D.C. Air Quality After Fourth of July Fireworks | Washington DC News

DC’s Fourth of July fireworks turned into a public health emergency as air quality plummeted to record lows, triggering a Code Red alert and exposing deeper, year-round pollution problems. PM2.5 levels spiked sixfold, lingering for hours before rain helped clear the smoke. Compounded by a heat dome that boosted ground-level ozone — a lung irritant linked to car exhaust and UV rays — the city’s air quality woes are persistent. Despite progress in cutting pollution, D.C. still fails federal standards and earns poor marks from health groups. With nearly 200,000 residents suffering from respiratory or heart conditions, officials are ramping up monitoring, inspecting polluting sources, and pushing for cleaner vehicles and products — but the fight to breathe easy is far from over.
