NCT ID NCT04068389
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study examined whether tiny air pollution particles inhaled by a pregnant woman can cross the placenta and reach her unborn baby's lungs. Researchers collected lung tissue from 62 fetuses after medical termination of pregnancy (over 22 weeks) and used electron microscopy to check for particles. The goal is to understand how early in life pollution exposure may begin.
