As Canadian oil exports increase, research explores effects of crude oil on native salmon

"Crude oils are a complex mixture of chemicals and represent a pervasive environmental stressor. Canada sits on the world's third largest crude oil reserve, found as bitumen in the Athabasca oil sands. Ninety-eight percent of Canada's oil comes from the oil sands, and 99 percent of our exports go to the U.S.," said study author Sarah Alderman, PhD. "As plans to bolster the export capacity of this resource intensify, so too do concerns for the added risk of spills and environmental contamination." New pipeline projects, including the Trans Mountain Expansion Project, have the potential to increase diluted bitumen shipped through salmon habitat to seaports on the West Coast.

In the lab, Alderman's research explores the effects of crude oil exposure on anadromous salmon in collaboration with scientists at the Universities of Simon Fraser and British Columbia. "These fish spend parts of their life in both freshwater and the ocean, and our research is critical for finding out whether exposure leads to changes in the physiology or performance of the...
