SFKKA9101U Aquatic Environmental Chemistry
MSc Programme in Agriculture - core course
MSc Programme in Environmental Chemistry and Health - compulsory
The course covers the following topics:
Aquatic environmental issues:
- The geochemical processes underlying the formation of lakes, seas and running water and chemical composition of these waters.
- The carbonate chemistry and how it governs pH in natural waters.
- Overview of typical pollutants in water and sediment matrices.
- Metal solubility, complexation and speciation of in aquatic environments.
- Partitioning of pollutants from water to living media (bioconcentration and biomagnification).
- Redox chemistry in aqueous systems.
- Abiotic and biotic transformation processes of organic chemicals in aquatic systems such as hydrolysis, photolysis and biotransformation including kinetics, transformation pathways and formation of transformation products
- Mass balance modelling of pollutants in aquatic systems such as lakes.
Health science aspects:
Human health and water pollution
- Consumption via contaminated food
- Water borne diseases caused by microbes
Human health and drinking water quality
- Pesticides, pharmaceuticals and other xenobiotic residues in drinking water in industrialised and developing countries and health consequences hereof
- Arsenic in drinking waters
This course is running in parallel to the course in Terrestrial
Environmental Chemistry (LIFE-KU) in module C. Therefore, the
lecture on general water and soil pollution is given as a common
lecture between the two courses. Lectures on biodegradation
kinetics/pathways, metal speciation and redox processes are given
in both courses but focussing on water (PHARMA) and soil (LIFE)
Teaching and Learning Methods
The course will in 2013/14 be based on lectures, kollokvier and a theoretical student project. Lectures and kollokvier are based on a textbook, lecture notes and scientific papers. The project work focuses on selected pollutants and draws on the general principles in chemical and biological processes (such as hydrolysis, photolysis and bio-transformation) that are fundamentally important in aquatic environmental chemistry.
