Air Quality Advisory Issued for Smoke/Ozone Through Sunday 

The Clark County Department of Air Quality (DAQ) has extended the advisory for smoke and ground-level ozone due to wildfires in the region.

The advisory remains in effect through Sunday and could be extended into next week. The location of the wildfires may be viewed here: http://activefiremaps.fs.fed.us/index.php.

Smoke is made of small dust particles and other pollutants that can aggravate respiratory diseases, and contribute to ground-level ozone formation. Air Quality officials will continue to monitor conditions and will post an alert on the forecast page of the DAQ website if unhealthy levels are detected. A link to the forecast page is located at http://redrock.clarkcountynv.gov/forecast/.

Smoke and high temperatures also contribute to higher levels of ground-level ozone. Ozone is a gas that occurs naturally in the upper atmosphere and protects the earth from the sun’s harmful ultraviolet rays. At ground level, ozone is a key ingredient of urban smog during the hottest months of the year in Clark County. Ground-level ozone can build up during the afternoon hours due to a combination of several factors including strong sunlight, hot temperatures, and pollutants from automobiles and other sources such as wildfires and pollution from nearby regions. Unhealthy doses of ground-level ozone can reduce lung function and worsen respiratory illnesses such as asthma or bronchitis. Exposure to ozone also can induce coughing, wheezing and shortness of breath even in healthy people. When ozone levels are elevated, everyone should limit strenuous outdoor activity, especially people with respiratory diseases.  If you are experiencing breathing difficulties or medical conditions that you think are related to air quality, see your doctor.  

Officials suggest these tips to help reduce the formation of ground-level ozone:

  • Fill up your gas tank after sunset.
  • Plan errands so they can be done in one trip.
  • Try not to spill gasoline when filling up, and don’t top off your gas tank.
  • Keep your car well maintained.
  • Use mass transit or carpool.
  • Don’t idle your car engine unnecessarily.
  • Walk or ride your bike whenever practical and safe.
  • Consider low-maintenance landscaping that uses less water and doesn’t require the use of gas- powered lawn tools to maintain.
  • Turn off lights and electronics when not in use. Less fuel burned at power plants means cleaner air.

ADDITIONAL INFORMATION:

Airborne smoke/dust is a form of inhalable air pollution called particulate matter, or PM, which aggravates respiratory diseases such as bronchitis and asthma. It may be best for children, the elderly, and people with respiratory diseases to stay indoors.

Other suggestions include:  

  • If you work outdoors, consider wearing a painter’s mask or surgical mask. This will help reduce your exposure to dust and particulates.
  • Limit outdoor exertion. Exercise, for example, makes you breathe heavier and increases the amount of particulates you are likely to inhale.
  • Keep windows closed. Run your air conditioner inside your house and car. Your air conditioner filters out dust and particulates.
  • Consider changing your indoor air filters if they are dirty.
  • Use your prescription allergy medication or over-the-counter hay fever or sinus medications if you experience symptoms of itchy eyes, a runny nose, or congestion.

Detailed air quality conditions are posted in the monitoring section of the DAQ website. You can receive free air quality forecasts and advisories via e-mail or text message through Enviroflash service. Subscription information is available at www.enviroflash.org.
