Research Progress and Hotspots on Disposalof Landfill Leachate: A Bibliometric AnalysisUsing Knowledge Mapping Method
Summary
Not relevant to microplastics — this is a bibliometric analysis of landfill leachate treatment research from 1996–2022, tracking publication trends and identifying dominant themes such as membrane bioreactors and advanced oxidation.
Disposal of landfill leachate is a critical environmental challenge due to its high pollution content.Effective treatment technologies are essential to mitigate the adverse impacts on groundwater and surrounding ecosystems.This paper employs bibliometric analysis and utilizes CiteSpace software to conduct a visual analysis of the knowledge graph of 959 research articles on "Disposal of Landfill Leachate" from the Web of Science core database for the period 1996-2022.The results indicate that the publication quantity has undergone three stages: the sprouting stage, the stable development stage, and the rapid development stage.In terms of international collaboration, China and the USA play an absolute core role.The journals Waste Management, Journal of Hazardous Materials, and Water Research are ranked among the top 3 publications in the field of landfill leachate treatment.The keyword co-occurrence clustering analysis revealed 7 clusters, including groundwater quality, heavy metals, hydrogeophysics, municipal solid, hydraulic conductivity, geochemical barriers and waste disposal, representing the primary research topics.This paper provides a comprehensive analysis of the research progress and development trends in the field of disposal of landfill leachate.It contributes to a better understanding of the key research areas and offers potential prospects for future investigations to researchers.
