Abstract

This research investigates the long-term degradation of microplastics in marine environments. The study reveals significant degradation of plastic surfaces and bulk phases varying by time and polymer type. Biofouling, altered surface morphology, thermal stability changes, and chemical signature shifts were observed. Secondary micronanoplastics were formed, with degradation rates up to 12 times higher than previous estimates. This time-series data is crucial for developing plastic-specific risk assessments and informing plastics policy.
