Young children who mouth or swallow jewelry containing cadmium may be exposed to as much as 100 times the recommended maximum exposure limit for the toxic metal, according to research published online March 4 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP).
The study, conducted by Dr. Jeffrey Weidenhamer, professor of chemistry at Ashland University in Ashland, Ohio, measured bioavailability, or how much cadmium leached out of the jewelry. The research also found that damaged pieces of jewelry in some cases leached up to 30 times more cadmium than undamaged pieces.
