What disease is caused by nickel?

Nickel is one of the most common causes of allergic contact dermatitis: a skin rash or irritation caused by touching an allergen.

Can nickel be absorbed through the skin?

Coins, plumbing fixtures, certain shampoos and detergents, pigments and jewelry can contain small amounts of nickel that can be absorbed through the skin. Over time, direct skin contact with these objects may cause a person to become sensitized to the metal and to experience an allergic reaction to nickel.

What is the role of nickel in human body?

Does nickel leave the body?

Some nickel particles may leave your body with mucus that you spit out or swallow. Nickel that comes into contact with your skin can also enter the bloodstream, where it travels mainly to the kidneys. Nickel from the bloodstream can leave the body through urine.

Is nickel in stainless steel toxic?

Toxicological studies show that oral doses of nickel and chromium can cause cutaneous adverse reactions such as dermatitis. Additional dietary sources, such as leaching from stainless steel cookware during food preparation, are not well characterized.

What does nickel do to your lungs?

If the particles do not dissolve easily in water, the nickel may stay in your lungs for a long time. Some of these nickel particles can leave the lungs with mucus that you spit out or swallow. The most common harmful health effect is an allergic reaction. About 10%-20% of people are sensitive to nickel.
