Biodegradation and Surface Reconfiguration Triggered the Adsorption–Desorption of Phenanthrene on Biodegradable Polylactic Acid Microplastics in the Marine Environment

Key Points

• The aim is to investigate how biodegradation and surface changes affect the adsorption-desorption of phenanthrene on polylactic acid microplastics in marine settings.
• Examined the effects of biodegradation on polylactic acid microplastics
• Analyzed surface configurations pre- and post-adsorption of phenanthrene
• Assessed adsorption-desorption dynamics in a marine environment
• Biodegradation improved the adsorption of phenanthrene on micoplastics
• Surface reconfiguration significantly influenced desorption rates
• Phenanthrene adsorption showed a variable pattern based on microplastic treatment
