VENTURA — The Ventura County Air Pollution Control District is issuing an Air Quality Alert because of unhealthy air quality conditions caused by the Canyon Fire. Impacted areas may include, but are not limited to, Piru, Fillmore and Santa Paula.
Smoke from the Canyon Fire has caused air quality to fall into the unhealthy range for the general population, as measured by the U.S. Environmental Protection Agency Air Quality Index (AQI). Smoke and ash from wildfires contain very small particles — particulate matter with a diameter of 2.5 micrometers or less — that can harm the lungs and heart.
