or assimilated into biomass. However, current research exhibits marked methodological heterogeneity, with studies differing in PS substrate forms, experimental designs, and detection endpoints, hindering cross‑study comparison of degradation efficiency. Furthermore, most studies lack standardized validation such as isotope tracing, undermining the reliability and comparability of results. Unified experimental and reporting standards, along with wider adoption of validated methods, are urgently needed to underpin future research and application.
