Has the problem with organic contamination been resolved one way or another? I remember reading that it can be hazardous to fish?
Personally, I would prefer carbon nanotubes to toxic, rare metals.
Ultimately it depends on what form the nanotubes are in, but I don't want them just going nilly-willy around an environment.
To be fair, you can say this about pretty much anything. But unlike microbeads, which are intended to be flushed, nobody is suggesting that it would be a good idea to release them into the environment.
Very true. I'm surrounded by stainless steel but I don't get chromium poisoning. I'm just worried about side effects, about extra CWNT getting out into the open, like how prescription drugs are appearing in the environment.
