This course is designed to provide an in-depth understanding of the potential effects, on human health, of exposure to environmental contaminants and the underlying mechanisms of toxicity, with special attention to population groups bearing a disproportionate exposure burden. In this course, students will learn about methods used to investigate the health effects of environmental contaminants, and specific classes of environmental contaminants (sources, pathways of exposure, human health effects, mechanisms of toxicity). To understand the complexity of factors influencing environmental quality and health, students will work with real air quality data collected from various Canadian regions and will assess the interplay between the sociodemographic and built environment and levels of exposure to contaminants.
