Abstract:

Background. The groundwater of Argentina's Chaco plain presents arsenic levels above those suitable for human consumption. Studies suggest skin disorders among local populations caused by arsenic intake. The relationship between urinary arsenic and arsenic in drinking water is well known, but urinary arsenic alone is not enough for risk assessment due to modulating factors such as the intake of selenium and antimony. Objectives. Determining the relationship between urinary arsenic, selenium and antimony could contribute to the study of arsenic metabolization in humans. Methods. Arsenic, seleni

Abstract:

Arsenic and antimony occur in drinking water due to natural weathering or anthropogenic activities. There has been growing concern about their impact on health. The aim of this study was to assess the efficiency of a granular ferric oxide adsorbent medium to remove arsenic and antimony from drinking water via rapid small-scale column tests (RSSCTs). Three different water matrices – deionized, raw water treated with a reverse osmosis domestic device and raw water – were spiked with arsenic and/or antimony to a concentration of 100 μg L−1. Both elements were successfully adsorbed onto the medium

Abstract Arsenic and antimony compounds are used to treat endemic diseases, such as cancer, leishmaniasis, and schistosomiasis, in spite of their toxicity. Several studies seeking the development and characterization of nanocarrier systems such as liposomes are being carried out with the aim of developing new drug delivery systems and minimizing the toxicity of these drugs. However, the lack of reference methods to quantify these semimetals within a liposomal matrix hinders the QC of these formulations.

The accumulation of arsenic and antimony compounds in environmental objects as a result of the development of mineral deposits is a source of public health risk.

This study examined how pH hydrolysis affects the recovery process for antimony extracted from spent electrolytes. Various OH− reagents were used to adjust the pH levels. The findings reveal that pH plays a crucial role in determining the optimal conditions for extracting antimony. The results show that NH4OH and NaOH are more effective compared to water, with optimal conditions at pH 0.5 for water and pH 1 for NH4OH and NaOH, resulting in average antimony extraction yields of 90.4%, 96.1%, and 96.7%, respectively.

High antimony composition is achieved by pulsing the arsenic flow to reduce the effective arsenic partial pressure while keeping the antimony partial pressure fixed. This increases the antimony vapor phase composition while allowing the antimony partial pressure to be kept low enough to avoid antimony condensation on the growth mask.

SUMMARY A significant 19th century public health problem was that the inhabitants of many houses containing wallpaper decorated with green arsenical pigments experienced illness and death. The problem was caused by certain fungi that grew in the presence of inorganic arsenic to form a toxic, garlic-odored gas. The garlic odor was actually put to use in a very delicate microbiological test for arsenic. In 1933, the gas was shown to be trimethylarsine. It was not until 1971 that arsenic methylation by bacteria was demonstrated. Further research in biomethylation has been facilitated by the devel

Abstract:

This paper aims to discover the mechanism of removal of arsenic and bismuth from copper electrolyte under the function of antimony. The precipitate was obtained from a synthetic copper electrolyte containing 185g/L sulfuric acid, 45g/LCu2+, 10g/LAs, 0.5g/LBi and 1.2g/LSb. The structure, morphology and component of the precipitate are clarified by methods of chemical analysis, SEM, XRD, TEM and IR spectroscopy. The precipitate consists of 27.08% arsenic, 15.12% antimony, 12.08% bismuth. There are many irregular blocks, and dendritic particles on the surface.The characteristic bands in the IR sp

Abstract:

The results of studies on the distribution of rare elements among the products of distillation processing of polymetallic mattes are present in this article. Schemes of the developed technological equipment for the implementation of the extraction processes of rare elements via the vacuum distillation of mattes are presented. Technological tests were performed with a matte of lead, copper, and antimony plants at 1100–1250 °C and a pressure of up to 700 Pa. It was established that As, Cd, Bi, In, and Ge, by more than 90% in total, are extracted into condensate and dust in the distillation proce

Abstract:

ABSTRACT Arsenic is one of the most important global environmental pollutants. Here we show that the cyanobacterium Synechocystis sp. strain PCC 6803 contains an arsenic and antimony resistance operon consisting of three genes: arsB, encoding a putative arsenite and antimonite carrier, arsH, encoding a protein of unknown function, and arsC, encoding a putative arsenate reductase. While arsB mutant strains were sensitive to arsenite, arsenate, and antimonite, arsC mutants were sensitive only to arsenate. The arsH mutant strain showed no obvious phenotype under the conditions tested. In vivo the

Abstract:

ABSTRACTAntimony (Sb) is a toxic metalloid that occurs widely at trace concentrations in soil, aquatic systems, and the atmosphere. Nowadays, with the development of its new industrial applications and the corresponding expansion of antimony mining activities, the phenomenon of antimony pollution has become an increasingly serious concern. In recent years, research interest in Sb has been growing and reflects a fundamental scientific concern regarding Sb in the environment. In this review, we summarize the recent research on bacterial antimony transformations, especially those regarding antimo

Abstract:

For the purpose of establishing an effective exploration model of antimony deposit as a final goal. minor elements in stibnite ( Sb 2 S 3) were analyzed by micro-PIXE. Samples were taken from the largest antimony mine in the world. Xikuangshan. Hunan. China. Measurements were carried out using 1 MeV proton to avoid the problem where low energy tail of K X-ray peaks of antimony could mask small peaks of interest. As a result. arsenic at a concentration of around 0.2 wt % was successfully detected for the stibnite crystals that contact calcite but not those that contact quartz.

Abstract:

Environmental contextToxicity and mobility of antimony and arsenic in aqueous systems are largely determined by their speciation and redox chemistry. In a highly contaminated freshwater system, one antimony species (dissolved SbV) dominated, while dissolved arsenic was more responsive to environmental conditions. Arsenic (as AsV) increased significantly during a drought period; this increase in As mobility presents a threat for first flush events and water contamination in a changing climate.AbstractAqueous and solid-state antimony (Sb) and arsenic (As) speciation is assessed in an Australian
