This work compares and evaluates the copper removal efficiency when applying electric fields to two mine tailings originating from the same mine but of different age. Eight experiments were carried out - four on tailings deposited more than 20 years ago (old tailings) and four on tailings deposited less than 2 years ago (new tailings). Parameters a...
The dissertation is concerned with the effects of oil spills on the environment, using the 2010 Gulf of Mexico event, which motivated the selection of this research topic, as a case study. It examines the spill from both a social and biological assessment in which policy, technology, and economics direct oil spill response and remediation. The diss...

PurposeThe influence of bone sorbent addition onto distribution of 90Sr in artificially contaminated soil was preliminary studied to assess the possibility of biogenic apatite utilization for reduction of 90Sr mobility and availability. Simultaneously, the disruption of soil micro- (Cd, Zn, Co, Cu, Cr, and Ni,) and macroelements (Al, Fe, Mn, K, Mg,...

To assess strategies for mitigating Pb and As transfer into leafy vegetables from contaminated garden soils, we conducted greenhouse experiments using two field-contaminated soils amended with materials expected to reduce metal phytoavailability. Lettuce and mustard greens grown on these soils were analyzed by ICP-MS, showing that some Pb and As tr...

This report shows that soil heavy metals can be totally immobilized by grinding with nano-Fe/Ca/CaO. Remediation of soils contaminated by heavy metals is a critical issue in Japan. Indeed, contaminated soils are notoriously difficult to remediate using available technologies. Major setbacks in typical immobilization techniques for heavy metals are ...

PurposeThis paper addresses the application of bioproducts produced by plants (locust bean, guar, and mesquite seed gums) to enhance remediation processes of different nature: soil washing and biodegradation methodologies.Materials and methodsThese natural gums were tested at laboratory scale to remove total petroleum hydrocarbons-diesel fraction (...

Industrial waste landfills produce great impacts on soil and groundwater. There are many industrial waste landfills in Vale dos Sinos, Southern Brazil, which were inadequately planned and maintained since the industry started in the first half of the twentieth century. The largest industrial landfill in the Valley, which causes the most severe impa...
