Microplastics (MPs) have generated worldwide attention due to their global distribution in the environment, and their potential harmful effects on human and animal health. To analyze MPs-related scientific publications from a global point of view, we created a bibliometric profile, by searching the Web of Science Core Collection database for the topic “microplastic* or (micro near/1 plastic*)”, in publications dated from 2004 to 2019. The results revealed an increasing trend in publication output, and identified contributions of different countries and their collaborations, as well as influential authors and productive journals in the field of MPs research. Using co-citation network analysis in VOSviewer, we mined cited references for knowledge bases about analytical methods, potential sources and spatial distributions of MPs, the impacts of MPs on organisms, and the interaction of MPs with contaminants, as well as microorganisms. We also identified four global hotspots for MPs related research, using author keywords co-occurrence network analysis of all extracted publications, as well as Essential Science Indicators highly cited papers from Clarivate Analytics. Results of this study provide a valuable reference for ongoing MPs-related research, which may be of intrigue and awesome noteworthiness for relevant researchers.

2004年至2019年全球微塑料研究的文献计量概况。

微塑料（MPs）由于其在环境中的全球分布及其对人类和动物健康的潜在有害影响而引起了全世界的关注。为了从全球的角度分析与MPs相关的科学出版物，我们通过在Web of Science核心文献数据库中搜索主题为“ microplastic *或（micro near / 1 plastic *）”的出版物，创建了文献计量学概况2004年至2019年。结果揭示了出版物产量的增长趋势，并确定了不同国家的贡献及其合作，以及MPs研究领域的有影响力的作者和生产性期刊。在VOSviewer中使用共引网络分析，我们从引用的参考文献中获取了有关MP的分析方法，潜在来源和空间分布的知识库，MP对生物的影响，以及MP与污染物以及微生物的相互作用。我们还使用所有提取的出版物的作者关键词共现网络分析，以及来自Clarivate Analytics的Essential Science Indicators被高度引用的论文，确定了MP相关研究的四个全球热点。这项研究的结果为正在进行的MP相关研究提供了有价值的参考，对于相关研究人员而言可能是令人着迷且令人敬畏的。
