文摘

We performed the first modeling study on the fate of nanoplastic and microplastic in rivers. The fate and retention of e.g. tyre dust or cosmetics ingredients can be simulated. Aggregation-sedimentation and Stokes settling drive the retention in rivers. Particle size affects retention, and location of accumulation hot spots in sediment. River hydrodynamics has profound implications for the emission of plastic to sea.
