Changes in the ecological risk of heavy metals after soil remediation in a typical Brownfield: A case study of Guixi smelter in Jiangxi Province

This paper was seleced Qingyuan as a case study, in order to analyze Hg, As, Cu, Zn, Pb, Cd, Ni, Cr concentrations of the soil samples. And used the Hakanson potential ecological risk index method to assess the potential ecological risks of concentrations of heavy metals in soil. The results shows that the average concentration of Hg, As, Cu, Zn, Pb, Cd, Ni, Cr in soil is 6.45, 0.26, 20.25, 119.11, 181.67, 189.22, 0.27, 32.92, 201.35 mg•kg-1 respectively. The rank by severity of ecological risk as Hg > Cu > Pb > As > Cr > Cd > Ni > Zn, based on their single-element indexes. Heavy metals in several samples of the soil have posed a serious threat on the ecosystem.

And Migration

Understanding the spatial distribution and pollution characteristics of heavy metals in lake sediment is crucial for studying deposition and migration processes, assessing lake conditions, and determining the extent of remediation dredging. The present work is a case study of heavy metal pollution in Shitang Lake in Anhui province, China. Heavy metal concentrations were determined in sediment at locations across the lake to a depth of 100 cm, and pollution levels were assessed on the basis of the Geoaccumulation Index (Igeo) and Potential Ecological Risk Index (RI). Hg and Cd were the predominant heavy metals in the sediment, and the Igeo and RI indicated high pollution levels in the northern and southern zones of the lake. These findings can be used to guide the prioritization of dredging operations.
