Ozone exposure study reveals how pollution harms lungs
NCT ID NCT02673775
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how breathing in ozone, a common air pollutant, affects immune cells in the lungs. 135 healthy adults were exposed to both clean air and low-level ozone, and their sputum was tested for changes in macrophage activity. The goal was to better understand the early steps of lung injury from air pollution.
