Human Exposure and Consumption
Silver plays no known natural biological role in humans, and possible health effects of silver are a disputed subject. Silver itself is not toxic, but most silver salts are. In large doses, silver and compounds containing it can be absorbed into the circulatory system and become deposited in various body tissues, leading to argyria, which results in a blue-grayish pigmentation of the skin, eyes, and mucous membranes. Argyria is rare, and although this condition does not otherwise harm a person's health, it is disfiguring and usually permanent. Mild forms of Argyria are sometimes mistaken for cyanosis.

Famous quotes containing the words human and/or consumption:
“It is no small mischief to a boy, that many of the best years of his life should be devoted to the learning of what can never be of any real use to any human being. His mind is necessarily rendered frivolous and superficial by the long habit of attaching importance to words instead of things; to sound instead of sense.”
—William Cobbett (1762–1835)
“What happens is that, as with drugs, he needs a stronger shot each time, and women are just women. The consumption of one woman is the consumption of all. You can’t double the dose.”
—Ian Fleming (1908–1964)
