LOS ANGELES, CA — In the aftermath of Fourth of July celebrations and glittering fireworks shows, health officials warned Pasadena residents about the hazardous air quality that fireworks bring.
According to the South Coast Air Quality Management District, particle pollution peaks every year on July 4 and 5. The hazardous conditions can lead to a variety of cardiovascular and respiratory health effects such as heart attacks, asthma aggravation, decreased lung function, coughing or difficulty breathing.
In some extreme cases, the pollution could lead to premature death in people with heart or lung disease, the AQMD said.
