The Clark County Department of Environment and Sustainability (DES) is extending an advisory through September 21 for elevated levels of smoke due to regional wildfire smoke expanding into the southwest U.S., including southern Nevada. DES Division of Air Quality officials say smoke will be aloft with lingering smoke in the Las Vegas valley.
Smoke is made of small dust particles and other pollutants that can aggravate respiratory diseases and contribute to ground-level ozone formation. Smoke and other pollutants can aggravate respiratory diseases such as bronchitis and asthma or heart disease. Consult your physician if you have a medical condition that makes you sensitive to air quality conditions. Under today’s conditions, it may be best for children, the elderly and people with respiratory and heart disease to stay indoors.
