Unknowns raise environmental concerns
Abstract:
New uses for the minuscule particles appear weekly, but the actual quantities used are still relatively insignificant. Researchers have time to learn what their impacts on the environment could be before they happen.
"We know that history is filled with things that are produced en masse and integrated into our system," Dr. Goss said. "Most are non-toxic but every now and then we'll have PCBs.
"With nanotech, we have the first chance to actually get in on the ground floor with the new manufacturers (and ask), ‘Can we be green in our approach toward integrating new materials into our lives?"'
