摘要

研究了一套12个新穿孔首饰和11个使用时间超过一年的首饰的镍迁移情况。首先，用ED XRF对样品表面进行分析，然后将样品浸入人工汗液中，在30°C下浸泡168小时。然后使用ICP OES分析得到的解决方案。在所使用的四个样品中发现了镍的明显迁移，而其中只有一个被认为超过了CSN EN 1811给出的迁移限制

Nickel Release from Piercing Jewellery

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 30∘C. 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 CSN EN 1811
