Summary

Researchers found that freezing accelerates microplastic degradation in iron-containing anoxic solutions, driven by highly reactive iron(IV) species and hydroxyl radicals generated through freeze-induced concentration of iron cycling reactions.

The Fe( iii )/Fe( ii ) cycle together with newly formed EPFRs and H 2 O 2 can cause microplastic degradation in ice.
