A new study reveals that prenatal exposure to common air pollutants like NO₂, PM2.5, and black carbon is associated with subtle but measurable changes in fetal brain structure during the second and third trimesters. Using specialized ultrasound scans, researchers found increased volumes in brain cavities, including the lateral ventricles and cisterna magna, and changes in areas related to motor coordination and sensory processing.
