Pasadena Public Health officials have declared a local health emergency due to the impacts of recent wildfires, particularly the Eaton Fire, affecting air quality across Los Angeles. Residents are facing serious health risks from toxic wildfire smoke, which has been found to contain harmful particle pollution. Experts are warning that long-term exposure to this smoke, compounded by the presence of windblown fire ash, can pose significant health hazards. As Santa Ana winds exacerbate the situation, health warnings have been issued, urging individuals to wear masks and take precautions against smoke inhalation. Residents are advised on how to clean up ash safely, while health officials highlight that the dangers of wildfire smoke may not be accurately reflected in air quality maps. The community is responding with increased sales of air filters and masks as they seek ways to protect themselves from the hazardous conditions. With air quality concerns persistent, officials stress the importance of understanding the health implications associated with the ongoing wildfire situation.
