Mineralization and historical mining of stibnite (antimony sulfide), tungsten, gold, silver, and mercury in the headwaters of the East Fork of the South Fork Salmon River (EFSFSR) near the former town of Stibnite in central Idaho resulted in water-quality impairments related to mercury, antimony, and arsenic. Additionally, mining-related …

Arsenic and antimony levels in geothermal groundwater (Izmir, Turkey) were reported in the ranges 0.7–170 μg/L and 0.06–26 μg/L, respectively (Aksoy et al., 2009).

Co-contamination of soil with arsenic (As) and antimony (Sb) poses a serious risk to the environment and human health. This study used Fe-functionalized biochar (FBC) for the remediation of an As-Sb co-contaminated soil. The addition of FBC simultaneously decreased the bioavailability of As/Sb by facilitating the transformation of mobile As and ...

Arsenic (As) and antimony (Sb) speciation and mobility in river systems can be influenced by the redox conditions of benthic and hyporheic zone sediments. However, our understanding of how …

Arsenic, antimony, and bismuth each exist in several allotropic forms. There are three crystalline forms of arsenic, of which the ordinary, gray, metallic, rhombohedral α-form is the stablest at room temperature. Antimony exists in five forms in addition to the ordinary α-form. The chapter describes the physical properties of the α ...

It Is Time to Explore Unique Mechanisms for Microbial Antimony Conversion Rather Than Relying on Analogies with Arsenic Bioconversion Environ Sci Technol . 2023 Oct 24;57(42):15780-15781. doi: 10.1021/acs.est.3c08029.

Arsenic and antimony contamination is found at the Pezinok mining site in the southwest of the Slovak Republic. Investigation of this site included sampling and analysis of water, mineralogical analyses, sequential extraction, in addition to flow and geochemical modeling. The highest dissolved arsenic concentrations correspond to …

Jarosite, a common mineral in acidic sulfur-rich environments, can strongly sorb both As(V) and Sb(V). However, little is known regarding the mechanisms that control simultaneous co-sorption of As(V) and Sb(V) to jarosite. We investigated the mechanisms controlling As(V) and Sb(V) sorption to jarosite at pH 3 (in dual and single metalloid …

Like arsenic, antimony is widely distributed on earth, usually at low concentrations, e.g., 4.3 to 7.9 ppm in soils . In addition to terrestrial sources, this element can be detected in oceans and freshwater environments in the parts per billion range. The metalloid and its inorganic compounds find a variety of industrial uses; the element is a ...

Here, we review the recent advances in understanding of arsenic and antimony transport pathways in eukaryotes, including a dual role of aquaglyceroporins …

Arsenic and antimony are toxic metalloids, naturally present in the environment and all organisms have developed pathways for their detoxification. The most effective metalloid tolerance systems in eukaryotes include downregulation of metalloid uptake, efflux out of the cell, and complexation with phytochelatin or glutathione followed by sequestration …

A chemico-toxicological similarity between arsenic and antimony exists and their toxicology is often seen. Indeed, both elements possess several common properties, e.g. they are clastogenic but not mutagenic in the trivalent state and they have a carcinogenic potential: trivalent arsenicals are known to be human carcinogens and …

In December 2014, the lead content in the bottom sediment in Sławków was nearly 6000 mg/kg. In the river water, only the inorganic arsenic speciation forms were found. Sb(V), As(V) and Cr(III) were dominant. Studies have shown that arsenic, antimony and chromium were mainly bound to oxides, organic matter and sulphides in the bottom …

The toxicity of antimony is regarded to be on par with, or even higher than, that of arsenic, and the inorganic form of antimony, Sb(III), is far more toxic, than the …
