Developing and conducting projects for improving environmental risk assessment of organic chemicals is the center of the ecotox group’s research activities .
For example, we investigated the limits of the mixture models application for risk evaluation. We also validated mixture risk predictions with field observations.. We also developed new testing procedures for non-classical organims such as amibia or for non-classical exposure such as sequential pulse exposure.
Nowadays, there is a need in ecotoxicology to better understand the bioavailability of the hydrophobic organic chemicals as well as their toxicity, and to better describe their bioamplification along the trophic chain. In a current PhD project, we investigate the fate and behaviour, the bioaccumulation/bioamplification, and thus the risk, of persistent organic compounds like PBDE (flame retardants). In particular, we aim in estimating the trophic magnification factors for these compounds.
Furthermore, we also conducted applied projects in collaboration with local authorities. For example we developed an approach to include mixture in water quality assessment or we proposed substance flow analysis for urban water management.
Regarding teaching, our group is involved in courses at the bachelor and master level, as well as in continuous education.
Finally, one important part of our work is dedicated to science outreach.
