Summary

This study found that bioretention cells (green infrastructure stormwater filters) effectively remove microplastics in the 25 to 106 micron size range from stormwater runoff. Bioretention cells represent a promising green infrastructure approach for intercepting microplastics before they reach streams and rivers.
