Scientometric analysis and scientific hotspots on microplastics/antibiotics interaction
Summary
This scientometric analysis mapped the research landscape on microplastic-antibiotic interactions using bibliometric methods, identifying growth trends, key journals, and emerging hotspots including plastisphere ecology, antibiotic resistance gene dissemination, and combined ecotoxicology.
In recent years, the interaction of microplastics and antibiotics has been a hot spot and attracted researchers’ attention. However, the comprehensive research status and development trends in this field are not clear and sufficient. In this study, the hot topics and trends of microplastics/antibiotics interaction were conducted by bibliometric visualization analysis. A total of 546 articles were obtained from Web of Science (WOS) during 2008–2023, with “microplastics” and “antibiotics” as the topics. The results show that the number of publications on microplastics/antibiotics interaction has been increased continually from 2008 to 2023. However, research on the topic is almost none from 2008 to 2015. China is at the top with 393 publications, and the top 10 universities and research institutions are all from China, reflecting the important contribution of Chinese researchers in this field. Nearly 40 % of these articles in the field have been published in authoritative journals of Science of the Total Environment , Journal of Hazardous Materials and Environmental Pollution , in which five of the top 10 cited papers were published in Environmental Pollution . By co-occurrence and clustering analysis of keywords, the research hotspots focused on the impact of microplastics on antibiotic resistance genes in environments, the adsorption of microplastics on antibiotics, and the ecological effects of microplastics/antibiotics combined exposure can be displayed. The scientific conclusions obtained here will assist in understanding the current research and developing trends of the microplastics/antibiotics interaction deeply and systematically, and provide further research directions for scholars. • A total of 546 articles were obtained from Web of Science (WOS) during 2008–2023, with “microplastics” and “antibiotics” as the topics. • The number of publications has been increased continually from 2008 to 2023, and China is at the top with 407 publications. • Nearly 40 % of the articles in the field of microplastics/antibiotics interaction have been published in authoritative journals of Science of the Total Environment , Journal of Hazardous Materials and Environmental Pollution. • The scientific conclusions obtained are helpful to understand the current research and developing trends of the microplastics/antibiotics interaction, and they will provide further research directions for scholars.
