A new study from the University of Toronto suggests that the emissions levels used to review environmental impacts of oilsands projects have likely been too low. The study, as reported in this CTV News story, did not include all sources for hazardous pollutants - specifically polycyclic aromatic hydrocarbons - in air, soil and water. While the study's authors do not suggest that health risks are too high (they are suggested to be similar to those found in a large city), they do suggest that the estimates used in reviewing new projects should be more accurate.
