the establishment of sustainable plant communities (Mishra, Singh & Arora., 2017). Many rhizospheric microorganisms, particularly some plant-growth-promoting rhizosphere bacteria, can increase biomass production and/or decrease the accumulation of heavy metal in plants (Mishra, Singh & Arora., 2017; Lebeau, Braud & Jezequel, 2008).


12%Arsenic (As), antimony (Sb), and bismuth (Bi) are metalloids that share similar chemical properties, the objective of this study was to characterize the uptake and accumulation of these metalloids by plants colonized on heavy contaminated sites in an old Sb mine. Sixty-five plant samples from seven species as well as the associated soil samples were collected at …


12%Field samples and a 9-week glasshouse growth trial were used to investigate the accumulation of mining derived arsenic (As) and antimony (Sb) in vegetable crops growing on the Macleay River Floodplain in Northern New South Wales, Australia. The soils were also extracted using EDTA to assess the potential for this extractant to be used as a predictor of As and Sb …

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 ...


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 ...


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.

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).


Very little is known about behavior of antimony in plants. In this study, we analyzed the soil and vegetation of two mining areas in Iran, Patyar, and Moghanlo. Total Sb concentrations in soil were 358-3482 mg/kg in Moghanlo and 284-886 mg/kg in Patyar. Corresponding Sb concentrations in plant shoots were 0.8-287 and 1.3-49 mg/kg, respectively.

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.

Antimony enters the environment during the mining and processing of antimony-containing ores and in the production of antimony metal, alloys, antimony oxide, and combinations of antimony with other substances (Grund et al. 2012; Li et al. 2011). Antimony was mined in the United States; however, the last mine closed in 2001 (HSDB 2005a).


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 excessive accumulation of Sb can be toxic to plants and can inhibit their growth. The levels of 5–10 mg kg −1 Sb in plant tissues have been suggested to be excessive or toxic (Kabata and Pendias, 2001). He (2007) reported that 5 mg kg −1 Sb was a tolerable concentration in plants.

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 …


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.


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. Results show that soils were severely polluted with the average Sb concentrations up to 5949.20 mg kg − 1 .


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.

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.

Antimony transfer factors from soil to rice grain (He and Yang, 1999), a major staple food worldwide, or vegetables (Wilson et al., 2014) are very low. However, in severely polluted soils with a high fraction of soluble, mobile Sb enhanced accumulation in edible plant parts is to be expected (He and Yang, 1999).


In A. ageratum, the distribution and accumulation of antimony in the plant parts, as well as the translocation of the element from the roots to the epigeal parts, are not homogeneous (Table 2, Table 3, Table 4).Sometimes the roots are the target part, with a high concentration coefficient (as at MD 2), but more often the species accumulates Sb in the basal leaves and inflorescences (when present).
