| The Environmental Impact of Thallium Sulfide Resource Exploitation in Western Guangdong:An Element and Lead Isotopic Tracing Study |
| The contents of thallium(Tl)and lead(Pb)as well as Pb isotopic composition were analyzed to trace the distribution of natural and anthropogenic Tl in soil of an industrial pyrite slag disposing area from the Yunfu pyrite mine in western Guangdong Province.Soil samples were collected from a soil profile adjacent to a large open disposal pile of industrial Tl-rich pyrite slag and from a similar profile in the background area.The results show that Tl contamination of the soil derived from slag is generally limited and slag-Tl is mainly accumulated in the upper part (0～16.5 cm) of the vicinal soil of the slag pile and show considerable variation in concentration between different sampling sites. As for the concentration of total Tl, it seems that the deeper soil of the studies profiles has not been contaminated. Due to the similar geochemical behaviors between T1 and Pb, it is effective to use the lead isotope tracing method to trace the process of Tl in the soil around the pyrite mine. |
