The European Union Observatory for Nanomaterials (EUON) has published a study that has systematically reviewed and critically assessed the potential health and environmental effects of graphene, graphene oxide, and other two-dimensional (2D) materials, based on existing public information of the last ten years.
It was explained that graphene’s rising popularity and broad application potential raise the need for more efforts in researching its safety aspects. The current study identified potential risks in specific scenarios, for example for surface water and soil located near point sources (such as production sites).
The study, conducted by Innovamol Consulting Srl, Modena (Italy), concludes that cytotoxic effects have been identified for specific graphene and 2D materials both on health and environment. The study report recommends that when health and environmental risks are reported or identified for a specific graphene or 2D material, doses and exposure scenarios should be considered for their manipulation and use.
According to the report, the toxicity and ecotoxicity of graphene-based materials deserve more research efforts using OECD test guidelines and ISO documentary standards. When reporting the results of these tests, a precise description of the material used in the tests is required to enable more specific conclusions on toxicity and ecotoxicity, which currently cannot be generalized.
