Researchers claim that nanopollution and nanowaste may become a problem as more and more products start using nanotechnology:
The problem researchers have today is determining whether or not nanopollutants behave the same in the natural environment as other common waste products. Andrew Maynard, one of the few advocates for nanotechnology research with regard to occupational health, has issued a call for national awareness of nanotechnology interactions on the nanoproject.org portal. "The good news is that international concern over how to ensure safe nanotech workplaces has resulted in some progress. The bad news is that critical questions about worker safety -- and about broader environmental, human health and safety issues -- remain unanswered," Maynard claims.
Researchers at Rice University Center for Biological and Environmental Nanotechnology are currently investigating possible means of treating nano-waste products before they are released into the environment. While experimenting with fullerenes or buckyballs composed of C60 carbon nanoparticles, researchers found that it was not possible to dispose of nano-waste using traditional means. But never mind attempts at disposal, the few researchers involved with buckyball research are actually still debating on whether or not fullerenes are even hazardous to organisms.
