Another fireworks hazard: Pollution
L.A. County advises residents to avoid outdoors until air improves
First came an earth-rattling temblor and then a massive display of July Fourth fireworks. Now, residents of Southern California are sharing yet another collective experience — bad air quality.
Along with the usual Independence Day-related injuries and hangovers, July 4 and 5 bring some of the worst air pollution of the year. Friday was no exception as officials issued an air quality advisory.
“When I woke up this morning to head for work, I immediately felt the difference,” said bicycle courier Melvin Sosa, 20. “The air was way too warm, plus it felt a little harsher to breathe through the day.”
Fireworks release metal air pollutants and toxic particulate matter known as PM2.5 and PM10 that contribute to L.A.’s existing pollution, according to the South Coast Air Quality Management District. The pyrotechnics increased air pollution in Los Angeles County, with many areas reaching hazardous levels.
“People with heart or lung disease, older adults and children should avoid all physical activity outdoors,” the Los Angeles County Department of Public Health said. “Everyone else should avoid prolonged or heavy exertion.”
According to the health department, pollution within the San Gabriel Valley and East San Gabriel Valley are expected to reach levels hazardous to all residents. In downtown Los Angeles, southeast Los Angeles County and Santa Clarita Valley, conditions would mostly affect children, the elderly, and those with health conditions such as heart disease and asthma.
The state Air Resources Board predicts the fireworks haze will begin to clear out by Sunday, due to increasing winds. But anticipated highpressure conditions next week will set the stage for poor air conditions again.
