The migration of nickel was studied for a set of twelve new units of piercing jewellery and eleven ones used for longer than one year. First, the surface of the samples was analysed using ED XRF and then samples were submerged into the artificial sweat solution for 168 hours at 30C. The resulting solutions were then analysed using ICP OES. A significant migration of nickel was found for four samples used, whereas only one of them was considered to exceed the migration limit given by ČSN EN 1811 +A1. Regrettably, no connection between elemental composition of particular jewellery sample measured by ED XRF and corresponding Ni release to the artificial sweat was observed.
