Survey and health assessment of chemical substances in jewelleries
Appendix L: Correlation between migration and content of metal
The tables below shows the correlation between migration and content of metal.
Table: Correlation between content (according to the XRF-screening) and migration of metal. A line indicates that the XRF-screening did not show a content of metal. However, this does not guarantee with 100% certainty that the metal does not exist in a small amount in the jewellery. The reason for this being that the uncertainty associated with the XRF-screening is relatively large when it is attempted to locate small amounts.
