Summary:

Topic: Study undertaken in response to concerns that the ecosystem around Fort Chipewyan, the lower Athabasca River, Lake Athabasca and the Peace-Athabasca Delta had been contaminated with toxic polycyclic aromatic compounds (PACs) due to oilsands development.

Findings: The Athabasca Delta is a “natural repository of PACs” and has been for at least two hundred years. The researchers found “no measurable increase” in contaminants “since onset of oil sands development,” and “no evidence that industrial activity has contributed measurably to sedimentary concentration of PACs supplied by atmospheric transport.”
