| 摘 要： | 不同源区铅同位素的组成不同,因此可以利用铅同位素的这种"指纹"特征来示踪铅的不同源区。近年来铅同位素示踪在研究土壤中相关重金属来源及其运移途径起到独特的作用。由于铊和铅具有相似的地球化学性质,并且在云浮硫铁矿区污染土壤中其分布与铅有很好的相关性,笔者利用铅同位素作为示踪工具探讨了土壤中铊的污染特征,初步研究表明铊污染物主要累积在土壤深度0~16.5cm范围内,深度为16.5cm以下土壤受到废渣中铊污染的影响较小,但废渣周围土壤深度约44cm范围已经受到来自废渣中铊的影响。 |

| Abstract: | The environmental pollutant has the same lead isotope composition as its source, and hence we can determine the accurate contaminative source through the study of lead isotope composition. In recent years lead isotope tracing has been playing its unique role in studying the source and migration of heavy metals in soil. As Tl and Pb have similar geochemical characteristics, the distribution and migration of Tl in the surface soil of the Yunfu pyrite mine have good correlation with Pb. In this study, therefore, the element and lead isotope tracing was used to study the migration of thallium in soil. Element and lead isotope tracing shows that thallium pollutants are mainly accumulated in top soil of about 0 - 16.5 cm, and that the soil is subjected less pollution in deeper soil. The soil around the slags at the depth of some 44 cm is affected by Tl leaching from the slags. |
