Silver and water: reaction mechanisms, environmental impact and health effects
Seawater contains approximately 2-100 ppt of silver
, and the surface concentration may be even lower. River water generally contains approximately 0.3-1 ppb of silver. The phytoplankton concentration is 0.1-1 ppm (dry mass), leading to a 104
bio concentration factor in seawater. In oyster tissue concentrations of approximately 890 ppm (dry mass) were found.
Dissolved in water silver mainly occurs as Ag+
(aq), and in seawater as AgCl2-
