Microplastics: tiny crustaceans can fragment them into even smaller nanoplastics
2020
Alicia Cabrera Cárdenas
Summary
Researchers discovered that tiny crustaceans can physically fragment microplastics into even smaller nanoplastics through their feeding activity, suggesting that common marine animals may inadvertently accelerate the breakdown of plastic into particles small enough to penetrate cells and tissues.
The discovery that such a common animal can rapidly produce vast numbers of nanoplastics is particularly worrying.
