Cadmium is a silvery metal that is a byproduct of the refining of zinc, copper and lead. It is mainly used in batteries, solder, and plating of metal, but recent tests have shown that cadmium is used in jewelry imported for children. This jewelry for little girls is mainly imported from China.
There are some cadmium in cigarettes, and some in the ground, but this new danger to children should be avoided, since cadmium accumulates in the body like lead poisoning, and the results are much more severe.
