Air quality advisory issued

Smoke from the Lake Fire west of Lancaster, California, came into the valley Thursday, resulting in an advisory about air quality from the Clark County Department of Environment and Sustainability.

The Lake Fire had burned 10,500 acres as of 9 a.m. Thursday while the two-week-old Apple Fire in the same region had charred more than 33,000 acres and was 80% contained, according to Cal Fire.

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

According to the U.S. Environmental Protection Agency, people who may be most sensitive to elevated levels of particulates and ozone include individuals with respiratory problems, cardiac disease, young children or senior citizens. Consult your physician if you have a medical condition that makes you sensitive to air quality conditions.
