| Kursets målsætning | |||||||||||||||||
| The objectives of the course are to comprehend and to study i) how soils respond to man-made disturbances, ii) the effiency of soils as "filters", i.e. the efficiency of soils to degrade and retain environmental pollutants, iii) the effects of pollutants in a global geochemical context, iv) quantification of soil processes for assessment, modelling and forecasting the fate of pollutans in soil and groundwater, and v) biotechnological methods for cleaning soils and groundwater. | |||||||||||||||||
| Kursusindhold | |||||||||||||||||
| Brief review of soils, including chemical composition and properties of soil minerals and humic matter. Interactions between abiotic and soil biochemical processes. Natural soil forming processes affecting soil pollutants such as acidification, clay migration, redox processes and leaching. Characterization of microbial degrader populations in soil and groundwater. Sampling, fractionation and analysis of soil solutes. Spatial variation of pollutant degradation and sorption in soils. Review of pollutants in soil environments with emphasis on biogeochemical properties, monitoring data and mass balances for pollutants including heavy metals, radionuclides, acids, pesticides, endocrine disruptors, detergents, PAH's, halogenated compounds, veterinary drugs/biomedicine, natural toxins, anthropogenic nanoparticles and microbial contaminants from manure and other organic waste products. Activity and mode of action of soil enzymes and soil microorganisms. Gas-water exhange. Complexation and speciation, solubility, and hydrolysis in soil solution. Sorption (pollutant binding) processes including ageing and bioavailability. Reactions at particle surfaces including engineered nanoparticles. Redox processes, zonations and sequences. Equilibrium computation software. Degradation pathways, formation of metabolites, and models to quantify degradation and mineralization kinetics. Software for computing speciation and for QSAR estimation of pollutant properties. Modelling of water and solute transport. Macropores and colloidal transport. Integration of soil chemical, physical and microbiological properties into soil quality estimates with focus of soils as filters. Cleaning and remediation of polluted soils with emphasis on bioremediation technologies such as enhanced microbial degradation of organic pollutants, bioaugmentation (use of introduced microorganisms for degradation), phytoremediation (use of plants to degrade or absorb pollutants) and use of biodetergents and bioligands for pollutant leaching. | |||||||||||||||||
| Undervisningsform | |||||||||||||||||
| Lectures, theoretical exercises and three case studies. One 1-day excursion comprising examples of soil pollution, soil remediation, land use and groundwater quality. Lectures are based on the textbook used. The topics of the theoretical exercises run in parallel with the topics treated in the lectures and aims at training typical computation methods used in environmental geochemistry. Groups of students work together to discuss and solve the selected problems. The case studies, which occupies the three last weeks of the course, focus on soil and groundwater remediation technologies and draws on the general insight in chemical, biological and physical processes presented in the first part of the course. Each case is solved by groups of students and it is presented as a short report or an oral presentation. | |||||||||||||||||
