Topic description

Context
The presence of atmospheric contaminants results either from direct emission from point sources:
incineration, use of fossil fuels, industrial activities, etc., or from diffuse emissions or re-emissions from contaminated soils or waterbodies. This phenomenon concerns a great diversity of molecules, which originate in human uses or activities releasing volatile organic compound, containing a variety of different heteroatoms constituting a large category of emerging contaminants (pesticides, plastics, tire wear additives, PFAS, etc.). For many of them, the atmospheric pathway is their main mode of dispersion.
The primary route for the removal of contaminants from the atmosphere is by dry or wet deposition
techniques. The chemical reaction initiated by atmospheric oxidants (OH, O3) are responsible for their transformation in the atmosphere. The products formed from these reactions may be hazardous and may lead to several negative implications. Deposited atmospheric fluxes of contaminants and corresponding degradation products also constitute an ecological risk for marine or terrestrial hydrosystems, apart from the potential human health risk induced by their presence in ambient air.
Goal of the project
The main goal of this thesis is to investigate their atmospheric degradation processes using different theoretical approaches unravelling their most favourable pathways and their atmospheric fate and impact to the environment. As an add-on, the evaluation of the ecotoxicity for organic contaminants will be carried out in the aqueous environment.
This project will also perform within the framework of a larger research program (CPER Ecrin; Labex CaPPA, and CDP AREA). This work will be conducted in close collaboration with two experimental groups located in Canada (Toronto Metropolitan University and Concordia University in Montréal).
