Cobalt | NIOSH | CDC
Cobalt (Co) is a hard, gray metal that occurs naturally. It is found in rocks, soil, water, plants, and animals, including people. It can harm the eyes, skin, heart, and lungs. Exposure to cobalt may cause cancer. Workers may be harmed from exposure to cobalt and cobalt-containing products. The level of harm depends upon the dose, duration, and work being done.
