Summary

Researchers investigated the size-dependent uptake and trophic transfer of fluorescent polystyrene microplastic beads and fragments (0.5 µm and 6 µm) in unicellular freshwater eukaryotes representing lower trophic levels. The study aimed to fill a gap in understanding how microplastics move through the base of freshwater food webs via protozoan and algal intermediaries.

Study Type Environmental

Microplastics (MP) have become a well-known and widely investigated environmental pollutant. Despite the huge amount of new studies investigating the potential threat posed by MP, the possible uptake and trophic transfer in lower trophic levels of freshwater ecosystems remains understudied. This study aims to investigate the internalization and potential trophic transfer of fluorescent polystyrene (PS) beads (0.5 μm, 3.6 × 108 particles/mL; 6 μm, 2.1 × 105 particles/mL) and fragments ( Also see: https://micro2024.sciencesconf.org/559330/document
