What to avoid if you are allergic to cobalt?

What causes cobalt allergy?

• Jewellery [see Jewellery allergy]
• Metal household items (eg, cutlery, zippers, coins, keys,)
• Cosmetics – especially eye shadow, blushers, and compact powders [see Contact reactions to cosmetics]
• Leather.
• Clothing and shoes [see Textile contact dermatitis, Shoe contact dermatitis]

How do you get cobalt out of your body?

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.

What diseases can cobalt cause?

* Cobalt may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. * Cobalt may affect the heart, thyroid, liver and kidneys. * Repeated exposure to Cobalt dust can cause scarring of the lungs (fibrosis) even if no symptoms are noticed.

How do I know if I have a metal allergy?

Overview of a Metal Allergy
Long-term exposure to metal that you are allergic to can cause your skin to become dark and leathery. Symptoms include: rashes, redness, swelling and pain. The most common reaction comes from when people wear nickel, such as jewelry.

Does all B12 have cobalt?

Answer: Cobalt is one of the components of vitamin B12, also known as cobalamin.

How do you test for cobalt toxicity?

The diagnosis of cobalt toxicity is based on the combination of clinical history and laboratory confirmation. The preferred method of testing is inductively coupled mass spectrometry for metal ion value determination, and the typical patient specimens tested include serum, whole blood, or urine.

How much cobalt is toxic to humans?

The LD ₅₀ value for soluble cobalt salts has been estimated to be between 150 and 500 mg/kg. Thus, for a 100 kg person the LD₅₀ would be about 20 grams. Soluble cobalt(II) salts are “possibly carcinogenic to humans” (IARC Group 2B Agents).

Is cobalt absorbed through the skin?

Cobalt is mainly absorbed from the pulmonary and the gastrointestinal tracts. Absorption through the skin can occur but is low. Concomitant exposure to tungsten carbide increases the pulmonary absorption rate of cobalt metal.

What fruits are high in cobalt?

There is no recommended dietary intake of cobalt, however, for proper assimilation of vitamin B12, cobalt is essential. Some of the dietary sources that are abundant in cobalt include red meat, milk, fish, cabbage, figs and turnips.

Does cobalt accumulate in the body?

Cobalt does not accumulate in the organism and is rapidly excreted in urine. The concentration of cobalt in urine or in blood is proposed as a biomarker of recent exposure to soluble cobalt species.
