Cadmium: biological information

Biological role of cadmium: cadmium might be a necessary element in very, very, small quantities in rats.

Inhalation of cadmium dust causes problems for the respiratory tract and for the kidneys. Death may follow. Ingestion of any significant amount of cadmium causes immediate poisoning and damage to the liver and the kidneys.

Levels in humans

Hazards and Risks

Hazards and risks associated with cadmium: cadmium compounds are encountered relatively rarely by most people. All cadmium compounds should be regarded as highly toxic. It is a cumulative poison and causes renal failure. Cadmium compounds are carcinogenic and may be teratogenic. Alarmingly, the British Pharmaceutical Codex from 1907 indicates that cadmium iodide ("cadmii iodidum", CdI2) was used as a medicine, "for application with friction to enlarged joints, scrofulous glands, and chilblains".
