Heavy metal.Encyclopedia Entry for Cobalt :Cobalt poisoning. Cobalt.Cobalt is a component of vitamin B12, an essential vitamin. Cobalt may also be found in: Alloys Batteries Chemistry/crystal sets Drill bits, saw blades, and other machine tools Dyes and pigments (cobalt blue) Magnets Some metal-on-metal hip implants Tires Cobalt was once used as a stabilizer in beer foam. It caused a condition called 'beer-drinker's heart,' which resulted in heart muscle weakness. This list may not be all-inclusive.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 lead to chronic lung problems. If you breathe in this substance for long periods, you will likely develop breathing problems that are similar to asthma or pulmonary fibrosis, such as shortness of breath and decreased exercise tolerance. Cobalt poisoning that occurs from constant contact with your skin will likely cause irritation and rashes that go away slowly. Swallowing a large amount of absorbable cobalt at one time is very rare and is likely not very dangerous. It may cause nausea and vomiting. However, absorbing a large amount of cobalt over longer periods of time can lead to serious health problems, such as: Cardiomyopathy (a problem where your heart becomes big and floppy and has problems pumping blood) Deafness Nerve problems Ringing in the ears (tinnitus) Thickening of the blood Thyroid problems.If you or someone you know has been exposed to cobalt, the first step is to leave the area and get fresh air. If cobalt came in contact with the skin, wash the area thoroughly.If possible, determine the following information: Person's age, weight, and condition (for example, is the person awake or alert?) Name of the product (ingredients and strengths, if known) Time it was swallowed Amount swallowed However, DO NOT delay calling for help if this information is not immediately available.Your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This hotline number will let you talk to experts in poisoning. They will give you further instructions. This is a free and confidential service. You should call if you have any questions about poisoning or poison prevention. You can call 24 hours a day, 7 days a week.If you swallowed a large amount of cobalt, or you are starting to feel sick from long-term exposure, you should go to an emergency room. Treatment for skin contact : Since these rashes are rarely serious, very little will be done. The area may be washed and a skin cream may be prescribed. Treatment for lung involvement : Breathing problems will be treated based on your symptoms. Breathing treatments and medications to treat swelling and inflammation in your lungs may be prescribed. X-rays and EKG (electrocardiogram, or heart tracing) may be done. Treatment for swallowed cobalt : The health care team will treat your symptoms and order some blood tests. X-rays and EKG (electrocardiogram, or heart tracing) may be performed. In the rare case that you have large levels of cobalt in your blood, you may need hemodialysis (kidney machine) and get medicines (antidotes) to reverse the effects of the poison. Treatment for signs of cobalt toxicity from a metal-on-metal hip implant may include removing the implant and replacing it with a traditional hip implant.People who get sick from being exposed to large amounts of cobalt on one single occasion usually recover and have no long-term complications. The symptoms and problems associated with long-term cobalt poisoning are rarely reversible. People who have such poisoning will likely have to take medicine for the rest of their life to control the symptoms.Cobalt chloride; Cobalt oxide; Cobalt sulfate.Aronson JK. Cobalt.
