Développement d'une approche intégrée pour le diagnostic de la qualité des eaux de la Meuse

METO is involved in the work package 5: Effect at the population level - mesocosm experiment and in silico approaches.

To enhance ecological risk assessment is crucial to extrapolate from toxicity data measured at the organism level to biological levels relevant to support risk management. Indeed, while the experimental approaches can provide relevant information regarding the capacity of chemicals to disrupt key physiological processes at organism level, they are limited to address impact at population level. In this context, population models can play an important role in bridging the gap between what is measured (organism-level endpoints) and what needs to be protected (population-level endpoints.

WP 5 combines modelling approaches and mesocosm experiment to develop and test the predictive capacities of models developed for three different species: Gammarus, zebra mussel and stickleback. The model will be used to predict the impacts of a chemicals mixture characteristic of the effluents of sewer systems located in the Northeast France.
