

“…However, those in the case of Sb are far to be resolved, despite that organic Sb have been occasionally detected in some studies. It appears that Sb can be methylated by bacteria and fungus (Filella et al, 2007). For example, biomethylation of Sb by the filamentous fungus Scopulariopsis brevicaulis was recently established (Jenkins et al, 1998).…”

a b s t r a c tThe speciation changes of antimony (Sb) in soil-plant system are largely unknown as compared with those of arsenic (As). In this study, indigenous plants and associated soils were sampled at the Xikuangshan Sb mine (XKS), China. The Sb in the soils (441-1472 mg/kg) were far greater than As (32-354 mg/kg), and the Sb and As availabilities in the soils, were 5.5% and 3.9% in average, respectively. HPLC-ICP-MS revealed the presence of four species of Sb in the soils and plants, including Sb III , Sb V , TMSb and UnkSb (unknown). The use of XANES revealed that the UnkSb consisted of inorganic Sb in the form of Sb V . Inorganic Sb were prevalent in the soil and plant samples at the eight sites, whereas TMSb was observed in only a few of the rhizosphere soils, and, in plants at a few of the sites, primarily in the leaves and to a lesser extent in the stems. Arsenic was detected in the soils primarily as inorganic forms, while, DMA was detected in high proportions in all of the plant tissues at all of the sites. The methylation of Sb was far less than that of As in the indigenous plants at XKS. The results suggest that As and Sb differ in transformation characteristics in the soil-plant system in XKS.
