    Abstract:

    [Objective] This work was performed to understand the research status, hot spot and development trend on remediation of heavy metals in agricultural soils all over the world. Meanwhile, it could objectively reflect the academic level and international influence of relevant countries, institutions and scholars, etc. in this field.[Method] We employed the Web of Science core collection database(WoS), together with the analysis tools self-provided by WoS, HistCitecitation analysis software and VOSviewer software to conduct bibliometric analysis of the literatures on immobilization of heavy metals in agricultural soil.The data were retrieved from the literatures published during the period of 1990-2019.[Result] Results showed that a total of 3376 articles related to immobilization/stabilization of heavy metal pollution in farmland soil were retrieved, and the quantity of publications increased steadily year by year worldwide. The top three countries in number of publications are China, the United States and Spain, and China ranks first in volume of publications, accounting for 28.79%.The Chinese Academy of Sciences, Consejo Superior de Investigaciones Cientificas, University of Florida and Zhejiang University are the major paper-publishing institutions, which have remarkable scientific research level and influence in this field. Particularly, Chinese Academy of Sciences has the highest number of publications and citation frequency, publishing 224 articles with total local citation score 1276 times. Major publishers include Environmental Science and Pollution Research, Chemosphere, Science of the Total Environment, Journal of Hazardous Materials, etc. The passivants include mainly sludge, biochar, red mud, compost, phosphate, lime, and etc. And the research on metal immobilization/stabilization in agricultural soils mainly focuses on the bioavailability of heavy metals. Cadmium, lead, copper, zinc and arsenic are the main concerned heavy metals.[Conclusion] This study would help researchers in this field to grasp the development trend and hotspots accurately, and provide important insights and references for future research.
