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.
