Tire wear particles (TWP) are a prevalent form of microplastics (MPs) extensively distributed in the environment, raising concerns about their environmental behaviors and risks. However, knowledge regarding properties toxicity these at environmentally relevant concentrations, specifically role persistent free radicals (EPFRs) generated during TWP photoaging, remains limited. In this study, evolution EPFRs on under different photoaging times adverse effects Caenorhabditis elegans were systematically investigated. The process primarily resulted formation reactive oxygen species (O2•−, ⋅OH, 1O2), altering physicochemical TWP. exposure nematodes to 100 μg/L TWP-50 (TWP with time 50 d) led significant decrease locomotory (e.g., head thrashes, body bends, wavelength) neurotransmitter contents dopamine, glutamate, serotonin). Similarly, expression neurotransmission-related genes was reduced exposed TWP-50. Furthermore, addition free-radical inhibitors significantly suppressed TWP-induced neurotoxicity. Notably, correlation analysis revealed negative between levels nematodes. Thus, it concluded that photoaged induce neurotoxicity by affecting neurotransmission. These findings elucidate mechanisms EPFRs, emphasizing importance considering contributions when evaluating risks associated
