Smog Chamber: Understanding the Chemistry of Air Pollution

The image shows a detail of the photochemical aging chamber built by Richard Peltier, an atmospheric chemist in the Department of Public Health. The compartment is surrounded by UV light, which serves to simulate how sunlight ages air pollutants over time. The chamber allows Peltier to measure the toxicity of pollutants and look for patterns in the photochemical oxidation, or “aging” process. The research is part of an ongoing project aimed at investigating the effects of air pollution on cardiovascular health. Learn more.
