    Many metals, particularly heavy metals are toxic, but some are essential, and some, such as bismuth, have a low toxicity. Metals in an oxidation state abnormal to the body may also become toxic: chromium(III) is an essential trace element, but chromium(VI) is a carcinogen. Only soluble metal-containing compounds are toxic.

    Niobium is a metal resembling titanium, but it is softer and heavier. When using niobium in a piercing jewelry it has to be as pure as possible, the threshold value being 99.9% niobium. This is sometimes called "999 Niobium". Impurities in low quality material can lead to allergies. Pure niobium does not react to body fluids, oxygen or
