摘　　要：微塑料是指存在于环境中粒径小于5 mm的塑料颗粒总称。经过对水环境中微塑料聚集和沉降行为的相关研究报道以及借助Vosviewer工具分析,发现研究热点主要集中在微塑料的来源、聚集过程、沉降机制等方面。通过调研发现,微塑料的聚集和沉降过程受到水环境因素(如水动力学条件、电解质、pH等)和微塑料颗粒特性(如颗粒密度、大小、老化等)影响。通过对微塑料在水环境中的聚集和沉降研究的梳理、归纳和总结,有助于深入了解微塑料在水体中的行为规律,为制定相应的环境保护措施提供科学依据。Microplastics are plastic particles with a particle size of less than 5 mm in the environment.After the research reports on the aggregation and settling behaviour of microplastics in the aquatic environment and the analysis with the help of Vosviewer tool,it is found that the research hotspots mainly focus on the source,aggregation process and settling mechanism of microplastics.It was found that the aggregation and settling processes of microplastics were influenced by the water environment factors(e.g.,hydrodynamic conditions,electrolytes,pH,etc.)and the characteristics of microplastic particles(e.g.,particle density,size,aging,etc.).By sorting out,summarising and concluding the research on the aggregation and settling of microplastics in the aquatic environment,it helps to gain a deeper understanding of the behavioural patterns of microplastics in water bodies,and provides a scientific basis for the formulation of corresponding environmental protection measures.
