Aquatic environments represent the final outlet for a large number of contaminants produced by anthropogenic activities. Yet today, the importance of services provided to society by aquatic environments means that they need to be preserved or restored, and therefore it must be possible to assess and monitor their quality.
The challenge for the project is the development, on the basis of representative species in our hydrosystems, of tools which are sensitive to and detect possible deterioration to the quality of bodies of water. The objective of the project is to acquire knowledge for the purposes of diagnosing and assessing the eco-toxicological risk and monitoring aquatic environments. The project focuses on the effects in realistic conditions (mixtures and low concentrations) on the reproductive function and its regulation, which appears particularly relevant for identifying predictive solutions to toxic effects to conserve the individual or even of its population via its descendants.
With the help of in vitro, in vivo and in situ experiments, the work will focus on three areas:
- improvement of knowledge of the physiology of the reproduction of model species in the unit and their modulation under pressure from environmental changes;
- identification and characterisation of the potential of certain solutions as biomarkers;
- definition of the conditions for analysing these biomarkers with the goal of using them in the diagnosis and monitoring of environments.
