Sediment-Water Interfaces as Traps and Sources of Microplastic Fragments and Microfibers─Insights from Stream Flume Experiments

Researchers used controlled stream flume experiments to study how microplastic fibers and fragments settle into riverbed sediments. They found that lower water flow speeds caused faster deposition, with the effect being strongest for fibers, and that traditional settling equations significantly underestimate how microplastics actually behave near the streambed. The findings improve our understanding of where and how microplastics accumulate in rivers.
