A quantitative analysis method for ecological-health risks caused by rainfall-induced soil erosion at the Laronde Mine Eng. Geol. (IF 7.4) Pub Date : 2024-01-19 Yuxuan Xue, Fereshteh Sattari, Lianne Lefsrud
Understanding the migration and dispersion of potentially toxic elements (PTEs) from soil erosion is integral to managing mine site risks. Modeling PTEs distribution in this mass movement is a significant challenge. This research quantitatively analyzed the ecological-health risks associated with rainfall-induced soil erosion (debris flow) at the LaRonde Mine's tailing pile (Quebec, Canada). The present
