Fireworks Smoke Triggers Air Quality Alert in DC Region

The National Mall fireworks show in Washington, DC, has left behind lingering smoke and triggered air quality alerts, with a "Code Orange" forecast through Thursday. The pollution from the fireworks and ground-level ozone have contributed to unhealthy air quality, particularly for sensitive groups. The region was initially under a "Code Red" alert, which was later downgraded to a "Code Purple" before being downgraded again. People are advised to limit time outside and check the current air quality.
