Abstract

Neutron activation analysis has been applied to analyse ear piercing studs manufactured with three different types of metallic materials and also in the analyses of cell culture media in which these studs were immersed. Results obtained in these analyses indicated the release of metal from the studs to the culture media. Zn and Fe were found, respectively, in the extracts of gold coated copper-zinc alloy and stainless steel. These findings were correlated with the results already obtained for studs surface analysis by scanning electron microscopy and for the cytotoxicity tests of culture extracts.
