Toxic air pollution particles found in human brains, possible Alzheimer’s link – study

‘Tiny magnetic particles called “magnetite nanoparticles” present in air pollution have, for the first time, been discovered in human brains, and researchers think it could be a possible cause of Alzheimer’s disease.
Scientists examined brain tissue from 37 people aged between three and 92 in Mexico and in Manchester, UK.
They found that many of the highly magnetic brain samples were from people under 40 from Mexico City who had been exposed to high levels of air pollution, and from people in Manchester over 65 years at time of death with moderate to severe Alzheimer’s disease.’
