摘　　要：Microplastics(MPs)in aquatic environments easily support biofilm development,which can interact with other environmental pollutants and act as harbors for microorganisms.Recently,numerous studies have investigated the fate and behavior of MP biofilms in aquatic environments,highlighting their roles in the spread of pathogens and antibiotic resistance genes(ARGs)to aquatic organisms and new habitats.The prevalence and effects of MP biofilms in aquatic environments have been extensively investigated in recent decades,and their behaviors in aquatic environments need to be synthesized systematically with updated information.This review aims to reveal the development of MP biofilm and its interactions with antibiotics,ARGs,and pathogens in aquatic environments.Recent research has shown that the adsorption capabilities of MPs to antibiotics are enhanced after the biofilm formation,and the adsorption of biofilms to antibiotics is biased towards chemisorption.ARGs and microorganisms,especially pathogens,are selectively enriched in biofilms and significantly different from those in surrounding waters.MP biofilm promotes the propagation of ARGs through horizontal gene transfer(HGT)and vertical gene transfer(VGT)and induces the emergence of antibiotic-resistant pathogens,resulting in increased threats to aquatic ecosystems and human health.Some future research needs and strategies in this review are also proposed to better understand the antibiotic resistance induced by MP biofilms in aquatic environments.
