Student Research Projects

The Ecotox Centre offers students the possibility of serving internships or working on bachelor or master projects on practice-relevant topics from applied ecotoxicology for a duration of 3 to 6 months. Four jobs are available in Dübendorf and Lausanne for these projects. Currently possible topics are listed below. If you are interested, please send the following information and documents to Brigitte Bracken.

Biomonitoring of treated wastewater
We are currently testing various online biomonitoring systems to evaluate their suitability for monitoring wastewater quality. In this context we would like to test a new system: the "Toxmate" from the French company Viewpoint. The system works by recording and evaluating the swimming patterns of test organisms such as amphipods over a longer time period using a camera. The wastewater is continuously passed through test chambers containing the test organisms.
Experiments with the Toxmate will be conducted and evaluated at the experimental wastewater treatment plant at Eawag/Dübendorf. Within your position you are going to carry out and evaluate a series of experiments investigating the reaction of the organisms after the introduction of spike substances into the system. Both field work (catching the organisms) and laboratory work (preparation of the substances), evaluation on the PC (using R etc.) and close cooperation with Viewpoint are on the schedule.
Start: February/March 2022 for 5-6 month.

Bachelor Project: Technical aspects of water analysis
At the Ecotox Centre several bioanalytical methods for the monitoring of water quality are applied. In these bioassays, either native water samples (without sample preparation) or concentrated water samples are tested for their toxicity. To improve the analysis, the following questions should be examined:
What is the best extraction method? Can we accumulate all toxic substances in a water sample with the same mechanism of action?
How long can chemical substances be detected in water samples?
