The TRAJECTOIRE project was launched in January 2020 and will run for 4 years. Its aim is to establish the trajectories of man-made contaminants at the outlets of the major French river basins (Rhône, Loire, Seine, Garonne, Rhin, Meuse and Moselle). The aim is to study their pathway, from their introduction into the environment to their presence in environmental compartments, over the course of the 20th century. This period was punctuated by technological and industrial development, followed by a gradual recognition of the impact of this development on the environment.
Three major families of contaminants introduced into the environment by human activities will be studied as part of the TRAJECTOIRE project:
Radionuclides,
Microplastics and by-products such as phthalates,
And critical metals: ultra-rare metals used in cutting-edge technologies, such as gadolinium, indium, terbium, europium, palladium, platinum and germanium.
The ultimate aim of the TRAJECTOIRE project is to develop a predictive model of contaminant concentrations in river systems by considering the evolution of anthropogenic pressures on the basis of scenarios. The research work will make it possible to assess the trajectories of the contaminants studied, i.e. the response of environments subjected to anthropogenic disturbances applied to their catchment areas, as well as the capacity of large rivers to return to their initial state after a disturbance, i.e. their resilience capacity.
The TRAJECTOIRE project aims to provide stakeholders with a decision-making tool on environmental measures (regulations), management methods for dismantling and remediation operations and the materials to be used in new technologies, with a view to protecting hydrosystems.
The TRAJECTOIRE project, led by IRSN, brings together 7 French partners. The ANR is funding this project as part of its 2018 generic call for projects on the "Human-Environment Interactions" theme.

The Trajectoire project is led by IRSN and funded by ANR (ANR-19-CE3-0009, 2020-2024).
On 2 and 3 November, the MIO welcomed around twenty researchers involved in the TRAJECTOIRE project for the 4th meeting of the consortium.
