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 focus on selected soil and groundwater pollutants and the appropriate remediation technologies. The case studies draws on the general insight in chemical, biological and physical processes presented in the the course. Each case is solved by groups of students and it is presented as a short report and an oral presentation.
 
Målbeskrivelse
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 fate and 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.

After completion the course the student should be able to:
Knowledge:
- Describe key properties and processes of soil, and environmental pollutants critical for sorption, degradation, bioavailability and transport of pollutants in terrestrial systems
- Show overview of and classify the main inorganic and organic pollutants in terrestrial ecosystems
- Classify and summarize the molecular mechanisms controlling pollutant degradation/transformation and bonding in soils and water
- Knowledge of analytical procedures and monitoring strategies for pollutants in geoenvironments
- Show overview of the relationships between land use and soil/groundwater quality
- Identify and reflect about the main strategies for soil and groundwater remediation

Skills:
- Apply and demonstrate the use of general principles from chemistry, physics and microbiology in environmental chemistry
- Compute chemical and physical properties of pollutants and pollutant fate in terrestrial ecosystems
- Quantify pollutant sorption, degradation and transport using different types of models and calculus
- Apply and evaluate procedures for soil and water cleaning (remediation)
- Retrieve and critical examine environmental chemical data

Competences:
- Combine data and information from different sources in calculus, prediction and evaluation of pollutant mass balances, distribution, fate and effects in terrestrial ecosystems
- Diagnose the processes critical for the fate of any pollutant, and critical selection of tools for analysis and evaluation
- Propose, analyse and assess the use of different remediation technologies and strategies for clean-up of simple and complex pollutant scenarios
- Discuss the complexity of how modern agrotechnology and land use affect soil and groundwater quality
- Discuss the criteria and considerations relating to key terms such as "toxic", "pollution", "threshold concentrations" and "soil and groundwater quality"
