I have seen the following repeated on many websites: The World Health Organization's "Guidelines for Drinking Water Quality" states, "It is unnecessary to recommend any health-based guidelines for silver as it is not hazardous to human health."
This is a direct quote, and I'd love to have the page number without (a) buying the book, and (b) searching through the entire volume for that one sentence. Also, there are several editions of the WHO book. Who knows if that passage on silver has been taken out in newer editions? Thanks in advance for your help. Nenah
