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 an accurate summary of this paper's findings, because the text provided is only a supplementary materials file, not the actual research paper with its methods and results. Supplementary files typically contain extra data tables, figures, or technical details meant to accompany the main study. To give you a reliable, plain-language summary, I'd need the full text or abstract of the primary research article—the one that explains what the researchers actually tested and found regarding how "oxidative aging" (chemical breakdown from exposure to sun, heat, or water over time) affects microplastics' ability to cross biological barriers, like the gut lining, in aquatic
