Dittrichia viscosa plants were grown hydroponically with different concentrations of Sb. There was preferential accumulation of Sb in roots. Fe and Cu decreased, while Mn decreased in roots but not in leaves. Chlorophyll content declined, but the carotenoid content increased, and photosynthetic efficiency was unaltered. O2 − generation increased slightly, while lipid peroxidation increased ...

In addition, H2O2 treatment did not produce any significant effects on antimony and magnesium accumulation in the leaves or the syconium of F. deltoidea plants. The results show that the F. deltoidea plant has strong antidiabetic properties and its α-glucosidase activity increased in treated plants compared to standard acarbose.
SPMP developed the concept of a modern antimony roasting and gold plant in 2012, to be the first western-world minor metal primary smelter in nearly 40 years. The SPMP Smelter converts primary sulphide concentrates, produced in mines from almost every region around the world into finished antimony, a strategic minor metal.
Potential Risk of Arsenic and Antimony Accumulation by Medicinal Plants Naturally Growing on Old Mining Sites. ... 29 October 2012 / Accepted: ... In total, seven different plant …
12%For plants, Sb is a non-essential element and accumulation reaching to 5–10 mg/kg in plant tissue can even be phytotoxic (Feng et al. 2013; Okkenhaug et al. 2012; Wu et al. 2019). Reduced growth and enhanced leaf chlorosis as a consequence of Sb have been observed in some agricultural plants, such as sunflower, wheat, rice or maize (He and ...
The results showed that the distance from the street decreased the accumulation of many potentially toxic elements. Furthermore, the human health risk was estimated, revealing that greater danger was associated with the accumulation of antimony. Concentration of other elements in the leaf tissues were within previously reported thresholds.
This may increase plant uptake of As and hence pose a risk to human health. Arsenic and antimony (Sb) often co-occur in contaminated soils; however, little is known about the interactions between As and Sb with PO 4 3-on their bioavailability, accumulation, and toxicity in plants.
In the present study, Pteris cretica 'Albo-Lineata' (PC), Pteris fauriei (PF), Humata tyermanii Moore (HT), and Pteris ensiformis Burm (PE), were selected to explore additional plant materials for the phytoremediation of As and Sb co-contamination. To some extent, the addition of As and Sb enhanced the growth of HT, PE, and PF. Conversely, the addition of As and Sb negatively affected the ...
Effect of interactions between boron (B) and antimony on the uptake and accumulation by rice (Oryza sativa L.) seedling was investigated in solution culture. The results showed that Sb(III) and Sb(V) could inhibit rice growth and Sb(III) was more toxic than Sb(V).
Potential Risk of Arsenic and Antimony Accumulation by Medicinal Plants Naturally Growing on Old Mining Sites. Water, Air, & Soil Pollution, 2013. Lubomir Jurkovic. Marek Vaculík.
Antimony (Sb), one of the toxic elements with no known biological function, is of great environmental concern because it is considered as priority contaminant by USEPA and EU 1,2.It is …
It was found that some of the medicinal plants accumulate increased amounts of toxic elements like Cd or Pb. Less is known about the accumulation of other hazardous elements like arsenic (As) and antimony (Sb) in these species. The present paper investigated selected medicinal plants naturally growing on old mining sites in Slovakia, Central Europe, contaminated by As and Sb. Both …
The antimony processing plant is located in the north of XKS Antimony Mine, Hunan Province. It covers an area of about 18,000 m 2 and has a beneficiation scale of 1500 t/d (ton/day). The beneficiation ore is of single antimony sulfide ore, a kind of low temperature hydrothermal filling deposit.
Accumulation of antimony and other potentially toxic elements in plants around a former antimony mine located in the Ribes Valley (Eastern Pyrenees) J. Bech, I. Corrales, P. Tume, J. Barceló, P. Duran, N. Roca, C. Poschenrieder
Antimony mining in this area began in 1897, and the present annual production of Sb is 55,000 tons of ore and 40,000 tons of Sb products (Wang et al., 2011).
12%Effect of antimony on plant growth. The present study compared the Sb accumulation potential and the different biochemical responses to medium (5 mg L −1) and high (20 mg L −1) levels of Sb, using one As—hyperaccumulating fern (PCA) and three non-As-hyperaccumulating ferns (CYD, CYF and MH), with no Sb addition (0 mg L −1) as the control.Only …
Antimony 150 50 74.0 0.4 concentration in the growth media and plant tissues were determined by a graphite 50 150 24.2 4.1 furnace atomic absorption spectrophotometer (GFAAS, Varian 240Z, Walnut Creek, 0 200 1.1 0.5 CA).
Production of transplastomic plants. In an attempt to improve accumulation and stability of the VP6 protein in tobacco chloroplasts, four new gene constructs with alterations of the 5′‐UTR or the 5′ end of the VP6 coding region, compared to the constructs used by Birch‐Machin et al., have been introduced into the transformation vector pZSloxP (Zhou et al., 2008) for insertion into the ...
Antimony (Sb) distribution and accumulation in plants in Xikuangshan Sb deposit area, the only one super-large Sb deposit in the world, Hunan, China were investigated.
The accumulation of Zn, Cu, Cd and Pb in the shoots of all nine plant species remained below the Swiss tolerance values for fodder plants (150 mg kg(-1) Zn, 15-35 mg kg(-1) Cu, 40 mg kg(-1) Pb, and 1 mg kg(-1) Cd DW), with the only exception of Pb in Chenopodium album shoots which reached a concentration of 62 mg kg(-1) DW.
Animal experiments in rats, mice, hamsters and dogs also revealed accumulation of antimony in the lungs, the presence of antimony in the erythrocytes and its distribution in the bones, liver, kidney, spleen, pancreas, thyroid and gastrointestinal tract after inhalation exposure to antimony trioxide, antimony pentachloride or an antimony ...
Plant ability to accumulate antimony was estimated by use of plant accumulation coefficients (PAC). Seasonal (spring vs. autumn) effects on the antimony content in the plant species. Cytisus striatus from Mari Rosa mine presented antimony excluder characteristics, whereas Dittrichia viscosa specimens growing in San Antonio mine showed a ...
Antimony (Sb) accumulation in rice is a potential threat to human health, but its uptake mechanisms are unclear. A hydroponic experiment was conducted to investigate uptake, translocation, speciation and subcellular distribution of Sb in rice plants exposed to antimonite (SbIII) and antimonate (SbV) at 0.2, 1.0 or 5.0 mg/L for 4 h.More Sb was accumulated in iron plaque than in the plant, with ...
