Roger, The lowest recorded amount of silver to cause argyria, that I have seen, is 900mg over the course of a year orally, which equates to 90 L of 10ppm CS. Another study, as reported by Dr John Hill, estimated that the minimum oral dose for producing argyria is 25 to 50 grams over a 6 month period, which equates to 2,500 to 5000 L. The 900mg result seems to be out of step with all other estimates. Silver Nitrate is soluble in water 222gm AgNO3 per 100gm of water. Silver nitrate solutions contained about 10% AgNO3, this equates to a 37,400 ppm solution as silver, ie 37,400 mg per litre or 37.4 gm per litre. 10 ml of this would supply 0.374 gm of silver! So you can see that not too much of this brew is required to reach the limits as shown above, and of course some people will be more susceptible than others. Not many cases of argyria considering the numbers of people who used these products. Ivan. -- The silver-list is a moderated forum for discussion of colloidal silver.
