Fragmentation and abrasion of plastics by sediments and chemical additive leaching

This presentation introduces the PLASTICAL project, which investigates the
fragmentation of plastics during sediment transport and its implications for the release of chemical additives. Using a combination of laboratory-based fragmentation experiments and field analyses in river systems, complemented by marine sampling, we quantify how different transport processes control plastic fragmentation and surface abrasion. By
linking fragmentation dynamics to leaching behavior, the project aims to better
constrain how sedimentary conditions influence additive release. Ultimately, this work improves predictions of microplastic distribution and associated chemical impacts in
environmental systems.
