    • Effects of Leachates from UV-Weathered Microplastic in Cell-Based Bioassays 

      Rummel, Christophe Daniel; Escher, Beate I.; Sandblom, Oskar; Plassmann, Merle; Arp, Hans Peter; MacLeod, Matthew; Jahnke, Annika (Peer reviewed; Journal article, 2019)
      Standard ecotoxicological testing of microplastic does not provide insight into the influence that environmental weathering by, e.g., UV light has on related effects. In this study, we leached chemicals from plastic into ...

    • Effects of leachates from UV-weathered microplastic on the microalgae Scenedesmus vacuolatus 

      Rummel, Christoph D.; Schäfer, Hannah; Jahnke, Annika; Arp, Hans Peter; Schmitt-Jansen, Mechthild (Peer reviewed; Journal article, 2021)
      Plastics undergo successive fragmentation and chemical leaching steps in the environment due to weathering processes such as photo-oxidation. Here, we report the effects of leachates from UV-irradiated microplastics towards ...

    • Weathering Plastics as a Planetary Boundary Threat: Exposure, Fate, and Hazards 

      Arp, Hans Peter; Kühnel, Dana; Rummel, Christoph; MacLeod, Matthew; Potthoff, Annegret; Reichelt, Sophia; Rojo-Nieto, Elisa; Schmitt-Jansen, Mechthild; Sonnenberg, Johanna; Toorman, Erik; Jahnke, Annika (Peer reviewed; Journal article, 2021)
      We described in 2017 how weathering plastic litter in the marine environment fulfils two of three criteria to impose a planetary boundary threat related to “chemical pollution and the release of novel entities”: (1) ...
