Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt is an essential element for health in animals in minute amounts as a component of Vitamin B12. A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia.
How cobalt enters the body
Exposure to cobalt metal dust is most common in the fabrication of tungsten carbide. Another potential source is wear and tear of metal-on-metal hip prostheses; however, this is a relatively uncommon phenomenon with 18 reported cases being documented in the medical literature.
