The heavy metals most often implicated in human poisoning are lead, mercury, arsenic, and cadmium.
Heavy metal poisoning is the toxic accumulation of heavy metals in the soft tissues of the body.
Cadmium is one thing that is poisonous.
Because exposure to heavy metals is often an occupational hazard, protective clothing and respirators should be provided and worn on the job.
The treatment for most heavy metal poisoning is chelation therapy. A chelating agent specific to the metal involved is given orally, intramuscularly, or intravenously.
