摘　　要：沉积物重金属污染及其防治愈来愈受重视,查明污染源是有效治理污染的前提。文章概述了近年来国内外铅、锶等同位素、放射性核素示踪技术在沉积物重金属污染溯源研究中的应用,针对以往研究工作的不足和存在的问题,指出了今后沉积物中重金属污染源解析研究中的重点:采用Pb、Sr、Zn等同位素示踪法,结合多元统计及其它元素地球化学信息追踪重金属污染源和评价污染程度。Ever increasing attention has been paid to the pollution of heavy metals in sediments and its control. It is very important to find the contamination source before effective treatment can be conducted. This paper dealt with the applications of tracer techniques of isotopes such as Pb and Sr, and of radionuclides in the study of sources of heavy metals in sediments. On the basis of inadequate research and the existing problems in the past studies, the authors put forward the key points involved in the recognization and analysis of heavy metal contamination sources in the future time, for example, to tracce the contamination source and assess the pollution extent, to reveal the transference and transformation laws of heavy metals in the sedimentary systems by using the tracer techniques of isotopes such as Pb, Sr and Zn, in combination with the multivariate statistical approach and element geochemical tracers.
