Researchers from the University of Michigan (USA) found that air contaminated with PM 2.5 particles is associated with an increased risk of dementia. The results of the research have been published magazine JAMA Internal Medicine (part of the JAMA group).
PM2.5 is the smallest particles, 10–2.5 microns in size (thinner than a human hair), containing both solid microparticles (soot, asphalt, mineral salts, heavy metals) and the smallest liquid droplets. These particles settle in the lungs and cause inflammation and may possibly cross the blood-brain barrier and reach the brain.
Scientists have found that the most nephrotoxic are particles from agricultural emissions and wildfires. The authors came to these conclusions after analyzing data from nearly 30,000 people from 1998 to 2016, all living in different regions and undergoing medical examinations. As it turned out, staying longer in a highly polluted area meant an increased risk of developing dementia.
