Toxicological Profile for Antimony and Compounds. Agency for Toxic Substances and Disease Registry (ATSDR) Toxicological Profiles. PMID: 37184169. Bookshelf ID: …
Antimony trioxide (Sb2O3) is a synergist in flame retardants, a catalyst in polyethylene terephthalate (PET) production, and a material used in various industrial process and consumer goods. Antimony trioxide is a potential public health concern because of occupational exposure and a suggested association with cancer based on animal …
antimony (Sb), a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table ). Antimony exists in many allotropic forms (physically distinct conditions that result from different arrangements of the same atoms in molecules or crystals ). Antimony is a lustrous silvery bluish white solid that is very brittle and has a ...
Antimony trioxide is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals and supporting evidence from mechanistic studies. The data available from studies in humans are inadequate to evaluate the relationship between human cancer and exposure …
Trivalent antimony compounds are used in the production of flame retardants, plastics, lead–acid batteries, lead alloys, glass, pigments, and paints. Occupational exposure can occur through mining, copper smelting, production of antimony compounds, manufacture and recycling of batteries and electronic waste, and among firefighters.
GLOSSARY. The process by which a substance crosses biological membranes and enters systemic circulation. Absorption can also refer to the taking up of liquids by solids, or of gases by solids or liquids. Exposure to a chemical for a duration of ≤14 days, as specified in the Toxicological Profiles.

Exposure to antimony compounds would be expected from brake dust in high-traffic areas, smelting plants, bottled water, and dust from aerosolized soil. Like TDI, antimony inhibited ceramide-family lipid production in Roseomonas mucosa and activated TRPA1 in human neurons. While further epidemiologic research will be needed to directly evaluate ...

In the United States, antimony(III) trioxide (Sb2O3) is the most commercially significant form of processed antimony. In nature, Sb2O3 exists in minerals such as valentinite and senarmontite (ATSDR 2017; Roper et al. 2012). Antimony is found in nature in these and other mineral species, often in association with arsenic compounds due to their similar …
Workers can be exposed during smelting, manufacture of antimony compounds, glass, textiles, and batteries, and electrical-waste processing. Non-occupational exposures occur via water, air, soil, consumer products, and tobacco. Weapons-grade tungsten (with nickel and cobalt) alloy is used in armour-penetrating munitions.

These studies have investigated the toxicity of several trivalent antimony compounds (antimony trichloride, antimony potassium tartrate, and antimony trioxide) and metallic antimony and found differences in effect levels that may be related to solubility and absorption efficiency. The most sensitive effects were decreases in blood glucose ...
This chapter provides an overview of U.S. exposures, a summary of health effects based on evaluations of existing toxicologic, epidemiologic, and toxicokinetic information, and an overview of the minimal risk levels. This is designed to present interpretive, weight-of-evidence discussions for human health endpoints by addressing the following questions: …
THIS chapter reviews the physical and chemical properties, toxicokinetics, toxicological, epidemiological, and exposure data on pentavalent antimony (antimony pentoxide and sodium antimonate). The subcommittee …
INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure …

Antimony or antimony compounds have been identified in at least 563 of the 1,854 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (ATSDR 2017). However, the number of sites in which antimony has been evaluated is not known. The number of sites in each state is shown in Figure 5-1. Of …
Purities of commercially available trivalent and pentavalent antimony compounds have been noted to vary from 99% to 99.999% for antimony(III) oxide (ChemicalBook, 2021a; Sigma-Aldrich, 2022a), 98% …
Antimony and Antimony Compounds - Grund - - Major Reference … Antimony is a component of many lead and tin alloys, which are important materials for making bearings and solders. Preparation, properties, and usage of the antimony halides, oxides, sulfides, and other compounds, as well as organometallic compounds are described.
Antimony metal is stable under ordinary conditions. Antimony is a poor conductor of heat and electricity . Antimony forms complex ions with organic and inorganic acids. Stable complexes, such as Sb 2 S 4 2−, may form when antimony is in the presence of sulfur (Bodek et al. 1988). Stibine (SbH 3) is a gaseous antimony compound in which ...

This monograph focuses on alloys containing tungsten, nickel, and cobalt that are used in the production of military weapons. Such alloys typically contain approximately 91–93% tungsten, 3–5% nickel, and 2–4% cobalt (Andrew et al., 1991, as cited in Miller et al., 2004), and are sometimes referred to as "tungsten heavy alloys" or "weapons-grade tungsten …
Economic Aspects 16. Toxicology The article describes the properties, production, and usage of the element antimony and its primary compounds. Stibnite, which is referred to as crude antimony when its Sb2S3 content is above 90 %, has a low melting point and it can be extracted by melting (liquidation).
The results of several synthetic strategies suggest that these methylantimony(V) compounds are either environmentally inaccessible or polymeric in nature. Pure …
