3. Antimony in environment3.1. Occurrence forms of antimony. Antimony is located in the VA group of the 5th period of the periodic table of elements, and there are four valence states (Sb(-III), Sb(0), Sb(III) and Sb(V)) (Filella et al., 2002a).In the surface environment and biological media, antimony usually exists in the form of Sb(III) and …

Natural concentrations of antimony (Sb) in the environment are low. Its abundance in the earth's crust is in the order of 0.2–0.3mgkg−1.[1] In topsoils, Sb tends to be slightly enriched. Background concentrations of antimony in soils range between 0.3 and 8.6mgkg−1 (Table 1).[2,3] In general, they are below 1mgkg−1.[4]

Antimony toxicity and detoxification in plants. The excessive accumulation of Sb can be toxic to plants and can inhibit their growth. The levels of 5–10 mg kg −1 Sb in plant tissues have been suggested to be excessive or toxic (Kabata and Pendias, 2001). He (2007) reported that 5 mg kg −1 Sb was a tolerable concentration in plants.
