The pervasive presence of antimicrobial resistance (AMR) in various ecosystems threatens global health, especially persistent biofilm states. Both anthropogenic and natural surfaces environments provide ideal habitats for development. Microplastics (MPs), as emerging rapidly proliferating pollutants, are particular concern due to their unique physicochemical properties ubiquity across environments. However, it remains unclear whether biofilms on MPs pose a higher AMR risk compared with surfaces. Here, we employed an integrative approach combining phenotypic genotypic analysis via single-cell spectroscopy high-throughput quantitative PCR systematically compare risks 5 (polyethylene, polystyrene, poly(vinyl chloride), polylactic acid, Tetra Pak) 3 (wood, rock, glass) urban aquatic ecosystem. Our results revealed that harbored proportion metabolically active antibiotic-resistant bacteria more high-risk antibiotic genes than By incorporating three additional biofilm-related factors, including biomass, microbial activity, pathogen abundance, the health was quantified found be highly dependent surface types. exhibited, average, 10-fold A structural equation model further identified hydrophobicity diversity pivotal factors determining different This systematic comparison provides new insights into real-world environmental impact pollution underscores necessity integrating plastic control management strategies.
