The presence of microplastics in aquatic ecosystems is of increasing global concern. This study investigated ingestion, egestion and acute effects of polyethylene microplastics in Daphnia magna . Fate of regular shaped microplastic beads (10–106 µm) were compared with irregular shaped microplastic f...
