Summary

Researchers used metagenomic analysis to investigate how polyvinyl chloride microplastics affect the spread of antibiotic resistance genes in Chinese soils. They found that PVC microplastics significantly influenced soil bacterial community composition and increased the abundance of certain antibiotic resistance genes. The study raises concerns that microplastic contamination in agricultural soils may accelerate the dissemination of antimicrobial resistance.

The widespread prevalence of microplastics (MPs) in the environment poses concerns as they are vectors of antibiotic resistance genes (ARGs). The relationships between antibiotic resistomes and MPs remain unexplored in soil which was considered as the reservoirs of MPs and ARGs. This study investigated the effects of polyvinyl chloride (PVC) MPs on soil bacterial communities and ARG abundance which soil samples sourced from 20 provinces across China. We found that PVC significantly influences soil bacterial community structure and ARG abundance. Structural equation modeling revealed that PVC alters soil characteristics, ultimately affecting soil bacterial communities, including ARG-containing bacterial hosts, and the relative abundance of ARGs. This study enhances our understanding of how MPs influence the proliferation and hosts of ARGs within diverse soil environments, offering crucial insights for future strategies in plastic management and disposal.
