Advanced wastewater treatment technologies such as bioactivated carbon (BAC) filtration and ozonation are increasingly implemented to remove micropollutants from effluents. Yet their ecological impacts remain insufficiently understood. In this study, we evaluated the chemical and ecological effects of six wastewater treatment scenarios in outdoor freshwater microcosms over 42 days within the BO<s…

• MP concentrations, loads, and yields quantified across five stormwater catchments. • Hydrologic modeling coupled with sediment surveys and particle-mass balances. • Results reported in both particle- and mass-based units. • MP yields resolved by polymer type, size class, and particle shape. • Rubber and sediment yields covaried with MP yields and land use metrics. Urban stormwater runoff is a m…
