‘State of the Air’ 2017 Report Finds Las Vegas Air Quality Improved
Despite continued improvement in U.S. air quality, local residents remain at risk from health effects of unhealthy air according to new report from the American Lung Association
(April 19, 2017) -
The American Lung Association’s 2017 “State of the Air” report found that while Clark County earned failing grades in ozone and short-term particle pollution, the average number of unhealthy days improved in both categories. The county saw a rise in long-term particle pollution; however, its levels are still well below the national average.
The Las Vegas-Henderson area improved its ozone levels, experiencing its fewest unhealthy days and bettered its ranking to 10th most polluted in the nation. The area also improved its short-term particle pollution ranking to 37, keeping in line with a national trend. Clark County earned an F for its ozone pollution and D in short-term pollution.
“The 2017 ‘State of the Air,’ report found continued improvement in air quality across the country, but 40 percent of Americans still live with unhealthful levels of either ozone or particle pollution placing their health at risk,” said Kristina Crawford, executive director of the American Lung Association in Nevada. “Even though Las Vegas saw improvements from last year’s report, residents are still exposed to high levels of pollution, which can put them at risk for premature death and other serious health effects such as asthma attacks, worsened chronic obstructive pulmonary disease (COPD) symptoms and cardiovascular harm. Our high levels of year-round particle pollution also place our citizens at greater risk for lung cancer.”
Across the state, Reno’s rakings for short-term particle and ozone pollution worsened, with the area tying at 10 and 36, respectively. However, Reno did see improvements for year-round particles, ranking at 60th most polluted.
The most notable national findings of the 18th annual report were lower overall ozone levels and lower year-round particle levels, offset by a continued trend of extreme short-term spikes in particle pollution, often related to wildfires or droughts. The report finds that the health of 43 million people across the country are at risk from these dangerous spikes in particle pollution.
Each year the “State of the Air” reports on the two most widespread outdoor air pollutants, ozone pollution (smog) and particle pollution (soot). The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution. Both ozone and particle pollution are dangerous to public health and can be lethal. But the trends reported in this year’s report, which covers data collected by states, cities, counties, tribes and federal agencies in 2013-2015, are strikingly different for these pollutants, nationwide, and in Las Vegas
Ozone Pollution in Las Vegas
Compared to the 2016 report, Las Vegas experienced its fewest unhealthy days of high ozone ever in this year’s report. Nationwide, ozone pollution has decreased, thanks to the Clean Air Act’s success at cleaning up major sources of the emissions that create ozone, especially coal-fired power plants and vehicles. However, research shows that climate change causes warmer temperatures, which makes ozone harder to clean up.
“Ozone is harmful to public health and especially children, older adults and those with asthma and other lung diseases. When they breathe ozone-polluted air, too often they end up in the doctor’s office, the hospital or the emergency room,” Crawford said.
Particle Pollution in Las Vegas
“State of the Air” 2017 found year-round particle pollution (soot) levels in Las Vegas during 2013-2015 were slightly higher than the previous year’s report, but still below national air quality standards. Nationwide, the best progress in this year’s report came in reducing year-round levels of particle pollution.
Particle pollution is made of soot or tiny particles that come from coal-fired power plants, diesel engines, wildfires and wood-burning devices. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks and strokes. They can even cause lung cancer, and early death.
“Across the country, year-round particle pollution levels have dropped thanks to the cleanup of coal-fired power plants and the retirement of old, dirty diesel engines,” Crawford said.
Short-term spikes in particle pollution can be extremely dangerous and even lethal. According to the 2017 report, Clark County had fewer days when short-term particle pollution reached unhealthy levels in 2013-2015. This is contrast to the national trend of increased short-term spikes in particle pollution.
Climate is known to cause increased heat, changes in weather patterns, drought and wildfires, which contributed to the extraordinarily high numbers of days with unhealthy particle pollution in some cities, including Las Vegas. Many of these spikes throughout Nevada were directly linked to weather patterns and events, such as wildfires, which are likely to increase because of climate change.
“Healthy air protections are under attack, and must be defended to save lives here and across the country. Air travels from one state to another, so only federal protections can help protect the air we all breathe,” Crawford said. “The Lung Association in Nevada calls on President Trump, EPA Administrator Scott Pruitt and members of Congress to fully fund, implement and enforce the Clean Air Act for all air pollutants – including those that drive climate change and make it harder to ensure healthy air for all Americans.”

About the American Lung Association in Nevada
The American Lung Association is the leading organization working to save lives by improving lung health and preventing lung disease, through research, education and advocacy. The work of the American Lung Association is focused on four strategic imperatives: to defeat lung cancer; to improve the air we breathe; to reduce the burden of lung disease on individuals and their families; and to eliminate tobacco use and tobacco-related diseases.
