New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Emission density estimates for the three PAHs that account for tailings pond disposal are much closer to estimated global averages than estimates based on the available emissions datasets, which fall close to the global minima. Tailing ponds are not the end of the journey for the pollutants they contain. —Abha Parajulee.
