New Pipeline Study

The US State Department released on Friday a report on the environmental impact of Keystone XL, raising few objections to the prospective ecological damage and harm to human health caused by the pipeline and its functions.

A new study by the University of Toronto-Scarborough published Monday in the Proceedings of the National Academy of Sciences reported that Canadian officials may have underestimated emissions of harmful carcinogens known as polycyclic aromatic hydrocarbons (PAHs) from Alberta tar sands.

Specifically, the report cited the emission levels of PAHs as being one hundred to one thousand times greater than previously believed.

That’s a pretty big gap in estimations.

[Removing tar sands oil] uses an excessive amount of water, releases toxic metals into the local environment, and unleashes an estimated 14 to 17 percent more greenhouse gas emissions than regular crude.

PAHs include phenanthrene, pyrene and benzo(a)pyrene, which “are among the most toxic hydrocarbons,” said Jules M. Blais, a University of Ottawa chemical and toxicology professor, according to Climate Central. “They’re some of the worst things out there.”

PAHs should be of concern to anyone living along the Keystone XL route, and those in the nearby vicinity of the Alberta tar sands region are especially at risk.

“From the standpoint of Keystone, the concerns are regarding potential breaches that could contaminate soils,” Blais said.
