Stuck In Traffic? Smells Like Stress

LONDON - Inhaling diesel exhaust triggers a stress response in the brain that may have damaging long-term effects on brain function, Dutch researchers said on Tuesday.

Previous studies have found very small particles of soot, or nanoparticles, are able to travel from the nose and lodge in the brain. But this is the first time researchers have demonstrated a change in brain activity.

“We can only speculate what these effects may mean for the chronic exposure to air pollution encountered in busy cities where the levels of such soot particles can be very high,” said lead researcher Paul Borm from Zuyd University.
