Toxic air pollution particles found in human brains
Detection of ‘abundant’ magnetite particles raises concerns because of suggested links to Alzheimer’s disease Toxic nanoparticles from air pollution have been discovered in human brains in “abundant” quantities, a newly published study reveals. The detection of the particles, in brain tissue from 37 people, raises concerns because recent research has suggested links between these magnetite particles and Alzheimer’s disease, while air pollution has been shown to significantly
