Smoke from California wildfires obscures the view of Strip casinos in this view taken from I-15 and Warm Springs Road Sunday, July 24, 2016.

Clark County’s Department of Air Quality has issued an advisory for today and Tuesday for potentially elevated levels of ozone and smoke from a wildfire north of Los Angeles.

Conditions may be unhealthy for people most sensitive to smoke and ozone, including those with respiratory problems and cardiac disease, young children and seniors, officials said.

Smoke is made up of small dust particles and other pollutants that can aggravate respiratory diseases and contribute to the formation of ground-level ozone.

At ground level, ozone, a gas that occurs naturally in the upper atmosphere, is a key ingredient of smog. It can build up during the afternoon due to a combination of factors, including strong sunlight, high temperatures and pollutants from cars and wildfires.

The DAQ website has detailed information on air quality conditions.

County officials offered the following recommendations for those sensitive to smoke and dust:

• Limit outdoor exertion, which increases the amount of particulates inhaled.

• Keep windows and doors closed, and run air conditioners in the house and car. Air conditioning filters out dust and particles.

• Change indoor air filters if they are dirty.
