Traffic pollution has long been linked to memory problems but a new study in Canada has revealed that breathing in diesel exhaust fumes for just a couple of hours impairs brain function and cognition.

Air pollution erodes neurological health and also increases a person's risk of death from all causes.

Experts at the University of British Columbia and the University of Victoria exposed 25 individuals aged between 19 and 49 to filtered air and contaminated with diesel exhaust.

The results showed that breathing in diesel exhaust fumes decreases functional connectivity - a measure of how regions of the brain interact and communicate with each other.

Dr. Chris Carlsten, a senior author of the study, said: "People may want to think twice the next time they're stuck in traffic with the windows rolled down.

"It's important to ensure that your car's air filter is in good working order, and if you're walking or biking down a busy street, consider diverting to a less busy route."
