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."

 Silver is
found in human diet ..."up to 88 µg/day (Kehoe et al., 1940)." - U.N. World Health Org Common foods
contain
silver: Wheat flour, bran, meat, ... "several hundred
milligrams per kilogram, have been recorded in mushrooms"
- Health Canada "Nanosilver
has
developed as a potent antibacterial, antifungal, anti-viral and
anti-inflammatory agent. ... The targeting of cancer cells using silver
nanoparticles has proven to be effective"
- Pub Med, NIH.gov - Nov-Dec 2009 "[silver
colloid nanoparticles] showed
high antimicrobial and bactericidal
activity ... including
highly
multiresistant strains ... A very low
concentration of silver (as low as 1.69 mug/mL Ag) gave antibacterial
performance."
- Pub Med, NIH.gov - August 2006 "Silver
is a disinfectant for
non-spore forming bacteria at concentrations about 1000 times lower
than the levels at which it is toxic to mammalian life. ...The ionic
form of silver is necessary"
