Why is cobalt so toxic?

Sometimes, metal particles (cobalt) are released as the metal ball grinds against the metal cup when you walk. These metal particles (ions) can get released into the hip socket and sometimes the bloodstream, causing cobalt toxicity

cobalt toxicity

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.
