Abstract
Using the core collection of Web of Science and the literature of CNKI as data sources, this study uses the Citespace knowledge map analysis tool to analyze the annual publication volume, author group, publication organization, keyword clustering, and the emergence of heavy metals in Bohai Sea sediments. Then explore the research status, hotspots, and future development trends of heavy metals in Bohai Sea sediments. The organization with the most publications is the Chinese Academy of Sciences. The author with the most publications is Liu Jihua from the Qingdao National Marine Science and Technology Laboratory. The study of heavy metals in Bohai Sea sediments focuses on some areas' spatial distribution, risk assessment, and source analysis. In the future, we will further explore the large-area and long-term spatiotemporal distribution characteristics, quantitative source analysis, and comprehensive evaluation system of heavy metals in Bohai Sea sediments.
