Nanotech's health, environment impacts worry ...(isconnect could undermine public support...)

"Nanotechnology is starting to emerge on the policy agenda, but with the public, it's not on their radar," says Scheufele. "That's where we have the largest communication gap."

While scientists were generally optimistic about the potential benefits of nanotechnology, they expressed significantly more concern about pollution and new health problems related to the technology. Potential health problems were in fact the highest rated concern among scientists, Scheufele notes.

Twenty percent of the scientists responding to the survey indicated a concern that new forms of nanotechnology pollution may emerge, while only 15 percent of the public thought that might be a problem. More than 30 percent of scientists expressed concern that human health may be at risk from the technology, while just 20 percent of the public held such fears.

Of more concern to the American public, according to the Nature Nanotechnology report, are a potential loss of privacy from tiny new surveillance devices and the loss of more U.S jobs. Those fears were less of a concern for scientists.

While scientists wonder about the health and environmental implications of the new technology, their ability to spark public conversation seems to be limited, Scheufele says. "Scientists tend to treat communication as an afterthought. They're often not working with social scientists, industry or interest groups to build a channel to the public," he says.

The good news for scientists, Scheufele explains, is that of all sources of nanotechnology information, they are the most trusted by the public.

"I think the public wants to know more. The applications are out there and that concern gap has to be addressed," Scheufele argues. "The climate for having that discourse is perfect. There is definitely a huge opportunity for scientists to
