In January 2008, the U.S. EPA launched a program that asks industries to submit available information about the nanomaterials that they manufacture or use. The voluntary program, called the Nanoscale Materials Stewardship Program (NMSP), was intended to provide basic information to help guide regulatory decisions. In the 7 months since its launch, 22 companies have reported to EPA, but critics say that the program is creeping along and that the human-health and environmental risks of this rapidly growing technology remain uncertain.
In the meantime, markets are filling up with products made of these small but powerful nanomaterials. From toothpaste to bacteria-free socks, and even including a swimsuit and running shoes used at the recent Olympics in Beijing, there are 803 products that reportedly contain nanomaterials, according to an analysis by the Woodrow Wilson International Center for Scholars’ Project on Emerging Nanotechnologies (PEN), a nonpartisan group.
Despite the promise of nanotechnology improving our lives, the potential risks of the technology remain largely uncertain. While researchers try to bridge the data gap to help risk assessors, experts around the world are emphasizing the need to regulate and oversee manufacturers to minimize potential risks from exposure to nanomaterials in workers, consumers, and wildlife.
