Overview

Meta-analysis reveals MP biofilms significantly enrich high-risk ARGs in freshwater environments, indicating a potential health risk.

Key Points

  • This research aims to analyze the enrichment of antibiotic resistance genes on microplastics compared to surrounding freshwater environments.
  • Conducted a systematic review and meta-analysis of ARG profiles on microplastics and freshwater environments.
  • Compared ARG enrichment in microplastics biofilms versus surrounding water.
  • Performed subgroup analyses for mobile and enzyme-mediated resistance categories.
  • Significant ARG enrichment found in microplastics compared to surrounding water.
  • Mobile and enzyme-mediated resistance genes preferentially accumulate on microplastics.
  • Non-biodegradable polymers show stronger ARG enrichment than biodegradable ones.
