中文摘要:

      沉积物重金属污染防治的关键在于识别其污染源，采用铅、锌、镉多元同位素示踪技术是对其进行污染源解析的最佳手段之一。铅同位素示踪技术较为成熟且应用广泛，锌和镉同位素示踪技术作为新兴技术，在重金属污染源解析研究中可作为有力补充。本文系统概述了 Pb-Zn-Cd同位素的示踪机理、组成特征及其在沉积物重金属污染溯源中的应用，提出未来研究工作的重点是采用多元同位素示踪技术，并结合沉积物形态中重金属稳定同位素的组成示踪污染源。

英文摘要:

      Effective prevention and control of heavy metal pollution in sediments necessitates the precise identification of their pollution sources. Among the available methods，the application of lead(Pb)， zinc(Zn)， and cadmium(Cd) isotope tracers stands out as a highly reliable means of analyzing pollution sources.While the Pbisotope tracer technique has been widespread used，the application ofZn andCdiso-topes，as emerging tracers，can substantially enhance the study of heavy metal pollution source analysis. This study offers asystematic exploration of the isotope tracer mechanisms，compositional characteristics， and their application in tracingheavy metalpollution sources in sediments. We propose that future research should focus on employing multi-isotope tracer techniques and integrating the isotopic compositions with sedimentmorphologytofurtherenhancetheprecisionofpollutionsourcetracing.
