Traffic pollution can impair human brain function in just a couple of hours, a new study suggests.

It is the first time that an experiment has found evidence of altered brain network connectivity in humans due to air pollution.

“For many decades, scientists thought the brain may be protected from the harmful effects of air pollution,” said senior study author Dr Chris Carlsten, head of respiratory medicine at the University of British Columbia (UBC) in Canada.

“This study, which is the first of its kind in the world, provides fresh evidence supporting a connection between air pollution and cognition.”
