Synthetic Microfiber Material Influences Ingestion by Freshwater Worms

Plastics enter the environment, amongst others, from synthetic textiles, which shed microplastic fibers (microfibers) during their production, use and disposal. We tested whether short- and long-term effects of microfibers on the aquatic worm, Lumbriculus variegatus , depend on the synthetic microfi...

Description
Summary:Plastics enter the environment, amongst others, from synthetic textiles, which shed microplastic fibers (microfibers) during their production, use and disposal. We tested whether short- and long-term effects of microfibers on the aquatic worm, Lumbriculus variegatus , depend on the synthetic microfiber material. Microcosms containing L. variegatus were exposed to no microfibers (control) or one of three polymer treatments (nylon, polyester, or olefin) at 5 g of microfibers kg -1 of sediment for 48 h or 28 days. Following exposure, L. variegatus were counted, weighed, and the number of microfibers ingested determined. Polyester microfibers occurred in higher quantities (10–12) than nylon and olefin (
