People Who Live Downwind Of Alberta's Oil And Tar Sands Operations Are Getting Blood Cancer
Tar sands mining is linked to leukemia.
A new study has found that levels of air pollution downwind of the largest tar sands, oil and gas producing region in Canada rival levels found in the world’s most polluted cities. And that pollution isn’t just dirtying the air — it also could be tied increased incidence of blood cancers in men that live in the area.
The study, published last week by researchers from University of California Irvine and the University of Michigan, found levels of carcinogenic air pollutants 1,3-butadiene and benzene spiked in the Fort Saskatchewan area, which is downwind of the oil and tar sands-rich “Industrial Heartland” of Alberta. Airborne levels of 1,3-butadiene were 322 times greater downwind of the Industrial Heartland — which houses more than 40 major chemical, petrochemical and oil and gas facilities — than upwind, while downwind levels of benzene were 51 times greater. Levels of some volatile organic compounds — which, depending on the compound, have been linked to liver, kidney and central nervous system damage as well as cancer — were 6,000 times higher than normal. The area saw concentrations of some chemicals that were higher than levels in Mexico City during the 1990s, when it was the most polluted city on the planet.
“These levels, found over a broad area, are clearly associated with industrial emissions,” said Stuart Batterman,” one of the study’s co-authors. “They also are evidence of major regulatory gaps in monitoring and controlling such emissions and in public health surveillance.”
