Michael Marshall from Paso Robles and Dalton Smith from Templeton watched the vibrant fireworks display over Huntington Beach on July 4, 2024. Los Angeles Times captured the moment as the sky lit up, marking the occasion with colorful celebrations across Southern California.
Southern California celebrates Fourth of July with numerous fireworks displays. Official and unofficial pyrotechnics events are common, but behind every sparkler lurk air pollutants. These pollutants include noxious gases, soot, and toxic metals that settle in the lungs of people nearby.
The South Coast Air Quality Management District warned of unhealthy air quality from fireworks. Central and southern Los Angeles County, northern Orange County, Riverside, and San Bernardino counties would see increased pollution levels. Light winds may exacerbate the situation, causing smoke from fireworks to linger from Saturday evening till Sunday afternoon.
According to Los Angeles County Public Health, pollutants can harm respiratory and cardiovascular health. Asthma flares, coughs, and heart attacks are potential risks. If cardiovascular symptoms worsen, seek medical help immediately.
Home pyrotechnics pose heightened health risks, per the American Lung Association. Pollutants burst closer to the ground, increasing exposure.
Traditionally, July 4 and 5 have poor air quality in Southern California. This year’s event followed a significant warehouse fire in Boyle Heights, which produced large amounts of soot and smoke similar to past wildfires.
To reduce health risks, Los Angeles County advises avoiding physical activities and keeping homes sealed. Use air purifiers or air conditioners to minimize indoor pollution. Fans and swamp coolers might draw more pollutants inside.
