Nickel (Ni) is a naturally occurring metal and widely used industrial element. In trace amounts, it is generally harmless, but excessive exposure can cause health issues such as skin irritation, allergic dermatitis, and respiratory problems. Nickel is also classified as a potential carcinogen, with higher risks observed in occupational environments where exposure levels are elevated.
Testing for nickel levels is advised for individuals with occupational exposure, such as those working in metallurgy, mining, and electroplating. People with chronic dermatitis or allergic reactions without a clear cause might also benefit, as nickel is a common allergen. Residents in areas with high environmental nickel pollution or near industrial sites should consider testing too.
Occupational exposure in nickel refining, metal processing, and electroplating industries is common. Environmental sources include nickel-contaminated soil and water, particularly near industrial areas. Nickel is also present in many everyday items like jewelry, coins, and stainless steel cookware, leading to dermal exposure.
To detox from nickel, the first step is reducing exposure, especially in occupational settings with appropriate safety measures. For those with nickel allergy, avoiding nickel-containing objects and choosing nickel-free products is crucial. The body naturally eliminates small amounts of nickel, but in cases of high exposure, intervention such as chelation therapy may be necessary, under guidance. A diet low in nickel-containing foods can also help reduce overall exposure.
