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:
“He had discovered a great law of human action, without knowing it—namely, that in order to make a man or a boy covet a thing, it is only necessary to make the thing difficult to attain. If he had been a great and wise philosopher, like the writer of this book, he would now have comprehended that Work consists of whatever a body is obliged to do and that Play consists of whatever a body is not obliged to do.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Daily life is governed by an economic system in which the production and consumption of insults tends to balance out.”
—Raoul Vaneigem (b. 1934)
