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.

Famous quotes containing the word medicine:
“We gave ‘em wings to fly and they rained death on us. We gave ‘em a voice to be heard around the world and they preach hatred to poison the minds of nations. Even the medicine we gave them to ease their pain is turned into a vice to enslave half mankind for the profit of a few. Ah, Janet, dear, don’t you see? Every gift that science has given them has been twisted into a thing of hate and greed.”
—Karl Brown (1897–1990)
“Good medicine is bitter to the taste.”
—Chinese proverb.
“We have to ask ourselves whether medicine is to remain a humanitarian and respected profession or a new but depersonalized science in the service of prolonging life rather than diminishing human suffering.”
—Elisabeth Kübler-Ross (b. 1926)
