Nanotechnology: good for golf balls, bad for health? - CTV, Canada
Nanotechnology may help create a new generation of products, but it may also pose risks to the environment and to human health.
Some scientists believe more studies need to be conducted to asses the impact of nanoparticles on human health before they become part of products sold on the mass market.
"We are putting products onto the marketplace and using them and we don't know what their impact will be."

Scientists call for nanotechnology oversight - Delaware Online, USA
Scientists are urging U.S. regulators to regularly screen the health and environmental effects of tiny engineered particles used in more than 800 consumer products, and step up oversight of the nanotechnology industry.
The Food and Drug Administration has moved too slowly, putting the public at risk of exposure to novel materials whose effects aren't well understood, critics said last week at an FDA forum in Rockville, Md. The government has yet to adopt an appropriate strategy to evaluate human exposure to nanoparticles, they said.
