Nanosilver: A new name -- well-known effects
Date:1/31/2011

llic nanoparticles, as silver ions in solution or as precipitated insoluble silver salts. "As far as the environmental effects are concerned, it seems that nanosilver in consumer goods is no different than other forms of silver and represents only a minor problem for eco-systems," says Nowack. What is still to be clarified, however, is in what form the unbound silver is present in the treated water released from sewage works, and what happens to the silver sulfide in natural waters. Is this stable and unreactive or is it transformed into other forms of silver?
