Research involves

Understanding the movement and transformation of contaminants in a changing world.

Research relevance

This research will help develop knowledge and tools to manage risks associated with ecosystem contamination.

Protecting ecosystems in a changing world

We live in a world in which the environment has been profoundly modified by humanity: we have altered the landscape, our activities are contributing to climate change, and, through our industrial, agricultural and municipal acitivies, weare releasing into the environment a number of potentially toxic substances. Our impact on the planet is so great, in fact, that some propose calling the current geological epoch the “Anthropocene.” In this context, we are—and will remain confronted with—many environmental challenges as a society.

As Canada Research Chair in Global Change Ecotoxicology, Université de Montréal’s Dr. Marc Amyot is addressing these challenges by studying the complex interactions between global change and the behaviour of contaminants.

Dr. Amyot and his team will explore, for example,  how the mobility of contaminants will be affected by the thawing of Northern permafrost; with expanding mining and industrial development, it is urgent to establish a better grasp of how thawing permafrost will release contaminants that may damage fragile ecosystems.

Amyot will also study the projected movement of contaminants up the food chain, with an emphasis on the impact to human communities relying on fishing and hunting.

Finally, Amyot will develop biological remediation technologies for soil decontamination, adapted to northern conditions. These technologies will be based on an integrated ecological approach and will use local products, in a circular economy perspective.

This type of research will enable environmental managers to make science-based decisions to decrease the risk posed by contaminants in the changing North.
