摘　　要：为了解铅(Pb)、镉(Cd)同位素在重金属污染源解析应用方面的研究进展及未来发展势态,以Web of Science核心数据库中2008-2021年的相关文献为研究对象,运用CiteSpace软件对文献进行可视化分析。结果表明:2008-2021年国际上本研究领域的英文发文数量呈波动增长趋势,2015年后文献量增长幅度较大。在此期间,国际上本领域的研究大致划分为2个时期:2008-2014年,研究焦点侧重于工业、采矿、冶炼等行业的重金属污染状况研究,主要涉及大气、水体和沉积物(湖泊、水库和河流)等介质的重金属污染源解析;2015-2021年,研究焦点逐渐转向重金属与人体健康领域,重点关注土壤及农作物重金属的污染源解析、食品安全和人体健康风险评价等问题。总体上,Pb、Cd同位素在重金属污染源解析应用方面的研究由单一同位素解析、单一环境介质应用向多同位素联合解析、多介质应用方向发展。Lead(Pb)and cadmium(Cd)isotopes have been widely used in the source analysis of heavy metal pollution in the atmosphere,sediment and soil.In order to understand the research progress and future research trends of the application of Pb and Cd isotopes in the field of heavy metal pollution source analysis,this study took the related literatures in the core database of Web of Science from 2008 to 2021 as the research object,and CiteSpace software was used to draw a knowledge map of this research and make a visual analysis of the literatures.Results showed that the number of international English publications on the topic experienced a fluctuating,increasing trend between 2008 to 2021,and the number of papers increased significantly after 2015.During this period,the international research in this field was roughly divided into two periods:from 2008 to 2014,the research focus focused on the study of heavy metal pollution in industries such as industry,mining,smelting,etc.,mainly involving the atmosphere,water and sediments(lakes,reservoirs and rivers).From^(2)015 to 2021,the research focus gradually turned to the field of heavy metals and human health,focusing on the pollution source analysis of heavy metals in soil and crops,food safety and human health risk assessment.In general,the research on the application of Pb and Cd isotopes in the field of heavy metal pollution source analysis has developed from single isotope analysis and single environmental media application to multi-isotope joint analysis and multi-media extended application.
