Exposure to Air pollution in a long term can have detrimental effect on the brain, according to a new study involving MRI scans conducted on 943 healthy adults. The research team used magnetic resonance imaging (MRI) for study subjects above 60 years of age in New England region and compared their brain structure and size. The study results were compared to pollution levels at the place of residence of the study subjects.
With 2 micrograms per cubic meter higher pollution of fine-particle, the brain volume reduced by 0.32 percent on an average, according to the research team. Car exhaust and other vehicle related pollution is the main cause of fine-particle pollution.
