“…The standard reference materials were ground and evenly spread on 3 M tape, whereas the soil samples were pressed into flakes for XANES analysis. The adsorption edge of the XANES was used to distinguish between Sb III and Sb V (Takaoka et al, 2005). Linear combination fitting analysis (LCF) was used to fit a combination of model compounds to unknown spectra using the Athena program in the IFEFFIT package.…”

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.

“…Data analysis was performed using ATHENA software (Ravel, 2007). The position of the XANES peak was used to distinguish Sb(III) and Sb(V) (Mitsunobu et al, 2006;Scheinost et al, 2006;Takaoka et al, 2005). Linear combination fitting analysis (LCF) was used to fit a combination of model compounds to unknown spectra.…”

“…In soil solution Sb is mainly present as pentavalent oxyanion, Sb(OH) 6 À (Filella et al, 2009c;Oorts et al, 2008). This is also the dominant form observed in contaminated soils near smelters and at shooting ranges Takaoka et al, 2005). Methylated Sb species may also play a role in soil depending on biological activity and the bioavailable inorganic Sb pool (Duester et al, 2005).…”

“…Only environmental systems containing antimony concentrations high enough for XAS analysis, such as soils around an antimony smelter, [78] affected by an antimony mine pit [79] and from shooting ranges [80] have been studied so far using these techniques. These studies found that antimony was present exclusively as Sb V and that Fe III hydroxide was probably the host phase.…”

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
