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:
“No one ever promised me it would be easy and it’s not. But I also get many rewards from seeing my children grow, make strong decisions for themselves, and set out on their own as independent, strong, likeable human beings. And I like who I am becoming, too. Having teenagers has made me more human, more flexible, more humble, more questioning—and, finally it’s given me a better sense of humor!”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 4 (1978)
“The Landlord is a gentleman ... who does not earn his wealth. He has a host of agents and clerks that receive for him. He does not even take the trouble to spend his wealth. He has a host of people around him to do the actual spending. He never sees it until he comes to enjoy it. His sole function, his chief pride, is the stately consumption of wealth produced by others.”
—David Lloyd George (1863–1945)
