The concentration of Sb in plants depends on several factors. The first of these factors is the phytoavailability of Sb in soils. The concentration of Sb or other heavy metals in plants is often positively correlated with their solubility (as determined by extraction with water or electrolyte solutions) (Hammel et al., 2000, Song et al., 2004).
