Hair Silver (Ag) levels have been found to reflect environmental exposure to the element. However, hair is commonly contaminated with Silver from hair treatments such as permanents, dyes, and bleaches.
Silver is not an essential element and is of relatively low toxicity. However, some Silver salts are very toxic.
Sources of Silver include seafood, metal and chemical processing industries, photographic processes, jewelry making (especially soldering), effluents from coal fired power plants and colloidal silver products.
The bacteriostatic properties of Silver have been long recognized and Silver has been used extensively for medicinal purposes; particularly in the treatment of burns. There is much controversy over the long term safety of consumption of colloidal silver. Very high intake of colloidal silver has been reported to give rise to tumors in the liver and spleen of animals (Metals in Clinical and Analytical Chemistry, eds. Seiler, Segel and Segel, 1994). However, these data may not have relevance to the effects of chronic, low level consumption by humans.
