Abstract. The distribution, bioavailability, and accumulation of antimony (Sb) at the interface of rhizospheric soils and indigenous plants from a large Sb mining/smelting area in Southwest China were explored. Results showed that the local soil was severely polluted by Sb, and the aluminum magnesium silicate minerals and the carbonate fraction ...

Evidence is found for the development of a strong oxidative stress induced by Sb, with there being a clear imbalance in the content of the compounds that constitute the AsA/GSH cycle. The alterations induced by the toxicity of antimony (Sb) in the roots and leaves of sunflower plants were determined. The plants were grown hydroponically with …

plant growing near an Sb smelter contained Sb concentrations as high as 121.4 mg kg−1 Sb in its leaves (He 2007). Although Sb is a non-essential element for plants, it can be readily taken up by plants (Ainsworth et al. 1991). Levels of 5–10 mg kg−1 of Sb in plant tissue have being reported as phytotoxic (Kabata-Pendias & Pendias 2001).

Antimony (Sb) is a non-essential element for living organisms as it has no role in biological functions. It can be a potentially toxic element to plants, humans and animals beyond the tolerable limits (Feng et al., 2013a; Zhang et al., 2018). In the Earth's crust, Sb exists in the form of sulfide ores; stibnite (Sb 2 S 3) and valentinite (Sb 2 ...

Antimony (Sb) is a naturally occurring trace element in the earth's crust, and it is a non-essential element for life processes. The average concentration of Sb in soil is about 0.48 mg kg −1, and soil levels of Sb are much higher in antimony-processing sites and hazardous waste sites (ATSDR 1992).There is much concern regarding Sb pollution …

Plant roots absorb and accumulate most of the Sb, and the cell wall and cytoplasm play an essential part in Sb accumulation in plants . Sb is absorbed and transported by plant tissues via the plastid extracellular or cytoplasmic pathway, where the cell membranes absorb Sb(III) via water channel proteins [ 8 ].
