Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Most plants bio-accumulate metal toxins such as Cd and when composted to form organic fertilizers, yield a product that often can contain
