LAS VEGAS (AP) - A new report says the air pollution in Las Vegas ranks among the worst in the country.
The report by the Environment Nevada Research and Policy Center says the Las Vegas area had 145 days of poor air quality in 2016, a little higher than Los Angeles, which had 138 days of poor air quality.
KSNV-TV reports breathing degraded air quality can put people at risk for heart problems, asthma attacks and other adverse health problems that can affect people's lungs.
Experts in southern Nevada dispute the report and say the air quality in the Las Vegas area is not as bad as the report suggests.
Mike Sword with the Clark County Department of Air Quality tells KLAS-TV that air pollution in Las Vegas has actually been going down.
