The discovery of graphene brought to the development of new and promising materials with an infinite range of applications, recently also in the rubber mix of tyres, asphalt and concrete. This will inevitably cause a release of graphene-related materials (GRMs) in the environment with hardly predictable consequences. My project aims at investigating the effects of GRMs on the sexual reproduction process of seed plants, which is very important from an economic and ecological point of view. Another work will be focused on the ability of rot fungi in the depletion of GRMs.
