MSc student for project on treatment of cyanotoxins at Aarhus Universitet


More and longer events of cyanobacterial blooms are resulting in the irrigation of crops with contaminated water. Thus, the consumption of contaminated vegetables increases the risk of poisoning to humans. The usage of constructed wetlands to mitigate cyanotoxins contamination from surface waters is deemed interesting due to their proven capacity to reduce pollutants, their low- technological requirements and landscape integration. However, it is currently unknown if constructed wetlands can be used to remove the cyanobacteria biomass and degrade the cyanotoxins. In addition, a balance is needed in terms of process optimisation. Ideally, we want to clean the water from the cyanobacteria/cyanotoxins, while the nutrients should remain available for the crops. We are performing in-depth characterization of the potential for removal, including removal mechanisms and cyanotoxins biotransformation, as well as how shock loads of cyanobacteria may impact the microbial community in the constructed wetlands.

The MSc project will support the activities of the project WETCYANO financed by the Independent Research Fund Denmark and TOXICROP financed by the European Union.

The work will be based at the Department of Environmental Science of Aarhus University. Please note that the Department of Environmental Science is located at Risø Campus in Roskilde.
