Cobalt is required in the diet in minute amounts and a deficiency in humans is rare. However, cobalt toxicity is more common. Cobalt and cobalt compounds are widely distributed in nature and excessive exposure can cause deleterious immune-mediated health effects.
The full entry for cobalt is undergoing validation and will be added to OpeN-Global soon.
