MikroPlaTaS - Microplastics in Dams and Reservoirs: Sedimentation, Spread, Effects

The spread of microplastics in rivers shows that along a given watershed there are not only sources but also sinks or repositories. Thus, dams and resevoirs constitute important (but heretofore hardly investigated) parts of a water system in the sense that they serve as examples for risk vs. usefulness of sedimentation of microplastics. Biofilms, which grow on microplastics, have a special significance for their transport and sedimentation.

The goals of this project are

  • to identify and characterise microplastic in water and sediment
  • to understand how biofilms form on plastic and how sedimentation occurs on these grown-over particles
  • to record how microplastics affect and are taken up by individual organisms as well as by entire communities in model ecosystems and
  • to synthesise the scientific results and draft practical recommendations based on them.

This synthesis should emphasise identifying pathways to eliminate microplastics and to derive practical measures and risk analyses together with the associated partners.

With contributions from the UFZ and WWU, the project MikroPlaTaS was represented at two scientific conferences last week: The "Umwelt2018" from 09. - 12.09.2018 in Münster and the annual meeting of the German Society for Limnology e.V. (DGL) in Kamp-Lintfort from 10.-14.09.2018.

There, the poster "Biofilme auf Plastikpartikeln und deren Nährwert für das Makrozoobenthos" (Biofilms on plastic particles and their nutritional value for the macrozoobenthos) of Diana Michler-Kozma and Rense Jongsma was honored by the vote of the conference participants as one of the five best posters with the poster price of the DGL.


Sampling on the River Ems and in Bautzen and Quitzdorf completed.

Sampling at the Lippe and the Malter Dam has been completed.
