The local toxic air pollution released by tar sands oil extraction has
been
underestimated by a large factor
because of a flaw in the system used to measure it.
The article misuses the concept of percent; as a result, I can’t tell
for sure what the factor might be. As best I can tell, the
factor of underestimation ranges from 18 to 62, but I can’t be sure.
