Do jewellery and piercing posts release nickel, lead, or cadmium?

The draft corpus names Murphy and colleagues 2016 (doi:10.5696/2156-9614-6-11.47) among piercing-post papers. That paper is not in the saved sources, so its values are not repeated. No jewellery item is ranked. Nickel allergy and the EFSA intake value are on the nickel page.

What is not available

No release rate was verified from a saved paper.

What's safe to buy

The Heavy Metal Tested and Certified public register listed no licensees on 15 October 2026. That page reported 0 certified brands and 0 certified products, and it stated that no brand has completed the three-lot baseline. A specimen layout on the register is an illustration, not a licensee. This page does not name or rank any brand.

The program states that certification is a measurement of a product against a published limit, not a statement that the product is safe. If a licensee is later listed for this category, it will be on the register.
