Thème de recherche : Suivi de la présence des hydrocarbures aromatiques polycycliques (HAPs) dissous en eau de mer à l’aide des matrices d’excitation-émission de fluorescence.

The main goal of this study is to develop a fast and efficient approach to characterize the presence of hydrocarbons (PAHs) in natural waters based on fluorescence. The aromatic moieties contained in the PAHs can emit strong fluorescent signals. We used this property to measure the cumulative fluorescence signal with fluorescence excitation-emission matrices (EEMs). Then, we used the statistical treatment Parallel Factor Analysis (PARAFAC) to retrieve the individual contribution from each individual PAH of the sample. The EEMs-PARAFAC project, make it possible to identify PAHs in a more direct, fast and less expensive way. This allows to quickly identifying the PAHs composition, measure their presence, their concentration, and evolution in time when there is an oil spill.

Work experience / Expérience professionnelle

Oil spill simulation in mesocosms joint project Mexico-Quebec-Argentina. Multidisciplinary work cofounded by FONCICYT (Mexican National Council of Sciences and Technology) and by the XVe Working Group Québec-Mexico 2015-2017, with collaborators from ECOSUR, CINVESTAV, ISMER, UQAR, IML, UNPSJB, CONICET. The main goal of this research was to study the effects of an acute oil spill in key stages of ecological phytoplankton succession (pre-bloom, bloom and post-bloom), to determine their sensitivity in terms of community responses. Chemical Oceanographer and sampling, 2016 (June, July).
