Description
Sun Li and five co-authors study whether a mother's weekly exposure to airborne particles during pregnancy raises the risk of congenital heart disease in her baby. Their study came out in 2025. Earlier work linked air pollution to these heart defects, but the critical weeks of exposure were poorly mapped.
The team followed nearly twenty thousand pregnancies with full delivery records in one Chinese city, matched to daily pollution data. Models that account for timing found that exposure to larger particles raised risk during two windows. The first window covered the early weeks when the heart forms, and the second fell in mid-pregnancy. The strongest signal appeared in the very first weeks studied. No consistent link appeared for the finest particles. The authors call for confirmation in further studies.
