Phytoremediation of contaminated urban sites (brownfields)

Labrecque phytoremédiation

The utilization of plants to decontaminate polluted soils is one of the laboratory’s research themes. In recent years, various projects have studied strategies to promote the establishment of plants on sites that may be contaminated by organic or inorganic pollutants.

Our research team is interested in the development of green approaches to decontaminate and rehabilitate polluted sites, in particular brownfields or vacant urban lots, using plants. We study low cost solutions to restore lost ecological integrity to these sites. By planting species adapted to the difficult conditions that characterize these sites, we have completed several projects that simultaneously “green” and rehabilitate a site, following decontamination.

A decontamination project on a site located at the St. Charles Industrial Park (Parc d’Entreprises Saint-Charles – PESC), formerly known as “Technoparc”, is currently in progress. The issue in this case involves diffuse pollution caused by the release of multiple contaminants into the St. Lawrence River.
