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Pb、Zn同位素的双金属源解析手段是对水系沉积物重金属进行源解析的最佳手段之一.本文系统地阐述了Pb、Zn同位素的示踪机理、分析方法以及Pb、Zn同位素在沉积物重金属污染溯源中的应用,以此分析双金属同位素源解析方法的优缺点及具体运用在沉积物重金属污染研究中的可行性,并针对以往研究中的不足和问题,提出同位素源解析的研究趋势与未来展望,对沉积物的重金属污染防治工作具有重大意义.
The key for preventing heavy metal contamination of sediments is to identify their pollution sources. One of the best ways for heavy metal source apportionment of the sediments in the river system is to use Pb and Zn isotopes. This study elaborates the isotopic tracing mechanism,analytical method of Pb and Zn isotopes,and their applications in identifying the source of heavy metals in sediment. The strength and weaknesss of source apportionment technique in bimetal isotopes and their feasibility in sediment were discussed systematically. This review demonstrated the recent progress in applications of using metal isotopic technique to identify the pollution sources. The results and discussions indicated the great potential on preventing heavy metal contamination by using Pb-Zn isotopes.
