11. Geochemical Characterization of Historical W, Cu and F Skarn Tailings at Yxsjöberg, Sweden : With focus on scheelite weathering and tungsten (W) mobility
Sammanfattning : Little attention has been paid to tailings from skarn ore deposits and their environmental impact, even though they can contain elevated content of elements of potential concern. Historical skarn tailings from a former scheelite mine at Yxsjöberg, Sweden, containing e.g. LÄS MER
12. Resistivity investigation and monitoring for detection of internal erosion and anomalous seepage in embankment dams
Sammanfattning : Methods for monitoring seepage and detecting internal erosion are essential for the safety evaluation of embankment dams. Internal erosion is one of the major reasons for embankment dam failures, and there are several tenths of thousands of large embankment dams in the world. LÄS MER
13. Post-Mining Restoration in Zambia : Screening native tree species for phytoremediation potential
Sammanfattning : Africa has a long history of mining, which has generated a large amount of wastes (tailings dams and overburden materials) that are hazardous for the environment and human health. Phytoremediation, which involves the use of plants and microorganisms to reduce the toxic effects of heavy metals in the soil environment, is considered an efficient, eco-friendly and cost-effective restoration method.

14. Excess pore water pressure generation in crushed and fine granular materials under cyclic traffic loads
Sammanfattning : Excess pore water pressure can develop in subgrades of railway and pavement substructures due to cyclic loading from heavy traffic, leading to the migration of fine particles into upper layers. This migration can clog pores and diminish the drainage capacity of upper layers,negatively impacting the long-term performance of sub-structures and service life, ultimately risking failure. LÄS MER
