Hi Terry: The most predominant cause of argyria is actually fine silver particles, taken in through the lungs via environmental/industrial exposure ( silver mines, metal smithing, ect. ).
The literature tends to focus on "medicinal" silver preperations because these were used/experimented with for medical purposes, but the fact of the matter is that there were thousands of cases of argyria and silver poisoning caused by prolonged inhalation of particles ( not as in EIS, but rather, extremely fine silver dust ).
