Risks of nickel exposure: Fact Sheet VI
Nickel (Ni) is a natural element of the earth's crust and, therefore, small amounts of it are found in food, water, soil, and air. Individuals also may be exposed to nickel in occupations involved in its production, processing, and use, or through contact with everyday items such as nickel-containing jewellery and stainless steel cooking and eating utensils, and by smoking tobacco.
