Antimony (Sb) is a dangerous heavy metal (HM) that poses a serious threat to the health of plants, animals, and humans Leaching from mining wastes and Antimony Speciation transformation Toxicity Plants Absorption 1 Introduction Anthropogenic activities, such as metal (metalloid) mining, smelting and the The uptake and detoxification of antimony by plants: A
We reviewed the available literature and found that Sb is generally taken up by terrestrial plants in proportion to the Antimony (Sb) is a nonessential element for plants, animals, and humans With increased anthropogenic inputs from mining and industrial activities, ore Antimony toxicity in soils and plants, and mechanisms of its
On an average, Sb concentration in soil is 02 mg/kg ( Vodyanitskii, 2016 ) Antimony is a chalcophile element which is present in a number of ores and minerals Antimony can damage plants, including growth retardation, inhibition of photosynthesis, decreases in the uptake of certain essential elements and decreases in The uptake and detoxification of antimony by plants: A
Abstract In a historical mining area residual material has been filled on land and these locations are used today as agricultural soils or house gardens The antimony Keywords: antimony; growth; health risks; photosynthesis; remediation Antimony (Sb) is a dangerous heavy metal (HM) that poses a serious threat to the Toxic effects of antimony in plants: Reasons and remediation
1 Antimony general aspects Antimony comes under group 15 of the periodic table with ground state electronic configuration [Kr]4d 10 5s 2 5p 3 121 Sb The presence of antimony (Sb) in high concentrations in the environment is recognized as an emerging problem worldwide The toxicity of Sb in plant tissues is known; however, new methods of plant Plants Free FullText Silicon Actuates Poplar Calli
31 Antimony concentrations in soil and in different plant parts and effects of Sb on the biomass of wheat seedlings Concentrations of Sb and other macro and trace elements in the rhizosphere soil and in roots and leaves of wheat seedlings are presented in Tables 1 and 2An increase of Sb in soil resulted in its accumulation in roots Antimony toxicity and detoxification in plants 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 The uptake and detoxification of antimony by plants: A review
Danjiangkou Reservoir is the water source of the midroute of the SouthtoNorth Water Transfer Project The source, distribution and potential risk of antimony in its water and sediments are rarely reported In this study, symmetrical investigation results demonstrated that the concentration of antimony in the Han subreservoir and water in High concentrations of antimony have been reported in soil, vegetation, herbivorous and insectivorous mammals at sites around an antimony smelter (Ainsworth et al, 1990a, Ainsworth et al, 1990b) Antimony is nonessential to plants, but can be readily taken up by roots from soils when in soluble formsEffects of different forms of antimony on rice during the period of
The final factor involves variations in the concentrations of coexisting ions in soils, such as phosphorus (P) and calcium (Ca) (Fig 1)The addition of phosphate amendments was observed to effectively mobilise Sb in Sbcontaminated soils (Spuller et al, 2007), and P may facilitate plant uptake of Sb via competitive adsorption to soil Relationship between total Sb concentrations of fieldcontaminated soils and Sb in plants grown on these soils, based on published data [10,11,2224,39,41,53,56,7074] The points represent(PDF) Antimony in the soil Plant system A review
Antimony in the soil–plant system–areview Table 1 Published values of Sb concentrations in the environment Medium Source of pollution Concentration (mgkg−1, Reference unless given otherwise) Igneous rocks 01–1 [57] Sedimentary rocks 005–15 [55] Soil background 03–23 [2] Seawater 00002 [5]Some plant species, notably Achillea ageratum, Plantago lanceolata, and Silene vulgaris, accumulate antimony readily For example, according to the results of the aforementioned research, plant concentration can exceed 440 ppm, depending on the plant species and the uptake mechanismAvailability, Toxicology and Medical Significance of Antimony
In grain and other storage organs up to 009 mg Sb/kg were found, whereas maximum antimony concentrations in shoots and leaves were determined to be 034 mg Sb/kg and 22 mg Sb/kg, respectively Despite the high antimony contamination of the soils, concentrations in the investigated plants in general corresponded to concentrations 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 )Antimony, a pollutant of emerging concern: A review on industrial
This study indicated that the threshold concentration of antimony for radish and rape plants was 10 mg/L Effect of antimony on the growth of radish and rape seeds The effects of different antimony concentrations on the elongation of radish and rape seed roots were shown in Fig 2Antimony is one of the most exploited elements with the global annual production of 14 × 10 5 tons causing its elevated concentration in water, soil and sediments especially near mining and smelting areas (Guo et al, 2014)For example, He et al (2012) reported high concentration of Sb in mining and smelting area of China They Biogeochemistry of antimony in soilplant system: Ecotoxicology
Antimony concentrations as high as 720 μg/L were found in stream waters in the Kantishna Hills mining district, Denali National Park and Preserve in Alaska (USA) [ 15 ] High Sb levels (up to 6384 μg/L) were found in rivers around the world’s largest Sb mine at Xikuangshan area of Hunan Province (China), and the Sb content in sediments ranged Antimony (Sb) is a dangerous heavy metal (HM) that poses a serious threat to the health of plants, animals, and humans Leaching from mining wastes and weathering of sulfide ores are the major ways of introducing Sb into our soils and aquatic environments Crops grown on Sbcontaminated soils are a Toxic effects of antimony in plants: Reasons and remediation
Antimony (Sb) is a dangerous heavy metal (HM) that poses a serious threat to the health of plants, animals, and humans Leaching from mining wastes and weathering of sulfide ores are the majorLikewise, rice plants grown in Sb mine areas were reported to accumulate high concentrations of Sb, with levels reaching up to 225 mg/kg in the roots and 579 mg/kg in the seeds (Ren et al 2014) Therefore, it is essential to develop mitigation strategies that can protect plants and organisms from Sb and reduce the risk of Sb Mitigating Antimony Toxicity in Rice (Oryza Sativa L) Through
Antimony Concentration in Rice and Antimony Speciation in Rice Plants The roots, stems, leaves, and grain of rice were freeze dried with a FD5series freeze dryer (SIM, United States), and 100 mg of each sample was transferred to Maximum soil and plant concentrations on a dry weight basis of 1489 mg kg −1 and 336 mg kg −1, respectively, were found, compared to background levels of < 1 mg kg −1 Field exposure of grass in pots of uncontaminated soil and a laboratory experiment using soils from near the smelter suggested that the antimony in vegetation was largely Distribution of antimony in contaminated grassland: 1—
