LAS VEGAS — Clark County’s Department of Air Quality has issued a season-long advisory for ozone. The County’s ozone season starts in April and lasts through Sept. 30.

“We need to remain vigilant in our efforts to reduce ozone pollution,” said Lewis Wallenmeyer, Director of the County’s Department of Air Quality. “As the weather warms up, ozone pollution becomes a concern throughout the spring and summer months in the Las Vegas Valley.” Ozone concentrations in Valley are close to exceeding the 2008 National Ambient Air Quality Standard.

At ground level, ozone is a key ingredient of urban smog during the hottest months of the year. Sources that contribute to the formation of ozone pollution include automobile exhaust, regional wildfires and pollutants transported from other areas.

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, officials advise everyone to limit strenuous outdoor activity.

Other ways to help reduce ozone pollution include:

• 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.
• Turn off lights and electronics when not in use. Less fuel burned at power plants means cleaner air.
• Consider low-maintenance landscaping that uses less water and doesn’t require the use of gas-powered lawn tools to maintain.

Residents can sign up for free text and e-mail advisories and air quality forecasts through the department’s EnviroFlash service. The department also posts daily air quality reports and forecasts on its website.
