Microplastics (plastic particles < 5 mm) have received increasing attention in recent years due to their wide distribution in the environment. A bibliometric analysis was carried out using Web of Science, with significant contributions being observed by English and French research institutions in the microplastic field. Analysis of keywords revealed that the research hotspots were distribution, abundance, and risks of microplastics in the environment. Microplastics have been detected in water bodies and sediments of seven continents and four oceans. However, meaningful comparisons among studies are difficult due to the inconsistencies in sampling methods and concentration units. Moreover, studies have shown that the chemical composition of microplastics, as well as the pollutants adsorbed onto them, can have negative impacts on marine organisms. It remains unclear whether and how the consumption of aquatic products contaminated with microplastics affect human health. Therefore, it is advised that future research should focus on the transfer, accumulation, and effects of microplastics in the food chain.
近年来，由于微塑料（<5 毫米的塑料颗粒）在环境中广泛分布，引起了越来越多的关注。本研究利用 Web of Science 进行了文献计量分析，发现英、法两国的研究机构在微塑料领域做出了重要贡献。通过对关键词的分析发现，该领域的研究热点为环境中微塑料的分布、丰度和风险。已经在七大洲四大洋的水体和沉积物中检测到了微塑料。然而，由于采样方法和浓度单位的不一致，使得不同研究之间进行有意义的比较变得困难。此外，研究表明，微塑料的化学组成以及吸附在其上的污染物可能对海洋生物产生负面影响。目前尚不清楚食用受微塑料污染的水产品是否以及如何影响人类健康。因此，建议未来的研究应集中在微塑料在食物链中的迁移、积累和影响上。
