ClearTransport and retention of microplastic fibers in streams are impacted by benthic algae, discharge, and substrate
Researchers used outdoor experimental streams to measure microplastic fiber transport and retention under varying conditions of benthic algae cover, stream discharge, and substrate size. Higher discharge and algae cover increased downstream transport while coarser substrates and algae promoted retention, showing that biological and physical stream features strongly control microplastic fate in rivers.
A National-Scale Framework for Visualizing Riverine Concentrations of Microplastics Released from Municipal Wastewater Treatment Incorporating Generalized Instream Losses
A modeling framework was developed to predict how microplastics from consumer products flow through wastewater treatment plants and into U.S. rivers, based on WWTP removal efficiency and downstream settling rates. Visualizing these concentration patterns helps identify rivers and communities most at risk from microplastic contamination.
