Huh? What is this craziness? An I.V. of 1 gram silver produces *mild* argyria in the *most sensitive* individuals? That's a whopping amount of silver -- and it produces mild argyria? Most people using CS wouldn't get 1 gram in their lifetime (hmm, I'd better calculate that out :) [calculating] 25,550 days in a lifetime times 0.00001 grams daily (that's 1 liter/quart of 10 ppm CS if it's absorbed 100%) comes out to about 1/4 gram of silver over a lifetime. Maybe I messed something up, but even if I'm low by a factor of 10, it's only 2.5 grams of lifetime silver. And that would be only if the body stored the silver, which it doesn't (according to tests by Roger Altman). >Lifetime >25 g* ---------------------- = 978ug/day >25,5 50 days >Based on an adult body weight of 70Kg, this corresponds to 14ug Kg/day (978 >ug /day / 70 Kg=14 ug /Kg/day).
