In this Data Brief, the LA Fire HEALTH Study features preliminary data findings of indoor and outdoor air quality in the Palisades and Altadena areas.  

Key Takeaways:

• Localized air pollution PM measurements in Altadena and the Palisades are generally within EPA limits, are consistent with regional air quality monitors, and are considered typical for the region.
• Air quality measurements can vary significantly based on time of day, direction of wind, and atmospheric conditions. Therefore, it is best to err on the side of caution: if you smell smoke or chemicals when outside, even if the AQI is green for your area, consider wearing an N95 mask or holding off on outdoor activity until the smell dissipates.
