Summary
Researchers found that UV weathering of PET microplastics increases their downward mobility in stormwater biofilters undergoing freeze-thaw cycles, as UV exposure creates polar surface groups that decrease hydrophilicity and enhance particle transport.
Polymers
An increase in microplastic weathering under UV lights decreases their surface hydrophilicity by the formation of polar groups and increases their mobility in the stormwater biofilter under freeze–thaw cycles.
