"The closer you are to the source of the fresh exhaust, the worse it is," said Patrick Ryan, an environmental epidemiologist at the University of Cincinnati. Near the tailpipe, exhaust particles are small enough to lodge deep in the lungs, triggering heart attacks and hospitalizations from lung diseases such as asthma. Tiny particles can also cross the blood-brain barrier, potentially harming the nervous system. Farther away from the tailpipe, these particles clump together, growing too large to lodge deeply, said Ryan.The solution: Avoid the main roads and find a route with less traffic. You'll probably also enjoy the scenery better. You can read more at Environmental Health News. Thanks to Gloria Joannou for spotting this article!
