Dre Elodie Passeport - Compound Specific Isotope Analysis to track contaminant fate in green infrastructure

Compound Specific Isotope Analysis (CSIA) is a widely-used tool to identify chemical degradation in groundwater contaminated with traditional compounds, e.g., benzene and chlorinated ethenes. Our group is investigating its potential to track contaminant fate for less traditional molecules and surface water environments. In this talk, I will discuss challenges and opportunities for CSIA applications to constructed wetlands. I will show how CSIA allowed to identify the reaction mechanisms governing the phototransformation of benzotriazole, a corrosion inhibitor present in urban stormwater runoff. I will then present our CSIA work on the fate of 2,3-dichloroaniline in constructed wetlands at a contaminated industrial site. Altogether, I hope to demonstrate that CSIA is an exciting tool that can be use more widely than it is today.

Biography

Elodie Passeport is an Associate Professor at the University of Toronto, and Tier II Canada Research Chair in Environmental Engineering and Stable Isotopes. Dr Passeport is cross-appointed in the departments of Civil and Mineral Engineering, and Chemical Engineering and Applied Chemistry. She obtained her PhD in Water Sciences in 2010 from AgroParisTech in France, and then conducted a postdoc in the Plant and Microbial Biology department at UC-Berkeley and one in the Earth Sciences department at the University of Toronto. Her research group studies the fate and removal of contaminants from water, in natural and engineered environments. Elodie Passeport received the Ontario Early Researcher Award in 2020, the Bill Burgess Teacher of the Year Award for Large Classes in 2018 from the Department of Chemical Engineering and Applied Chemistry and the Early Career Teaching Award in 2020 from the University of Toronto Faculty of Applied Science and Engineering.
