摘　　要：微塑料已经在各种环境介质中被广泛检出,并且可能促进环境中抗生素抗性基因(ARGs)的富集与传播。文章从研究方法、富集效果、富集机制方面综述微塑料富集ARGs的研究进展,发现微塑料对多个环境中ARGs富集现象较明显,同时环境类型、微塑料暴露特征(种类、尺寸、暴露时间、与抗生素的联合作用)等因素对ARGs富集效果具有明显影响。微塑料从不同途径促进垂直基因转移与水平基因转移,实现ARGs富集。未来的研究应深入探讨微塑料对ARGs的富集机制,扩大环境研究范围,以进一步评估微塑料对ARGs的富集作用所引发的环境生态风险。Microplastics have been widely detected in a variety of environmental media. Microplastics may promote the enrichment and spread of antibiotic resistance genes(ARGs) in the environment. The research progress of ARGs enrichment by microplastics was reviewed from the aspects of research methods, enrichment effect and enrichment mechanism. It is found that microplastics has obvious enrichment of ARGs in multiple environments. At the same time,environmental types, microplastics exposure characteristics(type, size, exposure time, combined with antibiotics) and other factors have significant effects on the enrichment of ARGs. Microplastics promote vertical gene transfer and horizontal gene transfer from different ways to achieve ARGs enrichment. Future research should further explore the enrichment mechanism of microplastics on ARGs and expand the scope of environmental research to further evaluate the environmental and ecological risks caused by the enrichment of ARGs by microplastics.
