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.
Abstract
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 Pb isotope tracer technique has been widespread used,the application of Zn and Cd iso-topes,as emerging tracers,can substantially enhance the study of heavy metal pollution source analysis.This study offers a systematic exploration of the isotope tracer mechanisms,compositional characteristics,and their application in tracing heavy metal pollution sources in sediments.We propose that future research should focus on employing multi-isotope tracer techniques and integrating the isotopic compositions with sediment morphology to further enhance the precision of pollution source tracing.
