Arsenic can be biomethylated to form a variety of organic arsenicals differing in toxicity and environmental mobility. Trivalent methylarsenite (MAs(III)) produced in the methylation process is more toxic than inorganic arsenite (As(III)). MAs(III) …
Thailand is about 3.5 times bigger than Bangladesh. Bangladesh is approximately 148,460 sq km, while Thailand is approximately 513,120 sq km, making Thailand 246% larger than Bangladesh. Meanwhile, the population of Bangladesh is ~162.7 million people (93.7 million fewer people live in Thailand). This to-scale map shows a size comparison of ...
Zirconium oxide (ZrO2)-carbon nanofibers (ZCN) were fabricated and batch experiments were used to determine antimonite (Sb(III)) and antimonate (Sb(V)) adsorption isotherms and kinetics. ZCN have a maximum Sb(III) and Sb(V) adsorption capacity of 70.83 and 57.17 mg/g, respectively. The adsorption pr …
Third generation of infrared imagers demand performances for higher detectivity, higher operating temperature, higher resolution, and multi-color detection all accomplished with better yield and lower manufacturing costs. Antimonide-based gap-engineered Type-II superlattices (T2SLs) material system is considered as a potential alternative for Mercury- Cadmium-Telluride …
Aqueous Sb speciation was dominated by antimonate, while antimonite concentrations were low, further supporting our findings of much higher reactivity of Sb(III) than Sb(V) toward peat surfaces. Insufficient residence time for efficient reduction of antimonate to antimonite currently hinders higher Sb removal in the studied peatland. Overall ...
The Xikuangshan Sb mine (designated as 'the World Antimony Capital') is the world largest Sb deposit with approximately 120 years of mining history. The dumping of large amounts of Sb-containing mining waste may pose natural selection on indigenous microbiota and enrich Sb-metabolizing microorganisms (Wang et al. 2011; Wang, Zhang and He 2018 ).
Antimonite (Sb(III)) oxidation can decrease Sb toxicity, which contributes to the bioremediation of Sb contamination. Bacteria can oxidize Sb(III), but the current knowledge regarding Sb(III)-oxidizing bacteria (SbOB) is limited to pure culture studies, thus underestimating the diversity of SbOB. In this study, Sb(III)-oxidizing microcosms were ...
Definition: (n.) A compound of antimonious acid and a base or basic radical. (n.) Stibnite. Example Sentences: (1) Extrapolation of the amount of FSBA required to inactivate the protein indicated that 1 mol of FSBA was sufficient to inhibit the activity of 1 mol of ArsA protein in the absence of substrates, while only 0.5 mol was required in the presence of the anionic substrate antimonite.
After 14 d exposure, P. cretica took up 1.4-2.8 times more SbIII than SbV. Since P. cretica was unable to translocate Sb, its roots accumulated >97% Sb with the highest at 7965 mg/kg. In both SbIII and SbV treatments, SbIII was the predominant species in P. cretica, with 90- and 46- SbIII in the roots.
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.
The total length of the border between the land area and the sea, including the country's islands. total land area. 130 170 km². 653 508 km². The country's total land area (excluding inland and sea waters). To get a better idea of how large the country is, you can compare it with a soccer field, which has 0.007km².
The IMF had indicated Bangladesh's economy has grown to $322 billion by 2021. Today, an average Bangladeshi citizen is much wealthier compared to Pakistan. This month, it was reported that Bangladesh's GDP per capita had grown by 9% over the past year to $2,227. Pakistan's per capita income is $1,543. In 1971, Pakistan was 70% richer than ...

Oxidation of organoarsenicals and antimonite by a novel flavin monooxygenase widely present in soil bacteria. ... produced in the methylation process is more toxic than inorganic arsenite (As(III)). MAs(III) also serves as a primitive antibiotic and, consequently, some environmental microorganisms have evolved mechanisms to detoxify MAs(III). ...
