Cadmium poisoning: causes and symptoms

2021-7-29 · Cadmium is a metal that appears soft, malleable, and bluish-white in its elemental form. While it is a relatively widespread element, it is rarely found on its own as a pure metal and more often forms complex compounds in zinc ores. It is mainly produced through the process of smelting, mining, and refining zinc, lead, and copper.
