“…The results are in accordance with XPS surface analysis of euro coins taken from general circulation, 9 where the presence of Cl, C and OH was indicated. However, that study also showed Ni enrichment compared with the bulk composition.…”

“…Similar results were obtained for the euro coins' investigations of Fournier and Govers 10, 11 and Nestle et al 12. Gou et al 13 reported nickel enrichment on both segments of the 1‐euro coins. Nickel is considered to be the most important allergen today 14.…”

Corrosion processes of strings on musical instruments occur frequently. Such processes significantly influence sound quality, but also human health because metals may provoke skin allergy. Therefore, in this study the corrosion process of six guitar strings and metal ions release associated with nickel allergy was monitored after immersion in sweat solution for 28 days. Dissolution of metal ions was measured as a function of time, and the changes of the samples after 28 days were studied by SEM/EDS. The results have shown that the amounts of dissolved metal ions in corrosive solution are decreasing in the following order: Fe 3þ < Sn 2þ < Mn 2þ < Si 4þ < Ni 2þ . The corrosion of electric guitar strings in artificial sweat solution was determined by the solubility of samples. The electric guitar strings E6, A5 and D4 corrosion kinetic in artificial sweat followed parabolic rate relation, while g3, h2 and e1 strings followed linear rate relation. After the 4 weeks of monitoring, the quantities of the nickel eluted ions did not exceed the limits prescribed by standard regulations. Therefore, such items do not present a threat to human health.

“…Un moyen d'analyser le matériau plus près de la surface est la méthode XPS, qui sonde une couche de quelques nanomètres. Une telle analyse a été effectuée par Glou et al [14] pour le coeur en cupronickel des pièces d'un euro, avec pour résultat un rapport Cu/Ni proche de 1. La variation de composition est ici considérable.…”
