If you have concerns about the development of nanotechnology, you might want to keep an eye on the 'partnership' between the chemical industry giant DuPont and Environmental Defense (ED), the New York-based environmental group.

The project, according to a joint media release issued in October 2005 by ED's Fred Krupp and DuPont's Chad Halliday, is to "identify, manage and reduce potential health, safety and environmental risks of nano-scale materials across all lifecycle stages." Once developed, the framework will "then be pilot-tested on specific nano-scale materials or applications of commercial interest to DuPont."

To be fair, ED has flagged concerns about there being inadequate health and environmental assessments of nanotechnologies to date. However, ED hasn't mentioned publicly what they think about DuPont and other companies having products that are already on the market without such assessments.
