May has not been a good month for Cadmium.

On May 10, the U.S. Consumer Product Safety Commission announced a voluntary recall of metal children’s bracelets sold at Claire’s stores nationwide. About 19,000 “Best Friends” charm bracelet sets were recalled as the heart lock charms attached to the bracelets contain high levels of cadmium. Toxic if ingested by children, cadmium can cause serious adverse health effects over long term low-level exposure.

The bracelets were sold at Claires from February 2009 to January 2010.

On Wednesday, May 19, Wal-Mart said it would pull a line of Miley Cyrus-brand bracelets and necklaces from the shelves after tests by the Associated Press showed high levels of Cadmium. The statement was issued by Wal-Mart, Miley Cyrus and Max Azria, of women’s fashion line BCBG Max Azria. Azria teamed up with Cyrus to develop an exclusive Wal-Mart line in June 2009.

Cadmium is typically found in the manufacture of pigments and batteries and in the metal-plating and plastics industries, according to the Environmental Protection Agency. Depending upon how it is ingested, a build-up of Cadmium in the system can lead to kidney disease, bronchiolitis, decreased birthweights in babies, and lung cancer. The EPA considers Cadmium to be a probable human carcinogen (cancer-causing agent) and has classified it as a Group B1 carcinogen.
