Abstract：With the increasing severity of global plastic pollution,microplastics,as an emerging environmental contaminant,have become a key focus of global environmental governance.The widespread presence of microplastics in freshwater sys-tems poses significant threats to aquatic organisms and ecosystem health.This paper systematically reviews the research prog-ress on microplastic pollution in freshwater systems,with an emphasis on their sources and distribution characteristics.Further-more,the ecological toxicity of microplastics in freshwater ecosystems and their interactions with coexisting pollutants such as heavy metals and organic contaminants are comprehensively analyzed,revealing the potential environmental risks of micro-plastics as pollutant carriers.Although significant advancements have been made in microplastic detection techniques in recent years,challenges remain in the standardization of detection methods,long-term ecological impact assessments,and pollution control strategies.Based on this,future research directions are proposed,highlighting the critical role of technological innova-tion,policy development,and public participation in microplastic pollution prevention and control,aiming to provide scientific support and practical guidance for the management of microplastic pollution and the sustainable protection of freshwater envi-ronments.
