Siver nanoparticles are not harmful to fish

Abstract:
Scientists have found that tiny silver nanoparticles floating in rivers may not be as damaging to fish as previously thought.

Nanosilver kills the microbes that produce nasty smells and it is now widely used in t-shirts, socks and many types of sports clothes. But when these high-tech outfits go in the washing machine, the nanosilver is washed out and ends up in our rivers.

'Although silver can cause harmful effects at high exposure levels, it is not especially toxic to humans or other mammals,' says Professor Charles Tyler, from the University of Exeter. But for fish, it's a different story. Silver has a strong toxic effect on fish - it interferes with the way fish regulate the balance of ions in their cells.
