Longterm inhalation of antimony trioxide dust or antimony ore dust (46 % antimony, mainly as antimony trisulfide) caused lung tumours in rats. There is evidence of an increase in lung cancer mortality in humans. Investigations in humans and animals indie a clastogenic potential of antimony and its inorganic compounds.
Antimony, tin, arsenic, and calcium are the most common alloying elements. Antimony generally is used to give greater hardness and strength, as in storage battery grids, sheet, pipe, and castings. Antimony contents of leadantimony alloys can range from to 25%, but they are usually 2 to 5%.
Antimony is increasingly being used in microelectronics. A compound of antimony, antimony (III) sulfide, was known to man as far back as 3000 BC. It is not known who discovered it, however. Pieces of a vase dating to this time period were found on the territory of what is Iraq today. A copper object plated with this element was found in Egypt ...
Apr 02, 2013 · In a new peerreviewed scientific study published on March 26, 2013 in the journal Food Chemistry, Spanish researchers report migration of antimony from polyethylene terephthalate (PET) plastic (SánchezMartínez et al. 2013).Using migration testing rules for plastics established in the EU's Plastics Regulation (), the scientist found levels of elemental antimony (Sb) in food simulants well ...
Antimony (Latin: stibium) is a chemical element with symbol Sb and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were used for cosmetics; metallic antimony was also known, but it was erroneously identified as lead.
· Domestic market: the market price of antimony ingot is low this week, the market trading is limited, and the transaction is low. By the end of the year, most enterprises have completed the settlement, some manufacturers have suspended the shipment, the downstream purchase intention is low, and the overall market is mainly waiting.
Excretion Antimony compounds are eliminated mainly in the urine, with small amounts appearing in faeces via bile after conjugation with glutathione. A significant amount of antimony excreted in bile undergoes enterohepatic circulation (Bailly et al, 1991). ... Radiological evidence of pneumonitis was found in six workers exposed to antimony ...
Sep 29, 2015 · The environmental behaviour of antimony (Sb) is gathering attention due to its increasingly extensive use in various products, particularly in plastics. Because of this it may be expected that plastic waste is an emission source for Sb in the environment. This study presents a comprehensive field investigati Waste and Recycling: Sources and Resources
Sep 23, 2020 · Antimony (Sb) is a toxic element widely distributed in the lithosphere that mainly associates with arsenic (As) as a sulfide or oxide. Sb and As are nitrogengroup elements with similar valence electron configurations and chemical speciation.
Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were used for cosmetics; metallic antimony was also known, but it was erroneously identified as lead upon its discovery.
Elevated levels of arsenic (As) and antimony (Sb) in water and sediments are legacy residues found downstream from goldmining activities at the Giant Mine in Yellowknife, Northwest Territories (NWT), Canada. To track the transport and fate of As and Sb, samples of minewaste from the mill, and surface water, sediment, porewater, and vegetation downstream of the mine were collected.
Aug 02, 2012 · Antimony definition is stibnite. 2: a trivalent and pentavalent metalloid element with atomic number 51 that commonly occurs in a brittle, metallic, silvery white crystalline form and that is used especially in alloys, semiconductors, and flameretardant substances — .
Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
