Cornell http://gas2.org/2008/03/27/how-diesel-exhaust-affects-your-brain/ exhaust, smoke, diesel, pollution, emissions, nanoparticlesAs if it wasn’t bad enough that particulate matter from diesel exhaust causes a range of respiratory problems including 15,000 premature deaths each year, new research shows that even short-term exposure to nanoparticles found in diesel fumes can affect brain function.

Nanoparticles can travel to the brain via the olfactory nerve, where they could cause an oxidative stress response in the region of the brain critical to information processing.

Researchers placed subjects in a room with either clean air or diesel fumes (similar to a busy street), and used a electro- encephalograph (EEG) to measure brain response. Subjects breathing the sooty air showed a stress response in the brain’s cortex within 30 minutes, which continued even after they left the room.
