Nanotechnology risks unknown
From The Washington Post:
The United States is the world leader in nanotechnology -- the newly blossoming science of making incredibly small materials and devices -- but is not paying enough attention to the environmental, health and safety risks posed by nanoscale products, says a report released yesterday by the independent National Research Council.
[snip]"There is some evidence that engineered nanoparticles can have adverse effects on the health of laboratory animals," the congressionally mandated report said, echoing concerns raised by others at a House hearing last week. Until the risks are better understood, "it is prudent to employ some precautionary measures to protect the health and safety of workers, the public, and the environment."

About 300 consumer products already contain nanoscale ingredients, Maynard said, including several foods and many cosmetics, with little or no research to document their safety.
