- n. A soft, bluish-white metallic element occurring primarily in zinc, copper, and lead ores, that is easily cut with a knife and is used in low-friction, fatigue-resistant alloys, solders, dental amalgams, nickel-cadmium storage batteries, nuclear reactor shields, and in rustproof electroplating. Atomic number 48; atomic weight 112.41; melting point 320.9°C; boiling point 765°C; specific gravity 8.65; valence 2. See Table at element.

- n. A comparatively rare element related to zinc, and occurring in some zinc ores. It is a white metal, both ductile and malleable. Symbol Cd. Atomic weight 111.8. It was discovered by Stromeyer in 1817, who named it from its association with zinc or zinc ore.

Strohmeyer coined the name cadmium, derived from the Latin word cadmia which means calamine.
The best explanation for the shift to making items that are predominantly cadmium is that Chinese manufacturers needed a cheap alternative to lead – and cadmium prices had plummeted due to excess supplies from the shriveling nickel-cadmium battery market.
Two years after sweeping rules sought to limit lead in children's products, another toxic heavy metal, cadmium, is causing concern.
Even as companies intensify scrutiny of lead in products, cadmium is a newly recognized threat.
Some 55,000 pieces are being recalled for high levels of cadmium, which is toxic if ingested.
The metal jewelry, intended for children, has high levels of cadmium, which is toxic if ingested.
The jewelry was manufactured in China and imported by Rhode Island company FAF, Inc. Some 55,000 pieces are being recalled for high levels of cadmium, which is toxic if ingested.
The move follows an "Associated Press" investigation that found items purchased in New York, Ohio, Texas and California had high levels of cadmium, which is linked to some cancers and other problems in children.
Cadmium sulfide (also called cadmium yellow) is used as a paint pigment.
Nearly the only cadmium mineral known is the sulphide, greenockite, but no deposits of this mineral have been found of sufficient volume to be called cadmium ores.
