I did make a pretty strong claim eh? Ok, let me clarify. There is a great deal of research that silver in ecosystems is dangerous and deadly to certain organisms.

See:

http://www.environmentalhealthnews.org/ehs/news/nanosilver
"In one new experiment, Furgeson, a professor of pharmaceutical sciences, exposed zebrafish embryos to silver nanoparticles in a laboratory, and found that some died and others were left with dramatic mutations.

“Some of the fish became extremely distorted, almost making a number nine or a comma instead of a linear fish,” he said.

The nanosilver caused malformations in their eyes, swim bladders and tails, and some developed fluid around the heart that causes congestive heart failure, according to the study, which was published in August in the nanotechnology journal Small."

"If you start releasing ionic silver, it is detrimental to all aquatic biota. Once the silver ions get into the gills of fish, it's a pretty efficient killer"

Just do a quick google "nanosilver damage lakes"

It is my personal position that...

I will not use a 'new' product UNTIL it has been proven to be 100% safe for the user and the environment. For example, I feel it is irresponsible for GMO organisms to be created and let loose in the environment . Prove they are safe first.

It is for this reason that Nuclear Reactors in Canada use 15 years old components by policy. If they don't have a long history of the products ins/outs they will not use it. It would be too dangerous.

As the data is heavily indicating toxicity of silver nano particles I will not purchase a product that sheds them. Why would I risk damage to the environment AND buy a crappy product that gets worse with time?
