Antimony in the environment: a review focused on natural ...

01/11/2002· This hypothesis is supported by the existence of antimony oxidising bacteria (Stibiobacter) capable of oxidising Sb 2 S 3 to Sb(V) minerals in the oxidising zone overlying antimony ore deposits (Lyalikova, 1978). Cutter (1992) estimated the Sb(III) oxidation rate by using the depth profiles for antimony species in the upper 100 m of the Black Sea.

The name antimony was derived from the Greek words, “anti,” meaning not, and “monos,” meaning alone, because antimony is normally found in complex ore bodies. In ancient times, powdered stibnite was, along with lead sulfide, a principal ingredient of kohl, the thick black paste used by the Egyptians and others as a cosmetic for coloring eyebrows and lining the eyes.

Antimony and arsenic compounds are known to have a genotoxic potential. Soil contamination with these elements can be due to the presence of natural ore sources of fahlore (gray copper). As a result, human and animal populations may be highly exposed. The sister chromatid exchange (SCE) test is an adequate tool for the sensitive detection of antimony and arsenic genotoxicity. We used this ...

Antimony and health | The BMJ

13/05/1995· Antimony is a metal in group Vb of the periodic system, just below arsenic, with which it shares several chemical and toxicological properties. Considered to be a non-essential trace element, it occurs naturally in the trivalent and pentavalent states with sulphur, mainly as stibnite ore (Sb2S3).1 Antimony's main applications are industrial—it is used in alloys for hardening lead (for ...

Antimony - Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) 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 powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was erroneously identified as lead upon its discovery. The earliest known description of the metal in the West was written in 1540 by
