A wildfire at the Mexico-California border was one of the factors in an air quality advisory issued in Clark County on Wednesday.

The county’s Department of Air Quality said the fire near Mexicali, a mulch pit fire northeast of the Las Vegas Valley, weather conditions and existing levels of pollutants prompted the advisory for ozone and smoke.

The department noted levels of air pollution were not present but alerted residents about the possibility of unhealthy levels.

According to the county, unhealthy doses of ground-level ozone can build during the afternoon hours. The combination of strong sunlight, hot temperatures and pollutants from automobiles and other sources contribute to ozone.

Officials urged residents to monitor air pollution levels at redrock.clarkcountynv.gov/forecast.

Officials also advised residents to limit strenuous outdoor activity when ozone levels are elevated. In addition, residents were advised to reduce ozone pollution with the following:

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.
