Smoke from wildfires burning across California and Arizona as well as local July 4th fireworks and barbeques prompted Clark County officials to issue an air quality advisory through Saturday.
Clark County Department of Air Quality and Environmental Management officials urged people with lung and heart conditions to watch air quality conditions each day. Infants, children, senior citizens and those with chronic health problems are most susceptible.
"We could have a more intense set of circumstances with smoke from wildfires, fireworks and barbeques all happening concurrently," said Phil Wiker, the department's meteorologist.
At this time, unhealthy levels of air pollution are not occurring in Southern Nevada.
However, hot summer months raise ozone at ground level and smoke contributes to the formation of a brownish cloud of smog, Wiker said.
Local air quality officials recommend that workers outdoors wear a painter's or surgical mask to help reduce exposure to dust and particles.
Limiting outdoor exercise is also recommended and staying indoors with air conditioner running at your home, office and car, Wiker said.
Before Friday's holiday, those who need prescription allergy medications or over-the-counter hay fever or sinus medications are advised to have enough on hand to handle itchy eyes, a runny nose or congestion.
