Aims: The uptake and tolerance of antimonite [Sb(III)] and antimonate [Sb(V)] were investigated in two populations of Achillea wilhelmsii, one from strongly Sb-enriched mine soil, the other from uncontaminated soil, in comparison with non-metallicolous Silene vulgaris and Thlaspi arvense. Methods: Tolerance was assessed from root elongation and biomass accumulation after exposure to a series of concentrations of Sb(III) or Sb(V) in hydroponics. Results: For all the species Sb(III) was more toxic than Sb(V). S. vulgaris was the most Sb(III)-tolerant species, and A. wilhelmsii the most Sb(V)-tolerant one. There were no considerable interspecific differences regarding the root and shoot Sb concentrations. Sb(III) and Sb(V) tolerance and accumulation were not different between the metallicolous and the non-metallicolous A. wilhelmsii populations. Sb(III) uptake was partly inhibited by silicon. Sb(V) uptake was strongly inhibited by chloride. Conclusions: There is uncorrelated variation among species in Sb(V) and Sb(III) tolerance, showing that plants sequester Sb(V) and Sb(III) in different ways. Sb(V) seems to be taken up via monovalent anion channels, and Sb(III) via silicon transporters, at least in part. The relatively high Sb(V) tolerance in A. wilhelmsii seems to be a species-wide property, rather than a product of local adaptation to Sb-enriched soil.
