Pollution Might Cloud Minds of Older Men
New research finds a link between vehicle emissions and cognitive function in older people.
People who live in polluted cities can see the grit and dirt produced from vehicle engines but some of the most damaging emissions are only now starting to be understood. They’re ultrafine particles that are way too small to be seen. Hundreds of these particles, placed side by side, match the width of a human hair and are primarily produced by combustion in diesel engines.
Harvard doctoral researcher Melinda Power says we now understand that ultrafines are a more significant problem than emission gasses or those large particles that make your skin dirty.
