The largest July 4 fireworks display in Washington D.C. left the city under a "Code Purple" air alert on July 27 [1], indicating poor air quality caused by large amounts of smoke and fine particles released during the event. This follows similar issues reported in Southeast Michigan, where residents faced an unhealthy air quality range due to wildfires and a continuing heat advisory on July 31 [2]. In Michigan, a statewide air quality alert was issued for Sunday and Monday [3] because of wildfire smoke. Philadelphia also experienced reduced air quality alerts as a result of wildfire smoke, with health officials urging caution despite the downgrade from a code red alert [4].
