Manufactured Buckyballs Don't Harm Microbes That Clean The Environment, Study Shows - Science Daily, USA
|
Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment, according to Purdue University researchers. "It's important to look at the entire microbial community when nanomaterials are introduced because the microbes are all interdependent for survival and growth. If we see a minor change in these microorganisms it could negatively impact ecosystems." |
Nanotechnology In The Environment: Making Sure Wonder Materials Don't Become Wonder Pollutants - Science Daily, USA
|
As useful as nanotubes may be, the process of making them may have unintentional and potentially harmful impacts on the environment. Carbon nanotubes are 10,000 times thinner than a human hair, yet stronger than steel and more durable than diamonds. They conduct heat and electricity with efficiency that rivals copper wires and silicon chips, with possible uses in everything from concrete and clothes to bicycle parts and electronics. |

Slow federal action to oversee nanotechnology leaves 'room at the bottom' - Nanotech Project, USA
|
State and local governments often have adopted trailblazing initiatives to address environmental, health and safety concerns in advance or in lieu of federal action. With nanotechnology, an emerging field of science with unknown risks, this practice is continuing, a landmark study has found. In regard to oversight of nanotechnology, Berkeley, CA, has taken the lead by adopting an ordinance that requires handlers of nanomaterials to submit toxicology reports on the materials to the city. |
Elected officials in Cambridge, MA, and Madison, WI, have also begun to look at similar reporting mechanisms.
