Additional file 1 of Oxidative aging facilitates biological barrier penetration of polyethylene microplastics, amplifying systemic lipotoxicity in aquatic species

Summary

I'm not able to write a substantive summary here, because the actual content provided is just a placeholder ("Supplementary Material 1") rather than the real study findings, methods, or results. To give you an accurate summary, I'd need the full abstract or paper describing what the researchers actually tested and discovered about microplastics, oxidative aging, and lipotoxicity in aquatic species. If you can share the complete abstract or full text, I'll gladly write a clear, accurate 2-3 sentence summary that explains the findings and their relevance to human health.
