High levels of air pollution, particularly from particulate matter (PM2.5)
Exposure to poor air quality during pregnancy can restrict fetal growth, often resulting in low birth weight.
Prolonged exposure to high AQI can impair lung development in the fetus.
Pregnant women exposed to high pollution levels have an increased risk of developing preeclampsia.
Pollutants such as PM2.5 and nitrogen dioxide (NO2) can affect brain development.
