Urban Wildfires in LA Pose Long-Term Health Risks
In January 2025, the Palisades and Eaton fires devastated Los Angeles County, scorching over 150 square kilometers. These urban wildfires, burning through homes and infrastructure, posed unique threats and raised concerns about long-term health risks.
During the fires, ASCENT stations recorded alarmingly high levels of lead, chlorine, and bromine. Inhaling smoke from these fires, or particles stirred up during cleanup, can lead to serious health issues, including increased cancer risks over time. This is due to hazardous components like volatile organic compounds (VOCs) and particulate matter (PM), with about 90% of wildfire smoke particles being PM2.5, small enough to enter the bloodstream.
Real-time air quality maps, provided by the South Coast AQMD and U.S. EPA, offer year-round data, with more detailed information from permanent monitoring stations. However, the search for specific researchers involved in studying air quality during these fires yielded no results.
The Palisades and Eaton fires highlighted the severe health risks associated with urban wildfires. While immediate threats were mitigated, long-term health impacts remain a concern. Further research is needed to fully understand and address these risks.
