Microplastics and nanoplastics in stormwater management engineered porous media systems: a systematic review of their sources, transport, retention, and removal characteristics

Summary

This systematic review summarizes how engineered stormwater systems like rain gardens and biofilters capture and retain microplastics and nanoplastics. The findings show these systems can effectively reduce plastic particles in stormwater runoff, which matters because untreated stormwater is a major pathway for microplastics to enter the rivers and lakes that supply our drinking water.
