2. Analysis of PAHs and their transformations products in contaminated soil and remedial processes
Abstract : Soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) is often found at the sites of former gasworks and wood-impregnation plants. Since PAHs are toxic these sites represent a hazard to human health and the environment, and therefore they need to be treated, preferably by a method that destroys the contaminants, and thus eliminates the problem permanently.

3. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments
Abstract : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. READ MORE

4. Remediation of mercury polluted soil
Abstract : Mercury in contaminated soil constitutes a wide spectrum of species with highly different properties due to the chemical complexity of the element. Assessments of risk, ecological effects and removal potential require process and mobility studies. READ MORE

5. Soil-Steel Composite Bridges : Research advances and application
Abstract : Soil-steel composite bridges are considered competitive structures being an economical alternative to similar span concrete bridges. This frequently stimulates practitioners to push their design limits and expand the different areas of application including their performance in sloping terrain. READ MORE
