Partitioning of secondary organic aerosol onto nanoplastics leading to hygroscopic partially-engulfed particles
Summary
Researchers found that secondary organic aerosol derived from alpha-pinene partitions onto hydrophobic polystyrene nanoplastics in the atmosphere, forming partially-engulfed morphology particles that exhibit hygroscopic growth. The study reveals that nanoplastics can serve as condensation nuclei for organic aerosol formation, altering both the physical state of plastic particles and their atmospheric water-uptake behaviour.
