Microplastics (MPs) carry and spread environmental pollutants far and wide. The surface structure of MPs changes when MPs are exposed to light, and which influences the adhesion of MPs to pollutants. In this study, ultraviolet (UV) irradiation (1000 W mercury lamp, 80W/cm2) was utilized to simulate the aging of PVC MPs in natural environments. The adsorption and desorption behaviors of PVC MPs on tildipirosin were investigated. Furthermore, Escherichia coli was used for antibiotic stress experiments. The results revealed that aged PVC MPs exhib...
