铅同位素特征值法在土壤源解析中的应用

Application of Lead Isotope Signature in Soil Source Apportionment

随着工农业的快速发展,导致不同来源的铅不断释放进入土壤,土壤铅污染已成为了土壤污染中亟待解决的问题之一,污染来源的示踪以及污染物的定量源解析是土壤污染防治的重要一环。近年来,国内外研究表明,铅同位素特征值法是土壤铅污染定量源解析的重要方法之一,并已在土壤铅污染定量源解析中得到了较广泛的应用。概述了铅同位素定量解析的方法原理以及国内外研究现状与进展,并通过文献调研构建了国内部分省市铅同位素特征值指纹库,以期为研究者在探究所在区域主要铅污染源及其贡献率时提供一定的参考,最后针对铅同位素特征值法在土壤铅污染定量源解析应用中的局限性提出了展望。

With the rapid development of industry and agriculture,lead from different sources is continuously released into the soil,and soil lead pollution has become one of the problems that need to be solved in soil pollution.Tracing of pollution sources and quantitative source analysis of pollutants are an important part of soil pollution prevention.In recent years,studies at home and abroad have shown that the lead isotope ratio method is one of the important methods for the analysis of quantitative sources of soil lead pollution,and has been widely used in the analysis of quantitative sources of soil lead pollution.This paper describes the principle of quantitative analysis of lead isotope and the current status and progress of the research on the application of this method at home and abroad,and a fingerprint library of lead isotope ratios in some provinces and cities in China was constructed through the method of literature research,in order to provide researchers with a certain reference when exploring the main lead pollution sources and their contribution rates in the area.Finally,some prospects are put forward for the limitation of the application of lead isotope ratio method in the analysis of quantitative sources of soil lead pollution.
