Cadmium (Cd) Toxicity: Where is Cadmium Found? | ATSDR

Dec 10, 2013· Cadmium is mined and then released into the environment mainly through the air during smelting. Once in the environment, cadmium moves easily through the soil and is taken up into the food chain. Certain plants, such as tobacco, rice, other cereal grains, potatoes, and other vegetables, take up cadmium from the soil.
