Abstract Various tiny plastic particles were retrieved from the sea and studied using scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDX) analysis to prepare realistic reference microplastics (MP). Most of the MP exhibited a d

Microplastics (MP) encompass not only plastic products but also paint particles. Marine microdebris, including MP, was retrieved from five sampling stations spanning Nagasaki-Goto island and was classified into six types, primarily consisting of MP (

Abstract The polystyrene (PS) retrieved from the beach exhibited no change in surface texture. In contrast to it, the retrieved polypropylene (PP) had a rumpled surface texture. Highly reactive sulfate radical generated by K2S2O8 was employed as degr

The alteration of an ultraviolet light absorber (UVA: UV-326) in polymers (PP, HDPE, LDPE, PLA, and PS) over time during degradation was studied using an enhanced degradation method (EDM) involving sulfate ion radicals in seawater. The EDM was employ

Marine microplastics (MP) and microdebris were retrieved from the five sampling stations between Nagasaki port and Goto Island and were classified into six types. Three of these types, MP (A), Si-based (B), and Cu-based (C) paint particles, were pred

To establish a marine microplastic (MP) model, the sizes and O/C molar ratios of MP particles retrieved from the sea were measured using scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDX) analysis. Most of the MP particles ex
