Activity in a room stirs up nanoparticles left over from consumer sprays

Researchers from Rutgers University and Xi'an University of Architecture and Technology in China have found that people walking through a space where a consumer product containing nanoparticles was recently sprayed stirred residual specks off carpet fibers and floor surfaces, projecting them some three to five feet in the air. Gediminas Mainelis, the scientist who led this study, said that while it's still too early to gauge the long-term effects of these particles on people's health, the results are important to contemplate. "At this point, it's more about increasing awareness, so that people know just what they are using," he said.
