An air quality advisory has been issued for Sunday and Monday due to smoke from wildfires in Southern California.
Clark County Department of Air Quality officials say smoke is made of small dust particles and other pollutants that can aggravate respiratory diseases and contribute to ground-level ozone formation.
Air quality monitoring staff believe the primary sources of the smoke are the Key Fire in Santa Barbara County, the Chimney Fire in San Luis Obispo County and the Soberanes Fire in Monterey County.
At this time, “unhealthy for sensitive groups” levels of ozone and particulate matter are not occurring. People who may be most sensitive to elevated levels of ozone and fine particles include individuals with respiratory problems, cardiac disease, young children or senior citizens.
Clark County Air Quality officials will continue to monitor conditions and will post an update on the forecast page of the DAQ website. The website also contains data on current and past conditions.
