Clark County issues air quality advisory, with nod to ozone effects

It’s that time of year again.

Officials have issued an air quality advisory, effective through Sept. 30, related to ground-level ozone in Southern Nevada.

Weather conditions and pollutants could trigger a buildup of ground-level ozone, which can cause urban smog during the hottest months of the year, according to the Clark County Department of Air Quality.

No unhealthy levels of ozone pollution have been reported at this time, officials said.

Ozone, a gas that occurs naturally in the upper atmosphere, protects the earth from the sun’s harmful ultraviolet rays. Strong sunlight, hot temperatures and pollutants from vehicles and wildfires cause a buildup of ground-level ozone during the afternoon hours.

Ground-level ozone can reduce lung function and worsen respiratory illnesses such as asthma and bronchitis, officials said. Healthy people also can experience coughing, wheezing and shortness of breath.

To reduce the formation of ground-level ozone, officials suggested:

Fill gas tanks after sunset.

Don’t spill gasoline when filling up and don’t top off the tank.

Run errands in one trip.

Don’t unnecessarily idle car engines.

Consider low-maintenance landscaping that doesn’t require gas-powered lawn tools to maintain.

Turn off lights and electronics when not in use.

Air quality conditions will be posted in the monitoring section of the Department of Air Quality’s website.

  1. I've been making and selling ozone generators for 10 years (foreverozone brand) and never cease to be amazed at the misinformation that the gov spews out regarding ozone and the amount of ignorance in general regarding ozone. The driving factors of this misinformation in my opinion? 1) Gov is "big industries" whore. The "polluters" have the money and own our elected officials in DC. They want to draw attention away from the real causes of pollution (industry) and place the blame on mother natures pollution eliminator - ozone. The head of the EPA once said she prays for the day when we can eliminate ground level ozone from the earth. If she were able to get her wish, we'd all die of course, but hey, who cares, at least we wouldn't be able to "say hello to the bad guy" any more, right? 2) Drug companies don't want people to know that ozone kills cancer. It's used in Europe to treat cancer without any side effects and more effectively than "Western Medicine". Drug companies PR people are undoubtedly behind the vilification of ozone to protect their cash cow, cancer drugs.

    Now here's the truth. Ozone (three oxygen atoms) is created by nature to break down and "get rid of" pollution whether it's from industry, forest fires, or volcano's. When pollution comes in contact with the sun's rays, oxygen atoms (o2) is split. The free oxygen atom attaches to O2 to create o3. The extra O atom then jumps off the o2 and breaks down the pollution mainly by breaking the hydrogen bonds. (simple version) While it's true that when there is a lot of pollution from older buses and trucks in the air their is a lot of ozone that is created to clean it up, to call ozone "pollution" instead of they hydocarbons and other man made pollutants is just a ploy to draw attention away from the real polluters.

    Ozone is natures air cleaner. It's used in industry to purify water without he use of toxic chlorine. It's used in unoccupied homes to disinfect surfaces, get rid of odors, and remove second hand smoke (or any smoke) damage. In low levels it's been shown to promote good health (less sick days in office buildings that employ ozone air purifiers in their HVAC system to prevent bacteria and virus airborne outbreaks. O-liminate Ozone? LOL. What morons. Why not eliminate the real people who cause air pollution, those who drive older trucks and buses EXEMPT from air controls? That would be too expensive? Okie dokie.
