Cobalt Poisoning

Cobalt poisoning can occur when you are exposed to large amounts of cobalt. There are three basic ways that cobalt can cause poisoning. You can swallow too much of it, breathe too much into your lungs, or have it come in constant contact with your skin.

Usually you have to be exposed to high levels of cobalt for weeks to months to have symptoms. However, it is possible to have some symptoms if you swallow a large amount of cobalt at once.

The most worrisome form of cobalt poisoning occurs when you breathe too much into your lungs. This usually will only happen in industrial settings where large amounts of drilling, polishing, or other processes release fine particles containing cobalt into the air. Breathing in this cobalt dust can cause a lot of chronic lung problems. If you breathe in this substance for long periods, you will likely develop problems breathing similar to asthma or more permanent problems, such as pulmonary fibrosis.

Cobalt poisoning that occurs from constant contact with your skin will likely cause irritation and rashes that will go away slowly.

Swallowing a large amount of absorbable cobalt at one time is very rare and likely not too dangerous. This may cause nausea and vomiting. However, if you swallow a large amount of cobalt over longer periods of time, serious health problems can occur, including:

  • Cardiomyopathy (a problem where your heart becomes big and floppy and has problems pumping blood)
  • Possible nerve problems
  • Thickening of your blood
  • Thyroid problems
