— Researchers have found that a type of buckyball—a carbon nanoparticle that shows
promise for electronic, commercial and pharmaceutical uses — can cause significant
brain damage in fish. The small preliminary study, the first to demonstrate that
nanoparticles can cause toxic effects in an aquatic species, could point to potential
risks in people exposed to the particles, they say. The study was described today
at the 227th national meeting of the American Chemical Society, the world's largest
scientific society.
"There are many potential benefits of nanotechnology, but its hazards and risks
are poorly understood. This study gives us additional cause for concern," says
study leader Eva Oberdörster, Ph.D., an environmental toxicologist with Southern
Methodist University in Dallas.
