Long-term air pollution exposure is associated with neuroinflammation, an altered innate immune response, disruption of the blood-brain barrier, ultrafine particulate deposition, and accumulation of amyloid beta-42 and alpha-synuclein in children and young adults

Air pollution is most often seen as a contributor to children’s asthma and other respiratory problems. Emerging research, however, suggests that air pollution is linked to neurodevelopment concerns as well. Studies recently published in Pediatrics and Environmental Health Perspectives, in fact, found lower IQ levels in the children of mothers who were exposed during pregnancy to an array of pollutants, including polycyclic aromatic hydrocarbons (PAHs) and organophosphate pesticides. Given school is back in session, how a child performs on IQ tests and other exams is a heightened concern for parents and school administrators. This research suggests that some kids may have a more challenging time reaching their full potential because of these early life exposures to air pollutantants. On this call, leading researchers discussed their recent findings as well as the potential implications for children’s neurodevelopment.
