Research led by Meaghan C. Bartley of the Centre for Earth Observation Science (CEOS) at the University of Manitoba, and published in Environmental Science and Ecotechnology, found evidence of impacts from both local source and long-range transport in the marine sediment of Frobisher Bay, Nunavut, via seven dated sediment cores collected from sites near Koojesse Inlet (close to Iqaluit), and inner and outer Frobisher Bay.

Contaminants detected included total mercury (THg), major and trace elements, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and per and polyfluoralkyl substances (PFASs). These findings show that pollution effects leave a long legacy in the environment and include both local and long-range effects.

John Iacozza, an environment and geography instructor at the University of Manitoba who studies polar bears’ habitat, said the later sea ice forms, the later it is before polar bears can go out onto it to hunt for food — which can force them shore and into contact with people.

As sea ice formation continues to vary, the bears could experience “dramatic impacts,” he said.
