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."
