Mechanical fragmentation and residence dynamics of textile polyester microplastics in a freshwater bivalve

Microplastics 2026
Maria Fernanda Rosa, Walter R. Waldman

Summary

This study examined how freshwater bivalves mechanically fragment and process textile polyester microplastic fibers, tracking fiber depuration through fecal output over time in a bioaccumulation experiment. Understanding how bivalves interact with textile microplastics is critical for assessing their role as bioindicators and quantifying microplastic transfer through freshwater food chains.

Study Type Environmental

Photos: Textile polyester microplastics offered to freshwater bivalves in a bioaccumulation study. These photos show the depuration of the fibers found in the feces over the days.
