Silver (CASRN 7440-22-4)
Some interesting highlights from Environmental Protection Agency...
- "The current RFD for
oral silver exposure is 5 micrograms/kg/day with a critical dose
estimated at 14 micrograms/kg/day."
(Equivalent to 350mcg per day for 150lb adult.) - "Silver compounds have been employed for medical uses for centuries."
- "The oral intake of silver from a typical diet has been estimated to range from 27-88 ug/day (Hamilton and Minski, 1972/1973; Kehoe et al., 1940)."
- "In addition to silver arsphenamine, any silver compound (silver nitrate, silver acetate, argyrol, Neosilvol and Collargol, etc.), at high dose, can cause argyria."
- "No evidence of cancer in humans has been reported despite frequent therapeutic use of the compound over the years."
