"According to the World Health Organization, over 4.2 million people die
prematurely each year due to long-term exposure to fine particulate outdoor air
pollution, also known as PM2.5. However, a recent study involving researchers
from McGill University suggests that this number may be underestimated. The
study found that mortality risk was increased even at very low levels of PM2.5,
levels that were previously not considered dangerous. These microscopic toxins
can cause a variety of cardiovascular and respiratory diseases, as well as
cancers.
“We found that outdoor PM2.5 may be responsible for as many as 1.5 million
additional deaths around the globe each year because of effects at very low
concentrations that were not previously appreciated,” said Scott Weichenthal,
an Associate Professor in the Department of Epidemiology, Biostatistics, and
Occupational Health at McGill University and the lead author on the recent
paper in
Science Advances."
