Pollution and Bioremediation of Ecosystems

This course aims to provide a better understanding of the main types of pollutants (organic vs. inorganic), their source(s), their fate in the environment, and how they interact with living organisms (bioaccumulation, biotransformation, effects). Methods used in decontamination and bioremediation will be discussed. Particular emphasis will be placed on the contribution of terrestrial and aquatic plants to phytoremediation, as well as on the role of microorganisms (bacteria, fungi) in the mechanisms of biodegradation, biotransformation, and biosequestration. This course unit will be illustrated through various case studies that address examples of chronic and acute/accidental pollution of water, air, and soil. In particular, the course will cover the treatment of pollution associated with the mining, oil, plastics, and agrochemical industries, as well as the treatment of liquid effluents (wastewater, industrial effluents). A field trip to Saint-Laurent-Le-Minier will provide an opportunity to observe a current phytoremediation project at a former mining site.

1) gain theoretical knowledge of the main types of pollutants (organic vs. inorganic), their source(s), their fate in the environment, and how they interact with living organisms, as well as existing approaches to pollution control and bioremediation;

2) be able to apply concepts and tools at the intersection of various disciplines (ecology, organismal biology, ecophysiology, microbiology, biochemistry, ecotoxicology) to address environmental issues and challenges related to the management and protection of species and ecosystems;

3) Understand and critically analyze scientific literature.
