Hi angelnest.
Your calculations are correct.
I do not know about the accuracy of the thresholds used in Europe. 
I personally think that 8 oz a day of 20 ppm CS for a lifetime is an absurd 
requirement. You might need to take 8 oz a day for a few days to deal with a 
critical condition, but a lifetime......?
I take one ounce of 5 ppm a day divided in several doses, when I need it. 
I do not know of any therapeutic preventive value of CS but if so I would never 
take 8 oz a day.
Regards
Frank

  But Frank...  I think I might be in trouble....

  What about this statement in one of Michael's emails...
  >>>The US-EPA publishes an oral reference dose (RfD) that
  is based on a threshold for certain toxic effects such
  as cellular necrosis. In units of micrograms per kg
  per day and is an estimate of the maximum amount of
  daily silver exposure that is not associated with any
  deleterious effects over a lifetime. Current RfD for
  oral silver exposure is 5 micrograms per kg per day.
  An average (european) 70 kg man: = 350 µg/day>>>

  That means that my 4.8mg-4800mcg daily is about 1500% more than the safe 
daily dose  !!  I'm about 50kg ~105lbs, so I should only be consuming 250mcg, 
right ???

  Or am I missing something ???

  Thanks again,
  Angel

    To convert part per million (by weight) into miligrams in 8 oz. do the 
following:

    One fluid oz.of CS equals about 30 grams.
    8 oz. of CS is therefore 240 grams in which you have 20 ppm.
    The grams of silver contained in your 8 oz,
    20x240/1000000=0.0048 gr or 4.8 miligrams.
    This asumes that the specific gravity of a ppm CS dispersion is 1.00.
    Hope it hels
