Exposure to polycyclic aromatic hydrocarbons (PAHs) is linked to a higher risk of premature rupture of membranes during pregnancy. That's the sac around the baby breaking too early.
Air Pollution and Pregnancy Complications
A 2026 study in Ecotoxicol Environ Saf found an association between PAH exposure and premature rupture of membranes (PROM). PROM can lead to preterm birth, infection, and other serious complications for both mother and baby.
PAHs come from vehicle exhaust, cigarette smoke, grilled and charred food, industrial emissions, and burning wood or coal. They're everywhere in urban environments, and pregnant women breathe them in daily.
What You Can Do
Avoid secondhand smoke. Limit grilled and charred foods during pregnancy. Use air purifiers at home if you live near heavy traffic. Choose low-traffic routes for walking. Browse non-toxic baby products for a safer pregnancy environment.
