Distinguishing realistic environmental risks of nanoplastics by investigating fate and toxicology in real-world scenarios: This project is focused on providing critical information to enhance the environmental risk assessment of nanoplastics, and is based on real-world exposure scenarios. In particular, we will investigate interactions with microorganisms present in natural seawater on the formation of microorg-agglomerates of nanoplastics and how these microorg-agglomerates have different properties and therefore different environmental effects compared to nanoplastic particles. We will investigate how toxic substances associate with microorg-agglomerates and influence where nanoplastics accumulate within test marine environments (mesocosms) and whether the toxic substances are released to fish. Toxicology and effects of nanoplastics in fish and marine invertebrates after ingestion will be studied considering a variety of endpoints with a design that will enable effects to be modelled across concentrations and sizes of nanoplastics. The outcome of this project (RealRiskNano) will be to provide risk assessors with urgently needed information to evaluate the realistic risk that nanoplastics pose in marine ecosystems.
