Guidelines for Canadian Drinking Water Quality: Guideline Technical Document – Silver

Silver, a white, lustrous, malleable metal, has the highest known electrical and thermal conductivities of all metals. Silver occurs in nature in elemental form and in ores such as argentite (Ag2S), horn silver (AgCl), proustite (Ag3AsS3), and pyrargyrite (Ag3SbS3). In the Earth's crust, it is generally found at concentrations of the order of 0.1 mg/kg.
