“…The similar co-accumulation of As and Sb was reported in another As hyperaccumulator, P. cretica (Feng et al 2011). The Sb concentration in the pinnae reached 1516 mg kg −1 , which is apparently higher than that of roots (Feng et al 2011). However, several studies on P. vittata found that Sb mostly accumulates in the root with limited upward translocation (Mathews et al 2011, Tisarum et al 2014.…”

“…P. vittata can also adsorb a large amount of Sb, which mainly accumulates in the pinnae as a mixture of SbIII and SbV. The similar co-accumulation of As and Sb was reported in another As hyperaccumulator, P. cretica (Feng et al 2011). The Sb concentration in the pinnae reached 1516 mg kg −1 , which is apparently higher than that of roots (Feng et al 2011).…”

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.

“…Our previous results showed that the uptake of Sb in Pteris cretica L. (Cretan brake fern) was enhanced by increasing As levels, but As was suppressed by high levels of Sb, accompanied with decreased As and enhanced Sb levels in the cytosol fraction (Feng et al, 2011). However, we did not know whether the copresence of As and Sb in growth media would affect their speciation transformation, as well as whether and where Sb and As methylation occur in the soil-plant system.…”

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.

“…P. vitatta was observed to show excellent tolerance to heavy metals such as Cd, Ni, Pb, Zn, Se, Sb, etc. with effective arsenic hyperaccumulation capacity and is recognized as potential material for the co-contamination remediation (Fayiga et al, 2004;An and Huang, 2006;Srivastava et al, 2009;Feng et al, 2009Feng et al, , 2011.…”
