Fate and biological uptake of polystyrene nanoparticles in freshwater wetland ecosystems

Summary

Researchers studied the fate of polystyrene nanoparticles released into freshwater wetland ecosystems using controlled mesocosm experiments. They found that the wetlands effectively retained the nanoplastics, with most particles ending up in sediments while some were taken up by invertebrates and aquatic plants. The study suggests that wetlands may act as natural sinks for nanoplastic pollution, but that organisms within these ecosystems are exposed through biological uptake.
