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 …

Antimony (Sb) is a non-essential element for plants, animals, and humans. With increased anthropogenic inputs from mining and industrial activities, ore processing, vehicle emissions, and shooting activities, elevated Sb levels in the environment have become a growing concern.
It is considered that Sb concentration in soils greater than 150 mg/kg causes damage to plants (Feng et al., 2020).It affects all plant processes ranging from germination, growth, development, photosynthesis, and induced reactive oxygen species (ROS) production; all these changes induce a serious reduction in plant growth …
