摘　　要：铅污染是对人类健康危害最严重的重金属污染形式之一,并且人为活动引起铅污染问题在日益增多。由于铅的污染来源复杂,准确、快速地识别污染源并弄清其迁移路径是土壤铅污染防治的关键问题。随着稳定同位素示踪技术的快速发展,逐渐成为重金属污染的溯源研究中的一项重要技术。根据铅同位素的地球化学特征,分析了其在示踪土壤重金属污染中的理论基础,以铅同位素的示踪原理与测定方法为切入点,参考国内外大量研究案例,重点论述了铅同位素示踪技术在重金属污染溯源研究中的应用现状、不足,并对今后的发展前景进行了展望。Lead pollution is one of the most serious soil pollution for human health,and lead polution caused by human activities becomes a serious problem currently. Due to its various sources,it is a key task for quickly and accurately identifying pollution source and transaction routine of lead pollution in soils. Moreover,with the rapid development of stable isotopic tracing technique,it has also been gradually applied into source identification of heavy metals pollution. Based on the geochemical characteristic of lead isotope,the theory base of this isotope for soil heavy metals pollution tracing is analyzed.This paper introduced the tracing principle and measurement methods of this technique,the application of lead isotope tracing technique in research of heavy medals pollution sources identification,as well as its shortcomings. And the prospect of applications in the field was also discussed.
