Researchers from the University of Edinburgh have been studying health effects of Graphene, and they say that graphene nanoplatelets could post health risks as they can accumulate in the lungs and cause damage.

They say that the nanoplatelets behave like tiny frisbees and stay airborne, and when inhaled they can dig deep into lungs (more so than other graphene forms, anyway). This means that people that work or produce graphene at at risk.

Prof Ken Donaldson, chair of respiratory toxicology at the University of Edinburgh said that further work is needed to actually understand the potential hazards of these nanoplatelets, and to device health and safety measures in manufacturing environments.
