Title: Persistent contaminants in marine mammals: trends and patterns in a changing world

Series: Managing Coasts in a Changing World seminar series

Speaker: Dr. Chris Metcalfe

Free public lecture, all welcome!

Marine mammals accumulate high concentrations of persistent organic pollutants (POPs) because of their high fat content and because many species of cetaceans and pinnipeds occupy the very top of the marine food chain. In some areas of the world, such as in northern Canada, POPs that accumulate in marine mammals can impact human health as a result of the consumption of “country foods” by Indigenous peoples. Monitoring of marine mammals provides a window into global trends in POPs concentrations that are occurring as a result of changes in climate, the use patterns of industrial and agri-chemicals, and reduced biodiversity in the oceans. In this presentation, Dr. Metcalfe will review his research experience with contaminants in marine mammals from various locations around the world, as well as data that have been generated by other researchers working in this field. This presentation will be of interest to those who want to know more about toxic chemicals in the environment, as well as contaminant trends and the potential impacts of POPs in marine mammals.
