Source: Found naturally, most common source for contamination is as discharge from industrial processes such as the petroleum refinery.

Summary: Antimony is element 51 on the periodic table and is found naturally in rocks. Ores may be mined so that stronger alloys with oxygen are formed. These alloys are used to produce sheet and pipe metal, castings, lead acid storage batteries, bullets, and has applications in ceramics, fireworks, textiles, and plastics. Antimony is insoluble in water. If exposed to a flame antimony may decompose to antimony oxide which is toxic if inhaled. Antimony oxide is used as a flame retardant. Pure antimony is used in the production of semiconductors. Antimony may contaminate water sources as discharge from oil refineries.
