Pollution of antibiotic resistant genes(ARGs)in marine ecosystems is characterized by its concealment and difficulty in governance,posing potential risks to ecology and human health.However,the current researches are most focused on specific marine ecosystems or areas,lacking a comprehensive overview and comparative analysis of ARGs pollution in China's marine ecosystems.The study summarized the presence of ARGs in mangroves,coral reefs,estuaries,and bay ecosystems.It analyzed their major transmission pathways and influencing factors,and discussed the potential ecological risks and assessment methods caused by ARGs.The results indicate that ARGs are ubiquitously presented with exhibit complex compositions in typical marine ecosystems of China.Exogenous inputs are the major driving factors of their prevalence,and the regulatory effects of environmental variables also play an undeniable role.ARGs pose potential hazards to marine ecosystems,however,the current systems for ecological risk quantification are still imperfect.This study provides critical evidence for the comprehensive assessment and effective control of ARG pollution in China's typical marine ecosystems.
