This study examined the effects of hot high-fat simulants on physicochemical properties microplastics (MPs) from polypropylene (PP)-, low-density polyethylene (LDPE)-, and polylactic acid (PLA)-based single-use food container (SUFC) leachates those aging their immunomodulatory effectors. Scenario studies have demonstrated that MPs were released these three types SUFCs. LDPE- PLA-based SUFCs also cellulose. Among SUFCs, only PP particles exhibited a new absorption peak at 1725 cm-1, which phenomenon may be attributed to presence unstable tertiary carbon atoms. Subsequently, we investigated removing additive both thermal-aged with polystyrene (PS) carboxyl-modified PS (PS-COOH) polymer backbones as reference materials. The findings indicated PS-COOH induced comparable innate immune responses, exhibiting similar size SUFC percolates. Consequently, selected original MPs, respectively, evaluate immunity. results revealed thata protein corona formed particle types, more adsorption observed particles. complex enhanced phagocytosis RAW264.7 macrophages increased expression pro-inflammatory genes NOS2 TNF-α through an actin polymerization cross-linking mechanism. In this study, how affect responses using model system, emphasizing importance comprehensive safety evaluations MPs.
