The concentration of antimony in ambient air ranges from less than 1 nanogram per cubic meter (ng/m 3) (0.000001 milligram per cubic meter mg/m 3) to about 170 ng/m 3 (0.000170 mg/m 3). However, near factories that convert antimony ores into metal, or make antimony oxide, concentrations may be greater than 1,000 ng/m 3 (0.01 mg/m 3). (1)
Antimony is a silvery-white metal that is found in the earths crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing.
Antimony oxides (primarily antimony trioxide) are used as fire retardants for plastics, textiles, rubber, adhesives, pigments, and paper.

The chemical behaviour of antimony is as complex as that of arsenic, its neighbour in the periodic table (Wiberg, 1985). It is speculated that antimony could be a natural co-contaminant with arsenic in some drinking-waters (Gebel, 1999b). Soluble forms of antimony (and arsenic)

Antimony is a regulated contaminant that poses both acute and chronic health effects in drinking water. Previous reports suggest that polyethylene terephthalate (PET) plastics used for water bottles in Europe and Canada leach antimony, but no studies on bottled water in the United States have previously been conducted.
Antimony trichloride is an inorganic chloride salt with formula SbCl3. It is used as a reagent for detecting vitamin A and related carotenoids, reacting with the carotenoid to form a blue complex that can be measured by colorimetry (the Carr-Price test). Solutions of antimony trichloride were formerly used for dissolving and removing horn stubs ...

Mar 12, 2016 arsenic, antimony, tin Arsenic when present in the blast furnace charge is largely volatilized and when condensed, contaminates the dust chamber by-products. Retreatment of the flue dust and fume is expensive, but is a source of salable arsenic in most cases and this tends to offset the added cost of recovering the other values in the dust.
May 19, 2019 Estimates of the abundance of antimony in the Earths crust range from 0.2 to 0.5 parts per million. Unlike typical metals, antimony is not malleable, but hard and brittle and can be crushed to a powder. Compared with metals, antimony is a poor conductor of electricity and heat.
Antimony trichloride is an inorganic chloride salt with formula SbCl3. It is used as a reagent for detecting vitamin A and related carotenoids, reacting with the carotenoid to form a blue complex that can be measured by colorimetry (the Carr-Price test).
Production of antimony concentrate is reflected in the following figures, which represent thousands of tons of Sb 1418 in South Africa, 1114 in Bolivia, 35 in Mexico, 23 in Turkey, and 12 in Morocco. The annual production of antimony in capitalist and developing countries
The concentration of antimony in air ranges from a very small part of a nanogram (1 nanogram equals a billionth of a gram) in a cubic meter (m) of air (ng/m) to about 170 ng/m.
