Summary

Researchers used carbon-14 radiotracers to study the phototransformation of polystyrene nanoplastics in water versus air, finding that aqueous conditions promoted both mineralisation and photo-oxidation with significant leaching of carbon from the particles. The results demonstrate that the environmental matrix strongly influences the fate and breakdown rate of nanoplastics.

PS

A carbon-14 radiotracer-based study revealed that water promoted mineralization and photo-oxidation of polystyrene nanoplastics with significant amounts of carbon leached out.
