antimony 2012 plant accumulation.
Antimony level of 5-10 mg/kg in plants have been suggested to be toxic to plants 411(Herath et al., 2017;Kabata-Pendias, 2010), but the value of 5 mg/kg is considered to be 412 tolerable by some ...
The uptake of arsenic (As) species by Lycopersicum esculentum, growing under soilless culture conditions, was studied. A 4 × 3 × 2 factorial experiment was conducted with four As species (arsenite, arsenate, methylarsonate, and dimethylarsinate), three As concentrations (1, 2, and 5 mg L-1) and two tomato cultivars (Marmande and Muchamiel). The phytoavailability and phytotoxicity were ...
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.
Antimony is a toxic element whose concentration in soil and water has been rising due to anthropogenic activities. This study focuses on its accumulation in leaves of Dittrichia viscosa growing in soils of an abandoned Sb mine, and the effect on oxidant/antioxidant systems and photosynthetic efficiency. The results showed leaves to have a high Sb accumulation capacity.

One set of hydroponic trials was set up using four …
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 4h. More Sb was accumulated in iron plaque than in the plant, with ...
Antimony (Sb)-oxidizing bacteria play an important role in Sb biogeochemical cycle in soil, but the benefits of microbial oxidation for plants have not been well documented. The aim of this study was to explore the contribution of Sb(III)-oxidizing bacteria to alleviate the Sb toxicity in plants. The plant growth-promoting (PGP) characteristics of Sb(III)-oxidizing bacterium Bacillus sp. S3 ...

1. Introduction. Antimony (Sb) is a carcinogenic element for humans, which exists in soil mainly in the speciation of trivalent Sb [Sb(III)] and pentavalent Sb [Sb(V)] (Sh et al., 2012).In solution (pH 6.0), Sb(V) mainly exists as [Sb(OH) 6] −, while Sb(OH) 3 ° is the main Sb(III) form (Ren et al., 2014). Okkenhaug et al. (2012) confirmed that Sb(V) is stable even under reducing conditions ...
Foods produced on soils impacted by antimony (Sb) mining activities are a potential health risk due to plant uptake of the contaminant metalloids (Sb) and arsenic (As). Here we report for the first time the chemical speciation of Sb in soil and porewater of flooded paddy soil, impacted by active Sb mining, and its effect on uptake and speciation in rice plants (Oryza sativa L. cv Jiahua).
Biovolatilization and bioaccumulation capabilities of different elements by microscopic filamentous fungus Scopulariopsis brevicaulis were observed. Accumulation of As(III ), As(V), Se(IV ), Se(VI ), Sb(III ), Sb(V), Te(IV ), Te(VI ), Hg(II ), Tl(I) and Bi(III ) by S. brevicaulis was quantified by analysing the amount of elements in biomass of the fungus using ICP AAS .
This study was aimed to explore that effects of Sb on physiological parameters of Acorus calamus and the possibility of using A. calamus as a remediation plant. A. calamus potted experiments were conducted using different concentrations (0, 250, 500, 1000, and 2000 mg/kg) of antimony potassium tartrate (Sb3+) (marked as CK, T1, T2, T3, and T4, respectively) and potassium pyroantimonate (Sb5 ...
Used as a hardening agent in lead bullets, antimony (Sb) has become a major contaminant in shooting range soils of some countries including Switzerland. Soil contamination by Sb is also an environmental problem in countries with Sb-mining activities such as China and Bolivia. Because of its toxicity and relatively high mobility, there is concern over the risk of Sb transfer from contaminated ...

Another part of Sb can rapidly transport to plant shoots through the xylem vessel system related to the primary xylem in all vascular plants and secondary xylem (Vaculík et al., 2012). This process was generally considered as a crucial factor that affected metal or metalloid accumulation in plant shoots (Uraguchi et al., 2009).

1. Introduction. Arsenic (As) and Antimony (Sb) are metalloids that play a significant role in environmental pollution. The estimated crustal abundance of As is 1.8 mg/kg (Taylor, 1964) while Sb is between 0.2 and 0.3 mg/kg (Huang et al., 2012; Cai et al., 2016).In unpolluted soils Sb ranges from <0.3 to 8.4 mg/kg and As from 5 to 6 mg/kg (Zeng et al., 2015).

INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure antimony is refined.

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).
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.
Elevated concentrations in nine native plant species were reported (109-4029 mg/kg); Sb-levels in the soil was between 527 and 11798 mg/kg. The corresponding calculated BSAFs ranged from 0.02 to 0.87. The accumulation of antimony in plants growing in two Iranian mining areas (Moghanlo, Patyar) was studied by Hajiani et al. (2015).

Mar 24, 2020· Antimony (Sb) contamination has become an increasing environmental concern. A pot experiment was conducted to investigate the effects of biochar application on the maize seedling grown in Sb-contaminated soil. Two Sb levels (0, 200 mg kg−1) and three biochar rates (0, 1%, 4%) were included, giving a combination of six treatments. The results showed that exposure to Sb without …
Antimony (Sb) is locally found at potentially toxic concentrations in mineralized soils, usually together with arsenic (As). However, local adaptation of plant populations to Sb toxicity has never been shown thus far. Here we compared Sb tolerance and accumulation between a non-metallicolous (NM) population of Salvia spinosa, and a con-specific metallicolous (M) population from a strongly Sb ...
Methylated As species in plants have been suggested to originate from the soil and microorganisms in the plant rhizosphere ( Lomax et al. 2012, Zangi and Filella 2012, Jia et al. 2013). Little is known about the mechanisms underlying the uptake and transport of methylated As.
