Seasonal Ozone Advisory Issued Through September

The Clark County Department of Environment and Sustainability issued a season-long advisory for ground-level ozone pollution today that will be in effect from Thursday, April 1 to Thursday, Sept. 30.

Ozone is a colorless gas that exists naturally in the Earth’s upper atmosphere. At ground level, ozone is a key ingredient of urban smog that can build up during the day in the hottest months of the year because of strong sunlight, hot temperatures, gasoline and chemical vapors, and pollutants from automobiles, wildfires and regional transport. Exposure to ozone can irritate your respiratory system and cause coughing, a sore throat, chest pain and shortness of breath even in healthy people, according to the EPA.

“Even though wildfire smoke throughout the western United States played a big part in Clark County’s ozone exceedances two of the past three years, it’s important we do everything we can at the local level to reduce ozone-producing pollutants, such as vehicle emissions and industrial pollutants,” said Department of Environment and Sustainability Assistant Director Jodi Bechtel. “Our Air Quality Division continues to enforce all federal, health-based standards to keep pollutants in check. People who live here also play an important role in reducing ground-level ozone. How often we drive, when we refuel our vehicles and how fuel-efficient our vehicles operate have an impact on local air quality.”

HELPFUL TIPS TO REDUCE OZONE

Because cars, trucks and other vehicles are major contributors to ozone, people can follow these helpful, everyday tips to reduce ozone:

  • Reduce driving – combine errands into one trip.
  • Don’t idle your car engine unnecessarily.
  • Use mass transit or carpool.
  • Fill up your gas tank after sunset. Try not to spill gasoline when filling up and don’t top off your tank.
  • Keep your car well maintained.
  • Consider landscaping that uses less water and gas-powered equipment to maintain.
  • Turn off lights and electronics when not in use. Less fuel burned at power plants means cleaner air.

 Also, if you have respiratory issues or other health concerns, consider these tips during ozone season:

  • Reduce the time you are active outdoors when ozone levels are elevated, especially if you are engaged in a strenuous activity or have a respiratory disease.
  • Schedule activities for the morning or evening when ozone levels are usually lower.
  • Substitute a less intense activity – walking instead of jogging, for example.
  • Always consult your doctor first for medical advice.
