Seasonal Ozone Advisory Issued Through Sept. 30
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 September 30.
“We have made tremendous progress on improving air quality in the Las Vegas Valley over the years, but ozone pollution continues to be a challenge, particularly during daytime hours in the spring and summer months when the combination of strong sunlight, hot temperatures and pollutants from cars aid in its formation,” said Marci Henson, Director of the County’s Department of Air Quality.
At ground level, ozone is a key ingredient of urban smog during the hottest months of the year. Sources that contribute to the creation 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. The public can help reduce ozone pollution by limiting activities that burn fuel, especially on days when ozone levels are high. Suggestions include:
• Use mass transit or carpool.
• Plan errands so they can be done in one trip.
• Keep your car well maintained.
• 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.
• Limit the use of outdoor fireplaces, grills and fire pits, particularly during daytime hours.
• Try not to spill gasoline when filling up and don’t top off your gas tank.
• Fill up your gas tank after sunset.
