LAS VEGAS (AP) - The American Lung Association says Las Vegas has some of the worst air pollution in the country, but it's getting better.
High ozone pollution the past year earned Clark County an "F'' in the group's annual "State of the Air" report released on Wednesday. It says valley smog levels now rank as the 16th worst in the nation.
Nevertheless, Amy Beaulieu, director of the American Lung Association's programs in Nevada, tells the Las Vegas Review-Journal that the air in Las Vegas is certainly cleaner than it was when the first report came out 14 years ago.
Among the other Nevada counties reviewed, Churchill got an "A'' and Washoe a "C." Carson City, Lyon and White Pine counties all got a "B."
