It's a report that has no one in Clark County breathing easy.
The American Lung Association has released a report, State of the Air, that ranks air in Las Vegas and Henderson as the 10th most polluted in the country.
"I think the report accurately identifies the issues in terms of air quality in Clark County," said Russell Roberts with the Clark County Department of Air Quality.
Roberts said the report reflects improvements that have been made in reducing carbon monoxide particulates, but there's a nagging problem.
"The most difficult challenge we're going to have over the next five years is going to be with ozone," Roberts said.
Family physician Dr. Daliah Wachs said she sees a lot of patients complaining about difficulty breathing.
"We call it reactive airway disease. Whether they have asthma, COPD (chronic obstructive pulmonary disease) or are undiagnosed, we have people coming in saying they're a little bit short of breath. I've even noticed it," she said.
Wachs said there's a link between air pollution and many diseases and ailments.
"It's very interesting. A lot of people don't realize that a lot of this air pollution has been linked to diabetes, stroke risk, and now they even think it can be linked to autism," she said.
The report ranks the air in Los Angeles as the nation's worst.
