Combustion-derived nanoparticles in key brain target cells and organelles in young urbanites.

A new study by researchers at the University of Montana, Universidad del Valle de México, Instituto Nacional de Pediatría, Boise State, and Universidad Nacional Autónoma de México, heightens concerns over the detrimental short- and long-term impact of airborne iron-rich strongly magnetic combustion-derived nanoparticles (CDNPs) present in young urbanites’ brains. Using transmission electron microscopy, the researchers documented by abundant combustion nanoparticles in neurons, glial cells, choroid plexus, and neurovascular units of Mexico City children, teens and young adults chronically exposed to concentrations above the US-EPA standards for fine particulate matter. Residents in Mexico City are exposed from conception to harmful neurotoxic air pollutants. These findings are published in the Journal of Alzheimer’s Disease.

The detrimental impact of these tiny particles getting into the…
