Even brief exposure to air pollution may impair brain function: Study

Toronto: Just two hours of exposure to air pollution may impair human brain function, according to a study.

The researchers found that exposure to diesel exhaust for just two hours causes a decrease in the brain's functional connectivity - a measure of how different areas of the



brain interact and communicate with each other.

The study, published in the journal Environmental Health, provides the first evidence in humans, from a controlled experiment, of altered brain network connectivity induced by air pollution.
