The following info would mean you would need to consume 3.8 grams of colloidal/nano silver particles a day to get hope to get argyria from CS..
Quoting from Alexander G. Schauss, Ph.D. (John Hopkins University)
“…you should be advised that we recently completed an extensive review of the scientific literature on the safety of silver, especially as it relates to its one known potential side effect, namely, Argyria. Argyia is an irreversible discoloration of the pigment (skin) caused by excessive silver intake or chronic exposure to silver by certain tissues. The amount of silver required to develop Argyria is estimated to be 3.8 grams per day. By comparison standard 10 ppm colloidal silver contains silver in amounts equaling less than 1 milligram of silver (1,000 micrograms = 1 milligram; 1,000 milligrams - 1 gram), which therefore represents an amount approximately 1/500th to 1/1000th of the amount of silver considered to be a risk in the development of Argyria.
Most cases of Argyria reported in the medical literature over the last 100 years involved chronic intravenous or intramuscular use of the silver preparations, most often involving a silver drug prescribed by physicians which in most cases contained silver nitrate. Other cases of Argyria reported in the medical literature involve application of silver preparations used for many months or years in the treatment of the eye or vagina for certain diseases. We could not locate a single case of orally consumed colloidal silver manufactured in the last 25 years causing Argyria in our review of the literature. This is probably due to the low levels of silver contained in such preparations, since only very small amounts of silver are needed for its antiseptic effect. Humans consume approximately 100 micrograms of silver every day in the diet. Additional amounts within this range would be considered safe by all reasonable estimates, especially if the amount needed to develop Argyria would be equivalent of 380,000 micrograms (or 3.8 grams) of silver a day.
As for the efficacy of silver preparations, we found considerable scientific evidence published over the last 75 years that a number of silver compounds can be effective germicidal (antiseptic) agents against several hundred pathogenic organisms. However, silver is not termed an antibiotic as some have claimed because an antibiotic by definition is derived from a living organism.

The only negative effect reported by CS users is a phenomenon called the “Herxheimer effect”, named after doctor Karl Herxheimer (who identified this phenomenon). Sometimes, when a person starts off for the first time ingesting a large amount of CS, the CS is so efficient at killing pathogens in the body that the body cannot adequately dispose of the dead pathogens through the normal eliminative organs, and it resorts to the secondary ones, the lungs, sinuses and skin. Or the CS user may experience diarrhea, as the body tries to flush itself out. In that case, one merely needs to reduce or temporarily stop the CS until the healing crisis is over, and then start taking smaller amounts of CS. A new European Union
Drinking Water Standard in draft form has removed any limitations on silver in drinking water following the World Health Organization’s “Guidelines for Drinking Water Quality” which states, "It is unnecessary to recommend any health-based guidelines for silver as it is not hazardous to human health." According to the U.S. Environmental Protection Agency (EPA) Poison Control Center, CS is considered harmless. Dr. Samuel Etris, a senior consultant at the Silver Institute, says there has never been any allergenic, toxic or carcinogenic reactions to CS. The U.S. Government’s Center for Disease Control confirmed that fact in 1995.
The term Argyria describes the condition of a bluish gray color of the skin, and Argyosis the bluing of the eye white, resulting from the use of SILVER COMPOUNDS. To better understand the misconception regarding Argyria, I will quote from the book "The Micro Silver Bullet”™ by Dr. M. Paul Farber 1996 page XII (ISBN 1-887742-00-X) In reference to a "Journal of American Medical Association" article, October 18 1995, volume 274 # 15, where cases of Argyria were cited to have been caused by silver compounds (not colloidal silver, but silver mixed with other metals), note: "These Case history resentations represent biased and unprofessional writing. The author's apparent inability to understand the difference between a silver nitrate, sulfide, or other silver compound demonstrates their lack of understanding of basic chemical properties. The matrix, substrate, and particle size are all critical to the varied functions and reactions with use of these products. That is why there has not been a single case of Argyria from a properly manufactured modern-day colloidal silver product. The cases of Argyria reported in the 1920's and 1930's resulted because the technology of the day was unable to produce a pure colloidal silver product with a small enough particle size." Ref. (4-A) The reported cases of Argyria usually involved very high and frequent doses over extended periods of time of silver salts/compounds such as silver sulfate, silver nitrate, silver chloride, etc.
