Medicine
In medical usage, heavy metals are loosely defined and include all toxic metals irrespective of their atomic weight: "heavy metal poisoning" can possibly include excessive amounts of iron, manganese, aluminium, mercury, cadmium, or beryllium (the fourth lightest element) or such a semimetal as arsenic. This definition excludes bismuth, the densest of approximately stable elements, because of its low toxicity.
Minamata disease results from mercury poisoning, and itai-itai disease from cadmium poisoning.
