Summary

This study investigated whether differential scanning calorimetry calibrated with pristine PET can reliably identify and quantify aged, environmentally weathered PET microplastic particles. Because environmental microplastics undergo physical and chemical changes over time, developing analytical methods that accurately characterize aged particles is critical for realistic exposure assessments and pollution monitoring.

PET

The microplastic (MP) pollution is recognised as one of the most challenging problems of the twenty-first century (Born and Brüll in The Science of the total environment 811, 2022). Due to inadequate waste management, plastic waste enters the natural...
