Article Synopsis
- In China, places with lead and zinc pollution are affected by natural events like freeze-thaw cycles and acid rain, but scientists aren’t sure how these affect toxic elements in the soil.
- A study showed that the frequency of freeze-thaw cycles was really important for the release of these toxic elements, but lowering the acidity of the soil didn’t always lead to more pollution.
- The results help us understand how minerals in the soil break down and how toxic elements move around, which can help improve cleanup methods for contaminated areas.
The longevity evaluation of multi-metal stabilization by MgO in Pb/Zn smelter-contaminated soils.

April 2024
The re-mobilization risks of potentially toxic elements (PTEs) during stabilization deserve to be considered. In this study, artificial simulation evaluation methods based on the environmental stress of freeze-thaw (F-T), acidification and variable pH were conducted to assess the long-term effectiveness of PTEs stabilized by MgO in Pb/Zn smelter contaminated soils. Among common stabilizing materials, MgO was considered as the best remediation material, since PTEs bioavailability reduced by 55.

One of most applicable technique to clean up Cr pollution is chemical reduction. However, the Cr(VI) concentration in soil increases again after remediation, and meanwhile the yellow soil would appear, which is commonly called as "yellowing" phenomenon.
