Dozens of new products are created each month through the use of nanotechnology, but there are still many unanswered questions relating to this technology and its effects. Is the nanotechnology industry regulated adequately? How should government be responding? Do we know enough about the potential health risks or environmental damage this technology could cause? During today's OnPoint, Terry Davies, senior adviser at the Project on Emerging Nanotechnologies and a senior fellow at Resources for the Future, discusses his new report which seeks to provide an outline of how U.S. EPA and other federal agencies should revise their regulatory policies relating to nanotechnology. In the report, "EPA and Nanotechnology: Oversight for the 21st Century," Davies says it is imperative that EPA change regulations and laws relating to nanotechnology because of its widespread exposure. Davies, a former EPA assistant administrator for policy, planning and evaluation, also explains why he believes the promise of nanotechnology outweighs the potential risks.
