Wu study is subject of NatGeo article

A new study by AirUCI faculty Jun Wu and cited in an article in National Geographic measures the impact of fireworks on air quality and population health. Fireworks produce colorful, crackling light displays but they also create smoke. It’s less widely known that the smoke can be dangerous due to their particulate matter, which can be an asthma trigger and a leading contributor to respiratory disease as well as a cocktail of toxic metals like strontium, barium, and lead. While the pollution from a single fireworks display tends to dissipate quickly, many fireworks being set off over the Fourth of July can cause regional air pollution levels to spike and remain elevated for several days, posing a potentially serious health risk to vulnerable populations.  Read the article
