County dust advisory
The Clark County Department of Environment and Sustainability has issued a dust advisory for Sunday to advise residents and local construction sites of the possibility of elevated levels of blowing dust.
“Airborne dust is a form of inhalable air pollution called particulate matter or PM, which aggravates respiratory diseases,” the advisory states. “Under windy conditions people with heart or lung disease, older adults, and children may feel better staying indoors as much as possible because they could be at greater risk from particulates, especially when they are physically active, according to the U.S. Environmental Protection Agency.”
Residents are asked to consult their physician if they have a medical condition that makes them sensitive to air pollution.
