Cadmium | Toxic Substances | Toxic Substance Portal | ATSDR

Summary: Cadmium is a natural element in the earth's crust. It is usually found as a mineral combined with other elements such as oxygen (cadmium oxide), chlorine (cadmium chloride), or sulfur (cadmium sulfate, cadmium sulfide). All soils and rocks, including coal and mineral fertilizers, contain some cadmium.

Cadmium Toxicity: Where is Cadmium Found?

Cadmium, a rare but widely dispersed element, is found naturally in the environment. Most cadmium ore (greenockite): occurs in association with zinc. It is released into the environment through mining and smelting, its use in various industrial processes, and enters the food chain from uptake by plants from contaminated soil or water.
