This project determined sources and sinks of microplastic in the Warnow river basin, as well as relevant dissemination processes on its way to the open Baltic Sea. Separate models were linked so that the resulting model covers the entire river basin including estuary and coastal waters.

In PLAWES, the modelling system of the German national park Weser-Wadden Sea was the first large European river basin that was investigated in detail regarding its microplastic pollution.

The spread of microplastics in rivers showed that along a given waterway there are sources as well as sinks. Thus, dams and reservoirs constitute important but until now hardly investigated parts of a water system that serve as examples for risk vs. usefulness of sedimentation of microplastics.

Consumers buying products made of or wrapped in plastic play a decisive role in plastic consumption in Germany. A complete avoidance of plastic in everyday life, while unlikely to occur in full, would only be possible with extremely high restrictions. Moreover, many consumers are not aware of how much plastic is put into circulation or into the environment by buying a product.
