Antimony uptake, translocation and speciation in rice

11-01-2022 · 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, or mg/L for 4h.

Arsenic and antimony in water and wastewater:

15/03/2022· Only in the last decade antimony had gain particular interest probably as a consequence of its toxic and carcinogenic nature as well as the elevated concentrations in the vicinity of smelters, chemical plants, and mining and mineralized areas (Tighe et al., 2022). Treatment processes for Sb and As removal are however close due to the chemical similarity of these elements.

Jianjun Mei, Jiangsu Key Laboratory for Carbon-Based Functional Materials and Devices, Institute of Functional Nano and Soft Materials (FUNSOM), Joint International Research Laboratory of Carbon-Based Functional Materials and Devices, Soochow University, 199 Ren'ai Road,


Increased arsenic, bromine and antimony concentrations are attributed to seepage of groundwater originating in the nearby Tokaanu-Waihi geothermal field, and are found in particular on the western side of the wetland. Due to its sensitivity, INAA was useful to determine the subtle changes in Br and Sb concentrations, which could not be detected by XRF. Analysis of the ashed residue by INAA

C4 plants | Biological Principles

What Biol 1510 students need to remember about C4 is that these plants have added a CO2 concentration mechanism to feed rubisco and the Calvin cycle; the mechanism uses PEP carboxylase to initially make a 4-carbon compound, that then releases CO2 to rubisco in leaf cells that are exposed to little oxygen. While this mechanism reduces the oxygenase activity of rubisco, it has an extra energy

Antimony - Element information, properties and

Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as most famous user was the temptress Jezebel whose exploits are

$100m antimony plant set for June launch - Oman Observer

28-03-2022 · The front end of the plant, comprising of the concentrate handling shed and concentrate dryer, is complete and ready for cold commissioning," said Tri-Star Resources, a 40 per cent shareholder, in a statement. "The plant is due to produce its first antimony metal in June 2022.

Original article

Tissue concentrations of antimony in lung, liver, and kidney tissue from a group of deceased smelter workers from northern Sweden have been compared with those of a group of persons without occupational exposure from a nearby area. Neutron activation analysis was used to determine the antimony concentration of lung tissue from exposed workers; these concentrations were 12-fold

Accumulation and transport of antimony and

We found that the common climbing plant Kudzu (Pueraria lobata) is suitable for phyto-stabilisation of antimony-bearing tailings, while tiger grass (Thysanolaena maxima) was able to extract antimony and arsenic from contaminated soils. Antimony (Sb) pollution is a major environmental issue in China. Many historical abandoned tailings have released high concentrations of Sb and its associated

A comparative study of antimony accumulation in

17/06/2022· Antimony occurs locally at high concentrations in some mineralized soils. 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 –287 and –49 mg/kg, respectively. In both areas, foliar Sb concentrations

A Global Garden: Plants Storing Carbon - NASA

 · December 1 - 31, 2022 PNG. Plants breathe. They take carbon dioxide from the atmosphere and turn it into the sugars that become leaves, stems, roots, and woody trunks. What carbon dioxide they don't use, they exhale, releasing the leftover gas with oxygen. And after plants die, they decay, releasing the carbon to the atmosphere.
