摘　　要：铅污染已经成为威胁人类健康最严重的重金属污染形式之一,并且随着工农业生产铅污染问题日益突出。铅污染来源复杂,如何准确、快速地识别污染源并弄清其迁移转换机制是土壤污染防治的关键。随着同位素检测技术的快速发展,铅同位素示踪逐渐成为重金属污染溯源研究中的一种重要方法。该文阐明了铅同位素示踪机理和组成特征,参考了国内外铅污染源示踪应用实例,分析了铅同位素示踪技术的应用现状,重点剖析了其迁移速率和迁移路径的机理以及污染程度和污染源的定量解析,最后针对铅同位素示踪技术在土壤重金属污染源解析应用中的不足,展望了其发展前景,以期为铅同位素示踪技术在土壤污染源解析与污染治理方面提供参考。With the development of industrial and agricultural, Pb pollution has become one of the most serious problems jeopardizing human health. Due to complex origins of Pb, to quickly and accurately identify the pollution source and trans-formation mechanism is vital in prevention of Pb pollution in soils. On the other hand, with the development of isotope detec-tion technology, lead isotope has gradually become an important approach to tracing the source of heavy metal pollution. In this paper, the lead isotope tracing mechanism and composition characteristics are elucidated, in addition, numbers of applica-tions, home and abroad, of tracking Pb pollution sources are introduced which reflects the status quo of application of Pb iso-tope tracer technology. Furthermore, the migration rate and migration path are analyzed, as well the degree of pollution and source apportionment. Finally, the problems in the application of Pb isotope tracing technology and its development prospect are reviewed, for the purpose of providing references for research of Pb source apportionment and the application to soil pol-lution control.
