One statement was a half criticism, stating that for some reason, whenever someone asked about toxicity, the reply always focused on graphene in finished goods like tennis rackets, and no one ever examined the toxicity of graphene apart from the object it's used to create.
There was something sneaky about the article and the 'expert' talked sideways a lot and said we're just now turning our attention to the issue. So I went and found an article from decades ago that had been purged (below). As always, they knew about it but with such control through purging/canceling, all things become 'new'.
Somehow the universities were not able to strip of funding or otherwise prevent an environmental graphene toxicity study from occurring, so they just deleted it.

Material that could change electronics industry is shown to be very mobile in water and likely to cause negative environmental impacts if spilled
RIVERSIDE, Calif. (www.ucr.edu) — In a first-of-its-kind study of how a material some think could transform the electronics industry moves in water, researchers at the University of California, Riverside Bourns College of Engineering found graphene oxide nanoparticles are very mobile in lakes or streams and therefore likely to cause negative environmental impacts if released.
Graphene oxide nanoparticles are an oxidized form of graphene, a single layer of carbon atoms prized for its strength, conductivity and flexibility. Applications for graphene include everything from cell phones and tablet computers to biomedical devices and solar panels.
The use of graphene and other carbon-based nanomaterials, such as carbon nanotubes, are growing rapidly. At the same time, recent studies have suggested graphene oxide may be toxic to humans.
As production of these nanomaterials increase, it is important for regulators, such as the Environmental Protection Agency, to understand their potential environmental impacts, said Jacob D. Lanphere, a UC Riverside graduate student who co-authored a just-published paper about graphene oxide nanoparticles transport in ground and surface water environments.

The paper co-authored by Lanphere, “Stability and Transport of Graphene Oxide Nanoparticles in Groundwater and Surface Water,” was published in a special issue of the journal Environmental Engineering Science.
