Soil antimony pollution and plant growth stage affect the …
A total of 4512 rhizobacteria were isolated at three stages of plant growth from Achillea ageratum colonizing a polluted site with an antimony concentration gradient. For 222 of these isolates auxin production (aux +) was verified in vitro.The percentage of aux + isolates increased with soil antimony concentration, as well as with plant growth …
Mobility of antimony in soil and its availability to plants
The antimony concentrations in these soils are up to 500 mg/kg. Antimony transfer into 19 vegetable and crop species was investigated. In grain and other storage organs up to 0.09 mg Sb/kg were found, whereas maximum antimony concentrations in shoots and leaves were determined to be 0.34 mg Sb/kg and 2.2 mg Sb/kg, respectively.

Antimony accumulation and antioxidative responses in four fern plants
Accumulation of antimony. Antimony concentrations in the fronds and roots of all plants increased with Sb addition, with more Sb accumulated in the roots than in the fronds (Fig. 1).At the high rate of Sb addition, the average Sb concentration in the roots was the highest in fern PCA, at 358 mg kg −1, followed by 224 mg kg −1 in fern CYF, 124 mg …
A Review on Pyrometallurgical Extraction of Antimony from …
Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology …
Antimony toxicity in soils and plants, and mechanisms of its
Antimony recognition in tissue and cellular distribution and localization is still in its early stages, so more research is needed to better understand how Sb functions in plants. 6. Impact of Sb on plant growth and performance. Antimony in excess is reported to have toxic effects on plants (Feng et al., 2013, Natasha et al., 2019) as shown in ...
