Washington Post:  “What happened when the U.S. cracked down on Chinese imports of children’s toys, jewelry and other items containing lead in 2008?  Chinese manufacturers apparently just swapped out the lead for cadmium, another cheap, dangerous heavy metal.  While various government agencies and Congress debate what’s to be done about the recent influx of children’s jewelry containing cadmium, the presence of which was revealed by an Associated Press investigation released early this week, some major retailers, including Wal-Mart and Claire’s, have summarily removed the goods from their shelves.”
