【Objective】 The extensive use of halogenated flame retardants has raised serious ecological and health concerns. Soil as the primary contamination sink for halogenated flame retardants has riased wide concern among many scholars.【Method】To understand the current state and emerging trends in the study of halogenated flame retardants in soil environments, a systematic review was conducted using knowledge mapping tools, VOSviewer and CiteSpace, on 2,259 research articles published between 2008 and 2023 from the Web of Science Core Collection database.【Result】The findings reveal the following: (1) The number of publications on halogenated flame retardants in soil environments has steadily increased in the past sixteen years, with Environmental Ecology as the dominant research discipline. Over the research period, China was the dominant country with the largest number of research publications; (2) Key journals in the field include Science of the Total Environment, Chemosphere, and Environmental Science & Technology, with core authors such as Li Jun, Zhang Gan, and Jiang Guibin forming a closely-knit research network; (3) The content of halogenated flame retardants in the soil of China's economically developed regions, especially the Pearl River Delta, Yangtze River Delta and Bohai Rim region, is significantly higher than that of other regions; (4) Halogenated flame retardants in the environment have led to bioaccumulation and biomagnification, causing adverse effects on organisms; (5) Halogenated flame retardants have been widely detected in human bodies, with dietary intake and dust exposure being the primary routes of human exposure; (6) The migration behavior of emerging brominated and chlorinated flame retardants in the environment and the health risk assessment are current hotspots trends in the current research.【Conclusion】This study conducted a comprehensive bibliometric analysis of research on halogenated flame retardants in soil environments. The environmental behavior and ecological health risks of halogenated flame retardants in soil have been receiving increasing attention, particularly in economically developed regions with severe pollution. Future research should focus on the transformation mechanisms and ecological effects of halogenated flame retardants in complex environmental matrices, especially the long-term effects of some emerging halogenated flame retardants, and provide a scientific basis for more effective management policies.
