The CRC1357 Microplastics at the University of Bayreuth is a large interdisciplinary collaborative research centre funded by the DFG. The speakers are Christian Laforsch (Animal Ecology I) and Andreas Greiner (Macromolecular Chemistry II). This special session highlights new CRC1357 projects results of the main research areas: Biological Effects, Environmental behaviour and migration in and between ecosystems, Mechanisms of degradation of plastics in natural and technical systems. Guest keynote lecturer of the CRC1357 session is Denise Mitrano (ETH Zürich). The special session will be live-streamed on Tuesday 24th November 2020 and available in recorded formats (full session & single talks). 09:00 Christian Laforsch, UBT Welcome & “CRC1357 Microplastics-Fundamental Questions in Microplastics Research” 09:20 Keynote Denise Mitrano, ETH “Small(er) particles, big(ger) problems?
