Graphene could have adverse environmental effects, study suggests

The nanomaterial graphene has potentially adverse environmental and health risks, according to a Swedish review.

A team from Sweden's Department of Energy and Environment looked at the available information on graphene, a one-atom-thick layer of carbon that can be stacked or rolled up, touted as a wonder nanomaterial for electronic devices.

“Considerable” emissions of graphene from electronic devices and composites are possible in future, write the researchers in Human and Ecological Risk Assessment. “There are many risk-related knowledge gaps to be filled,” they add.
