Antimony oxide production has been determined by ACGIH to be a carcinogenic risk. Antimony trioxide has been identified by the EPA as a suspected lung carcinogen. Historical studies have concluded that exposure to elevated levels of antimony oxide may cause lung carcinoma.
antimony trioxide. Antimony trioxide is produced by oxidizing antimony sulfide ore or antimony metal in air at 600–800°C (Avento and Touval 1980). In 1987 and 1988, 18,758, and 18,226 metric tons of the oxide were produced, respectively (U.S. Bureau of Mines 1989). Consumption trends have generally paralleled those of production.

Antimony trioxide is used as a flame retardant in textiles, as a catalyst, and as an opacifier in glass, enamels and ceramics. Antimony tetroxide is used as an oxidation catalyst. Antimony trisulphide is used in fireworks, matches, as a pigment, and in the manufacture of ruby glass.
Antimony(III) oxide has suspected carcinogenic potential for humans. Its TLV is 0.5 mg/m 3, as for most antimony compounds. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.

THIS chapter reviews the physical and chemical properties, toxicokinetics, toxicological, epidemiological, and exposure data on antimony trioxide. The subcommittee used that information to characterize the health risk from exposure to antimony trioxide. The subcommittee also identified data gaps and recommended research relevant for determining the health risk from exposure to antimony trioxide.
Arsenic trioxide is an inorganic compound with the formula As 2 O 3.This commercially important oxide of arsenic is the main precursor to other arsenic compounds, including organoarsenic compounds.Approximately 50,000 tonnes are produced annually. Many applications are controversial given the high toxicity of arsenic compounds.
Trivalent antimony readily enters red blood cells, has an extended half-life on the order of weeks to months, and is eliminated predominantly through the bile. Pentavalent antimony resides in the plasma, has a relatively short half-life on the order of hours to days, and is …

The homogeneity of antimony trioxide in the diet was determined by analysis of samples from the low and high dose levels. Samples were taken from three separate levels in the mixer. Variation between samples was 5%. The chemical stability of antimony trioxide in the diet has been determined at these dose levels for a period of up to 98 days.
Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.

Antimony is found in ores or other minerals, often combined with oxygen to form antimony trioxide or with sulfur to form stibnite. Antimony can exist in one of four valences in its various chemical and physical forms: -3, 0, +3, and +5. It is used in metal alloys, storage batteries, solder, sheet ...

Pseudo-Outbreak of Antimony Toxicity in Firefighters --- Florida, 2009. Antimony oxides, in combination with halogens, have been used as flame retardants in textiles since the 1960s. Uniforms made from fabric containing antimony are common among the estimated 1.1 million firefighters in the United States.

Antimony (Sb) is used in metallurgical processes, paints and enamels, various textiles, rubber, and fire retardation (antimony trioxide). Antimony is a common urban air pollutant, occurring at an average concentration of 0.001 µg/m 3 (Beliles, 1979). Exposure to antimony may occur via inhalation and by ingestion of contaminated food.
Aluminium oxide is on the EPA's Toxics Release Inventory list if it is a fibrous form. Amphoteric nature. Aluminium oxide is an amphoteric substance, meaning it can react with both acids and bases, such as hydrofluoric acid and sodium hydroxide, acting as an acid with a base and a base with an acid, neutralising the other and producing a salt.
