Antimony (Sb) is a toxic metalloid that has been listed as a priority pollutant. The environmental impacts of Sb have recently attracted attention, but its phytotoxicity and biological transformation remain poorly understood. In this study, Sb speciation and transformation in plant roots was quantified by Sb -edge X-ray absorption spectroscopy.
Environmental context Phytoremediation requires an understanding of bioconcentration and translocation processes that determine behaviour and fate of potentially toxic elements. We studied the distribution of antimony and arsenic in terrestrial and aquatic soil-plant systems in an antimony ore zone. We found that the common …

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 (Remans …
Antimony (Sb) is a naturally occurring metalloid element. It can exist in a variety of oxidation states (−III, 0, III, V), but is mainly found in two oxidation states (III and V) in environmental, biological and geochemical samples [].The abundance of Sb in the Earth's crust is in the order of 0.2–0.3 mg kg −1 [].The concentration of Sb in soils is …

Antimony levels in plants. Only a few studies have focused on Sb pollution in Chinese plants, so, we collected data from plants in some of the mining areas (Table 4). Elevated Sb concentrations were found in plants growing in the Xikuangshan mine area. ... The Sb concentrations in six plants collected from Daye iron mine in Huangshi City, ...
A major part of this antimony is bio available as indicated by the higher total Sb concentrations (108–4029 mg. kg −1) in the sampled plants from the mining area. The bioavailable fraction of antimony in the soil is estimated through citric acid extraction ( Okkenhaug et al., 2011 ).
Mean metalloid creek rhizome sediment concentrations were 777 115g g-1 Sb and 60 6g g-1 As, with water concentrations at 381 23g L-1 Sb and 46 2g L-1 As. Antimony and As were significantly ...
The concentration of antimony extracted was compared with the total antimony content in the plant material measured by HG-AFS after focused microwave-acidic digestion using HNO3 and H2O2.
The concentrations of antimony in crops are also higher. The average enrichment factors (concentration in plant/concentration in soil) for rice root, stem-leave and rice seed are 0.144, 0.012 and 0.0037, respectively. In the antimony mine areas, some health-related diseases exist due to the antimony pollution.

Concentration of Sb in roots was increased upon the addition of Sb both in WT and mutant plants (Figure 5c). Antimony concentration was higher in roots than in shoots, and Sb concentration in mutant plants was nearly a two-fold decrease when compared to WT plants. The root Sb concentration was nearly identical in the Sb + Si …

Antimony uptake varies widely among plant species, growing sites, and underlying substrate conditions ( Table 1 ). Most commonly, the highest plant Sb concentrations occur in mining areas where the concentration of Sb in the soil is …
Plant-to-plant differences in Sb absorption. Antimony uptake varies widely among plant species, growing sites, and underlying substrate conditions (Table 1). Most commonly, the highest plant Sb concentrations occur in mining areas where the concentration of Sb in the soil is appreciably high (sometimes more than 1000 mg Sb kg …
At increased concentration in edible plant parts or medicinal herbs it may pose health risks to humans and livestock. Although most of Sb is stored in root tissues, …
and antimony. The total thujone content of preban absinthe was found to range between 0.5 and 48.3 mg/L, with an average concentration of 25.4 ( 20.3 mg/L and a median concentration of 33.3 mg/L. The authors conclude that the thujone concentration of preban absinthe was generally overestimated in the past.
Antimony toxicity in plants not only depends on the uptake and potential concentration of Sb in plants but also on its speciation inside plants. The extent of Sb …
Antimony (Sb) is introduced into soils, sediments, and aquatic environments from various sources such as weathering of sulfide ores, leaching of mining wastes, and anthropogenic activities. High Sb concentrations are toxic to ecosystems and potentially to public health via the accumulation in food chain. ... Plant species: Concentration or ...
