Metal release from gold‐containing jewellery materials: no gold release detected

Metal release from 13 different gold-containing jewelry alloys stored for 1 and 3 weeks in artificial sweat was analysed. For chemical analysis, inductively-coupled plasma detection (ICP) and atomic absorption spectrophotometry (AA), with flame and with furnace, were used. No release of gold was detected. It is unlikely that skin contact with gold-containing metallic items such as jewelry is responsible for inducing contact allergy to gold or allergic contact dermatitis due to the gold. The patch-test reactivity to gold sodium thiosulfate needs to be explained by some other mechanism(s).
