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:
“Civilization, for every advantage she imparts, holds a hundred evils in reserve;Mthe heart burnings, the jealousies, the social rivalries, the family dissensions, and the thousand self-inflicted discomforts of refined life, which make up in units the swelling aggregate of human misery.”
—Herman Melville (1819–1891)
“I should like to suggest that at least on the face of it a stroke by stroke story of a copulation is exactly as absurd as a chew by chew account of the consumption of a chicken’s wing.”
—William Gass (b. 1924)
