Air Pollution Collected Near Freeways Linked to Brain Damage in Mice in Experiment

 

Scientists who exposed laboratory mice to the type of air pollution found near freeways -- already proven to cause respiratory disease, cancer, heart attacks and premature death -- have now linked such pollutants to brain damage.

Mice exposed for 150 hours spread over 10 weeks showed damage similar to that caused by Alzheimer┬┤s Disease and signs of memory loss. Study senior author Caleb Finch said inhaled particulates appear to affect brain neurons.

The study was inspired by research from Mexico that showed that the brains of accident victims in smoggy Mexico City showed significantly more inflammation and other signs of Alzheimer┬┤s than did those of victims from Veracruz, which has cleaner air.

  surely, this is old news  
 
The Lead(Pb) content in the exhaust has always played havoc with brain development, memory and brain development.

It was in documentaries since the 70s.

I would like to see this study concentrated on drivers who have to drive through long tunnels during rush hour to and from work and see what health problems they have. The exhaust fumes should be the most concentrated in tunnels. IMO

Lead was banned from gas decades ago. These particulates are from incompletely burned fuel (NOx gas, various hydrocarbon chains, and, possibly, rubber particles from tires).

And also superfine particles of pulverized freeway surface materials.
