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 …
They also play a vital role in immobilizing toxic-element Sb through redox reactions, adsorption and precipitation processes (Fan et al., 2014, Guo et al., 2009, Mittal et al., 2013). In addition, many batch and kinetic experiments have studied the feasibility of the adsorption reaction of Sb on iron oxides under controlled laboratory conditions.
Root exudates mediates the interaction between plants and other organisms. Different biological factors, intrinsic to the plant, also affect root exudation, including the genotype and the age of the plant. The type and amounts of the compounds synthesized and released by roots are under the plant's genetic control.
Antimony in excess is reported to have toxic effects on plants (Feng et al., 2013; Natasha et al., 2019) as shown in Fig. 1. The intensity of toxicity mostly depends on speciation of Sb and ...
presented in plants at rather low concentrations are non-necessary impurities that do not play an essential role in the biochemical processes in the plants. Antimony (Sb) is a metalloid found in more than 100 minerals (Draggan 2008). Various industrial applications of Sb have led to an increasing release of Sb into the
We evaluated the direct release to the environment of a number of potentially toxic elements (PTEs) from various processing nodes at Xikuangshan Antimony Mine in Hunan Province, China. Sampling wastewater, processing dust, and solid waste and characterizing PTE content (major elements Sb, As, Zn, and associated Hg, Pb, and Cd) …
Non-toxic, no-waste process technology for antimony recovery. Antimony plays an important role in the global economy. Pioneering eco-friendly process technology will help recover antimony from various materials and processes, enhancing the competitiveness of numerous industries.
In addition to its principal role in the control of plant growth and development, the cell wall participates in the acclimation processes of plants exposed to diverse abiotic stresses. One such stress is salt exposure, where the cell wall acts as a barrier to prevent the influx of Na + and Cl − ions into the protoplast, thus maintaining cell ...
Abstract. Removal of heavy metal ions from wastewater is of prime importance for a clean environment and human health. Different reported methods were devoted to heavy metal ions removal from ...
Effect of Si and Sb on plant growth and biomass. Silicon is known to play a key role in alleviating plant abiotic stress (Adrees et al. 2015; Bhat et al. 2019; Vaculík et al. 2020).Many studies have previously shown that the Si can enhance plant biomass and growth of metal stressed plants such as barley, rice, maize etc. (Vaculík et al. 2009; …
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 …
Laboratory experiments in which earthworms were exposed to four different Sb spiked agricultural soils (acidic, neutral, alkaline and calcareous alkaline soil) were conducted in a climate-controlled room. The study surveyed the toxicity of Sb to the Eisenia fetida at the individual (mortality, growth inhibition, Sb accumulation), physiological …
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. …
Pollution of antimony (Sb) raises a serious environmental problem. Although this non-essential element can be taken up by roots and accumulated in plant tissues in relatively high concentrations, there is still lack of knowledge about the effect of Sb on biochemical and metabolic processes in plants …
Antimony has no known biological use. Role in Life Processes. No known benefit in life processes. Percentage Amount in the Human Body: 0.000003%. Sources. Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing ...
Take the supernatant and use the molybdenum antimony ... Chinese fir seedlings inoculated with different strains exhibited significantly different increases in plant height (p < 0.05), which was ...
Aside from human beings and plants, a variety of invertebrates and aquatic species are also affected by the toxicity of Sb species. In freshwater systems, the presence of antimony chloride (SbCl 3) inhibits the respiration of carp (Chen and Yang, 2007), whereas exposure to ~2 mg L-1 Sb is lethal to shrimp (Yang, 2014).
Brassinosteroids (BRs) are a group of steroidal phytohormone that plays an essential role in regulating various chemical and physiological processes involved in plant growth and development.
Brassinosteroids (BRs) play a crucial role in improving plant resistance to various environmental stresses. In this study, we aimed to explore the potential role of BRs in protecting plants from antimony (Sb) toxicity. In the in vitro agar-plate culture experiments, the level changes of BR in wide-type plants and BR biosynthesis mutant …
Antimony (Sb) is a naturally occurring trace element in the earth's crust, and it is a non-essential element for life processes. The average concentration of Sb in soil is …
The availability of antimony in the environment can be regulated by a host of different technological processes, including but not limited to, coagulation, membrane …
Semantic Scholar extracted view of "Effects of different forms of antimony on rice during the period of germination and growth and antimony concentration in rice tissue" by M. ... Salicylic acid (SA) plays a crucial role in plant growth, development and stress resistance. ... Soil Processes and the Behavior of Metals (B. Alloway). The Origins ...
Accordingly, plants can supply additional substrates through C investment for microbes to produce phosphatases (Fig. S3), enabling the system to recycle more P. Together, slope position mediated P co-utilization by regulating a series of rhizosphere processes, with resource imbalances for plants and microbes being pivotal roles in …
Other ways by which plants can resist toxic concentrations of Sb rely on other biological responses. Plants react to Sb toxicity in different ways, from the building up of specific …
Metagenome-assembled genomes (MAGs) indicated that the keystone taxa in the revegetated tailing may use both organic and inorganic energy sources (e.g., sulfur, arsenic, and antimony). They could also facilitate plant growth since a number of plant-growth-promoting genes, including phosphorus solubilization and siderophore production …
Aims 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. Methods The plant growth-promoting (PGP) …
The last stage of the process is the final caustic clean, which removes any trace impurity of elements such as antimony, calcium, magnesium, and zinc that may have passed through from the previous processes. The metal is pumped from the debismuthizing area to the final pots where it is held at about 500 °C.

Fig. 1 shows the Sb removal performance under different S 0 dosages. The concentration of Sb(V) decreased over time in all the microcosms (Fig. 1 (a)).By the end of the experiment, the Sb(V) concentration decreased by 21.7% in the microcosm bottle with no addition of S 0.This was because the endogenous decay of biomass provides electron …
