The Pocatello area is now the 25th most polluted area for short-term particle pollution in the United States, and across Idaho air quality is getting worse, according to the American Lung Association’s 2019 “State of the Air” report.

The report tracked short-term spikes in particle pollution, as these can be extremely dangerous and even lethal. Pocatello experienced more days on average of spikes in particle pollution and many of these spikes in were directly linked to events like wildfires, which are increasing in frequency and intensity in many areas due to climate change.

“People living in Pocatello should be aware that we’re breathing unhealthy air, and much of this unhealthy air is driven by wildfires that are a result of climate change, placing our health and lives at risk,” said Heather Kimmel, Health Promotions Director for the American Lung Association in Idaho. “In addition to challenges here in Pocatello, the report shows that more than four in 10 Americans live with unhealthy air, and must do more to protect public health.”

In the rest of the state, the Logan UT-ID area and Spokane Valley/Coeur d’Alene areas rank as the 11th and 15th most-polluted areas respectively in the nation respectively for short-term particle pollution, worse than last year. Bannock County received an “F” grade for short- term particle pollution, and Lemhi and Shoshone counties ranked 15th and 17th most-polluted for annual particle pollution respectively.

Each year the “State of the Air” provides a report card on the two most widespread outdoor air pollutants, ozone pollution, also known as smog, and particle pollution, also called 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 increase the risk of premature death and other serious health effects such as lung cancer, asthma attacks, cardiovascular damage, and developmental and reproductive harm.

“Particle pollution is made of soot or tiny particles that come from coal-fired power plants, diesel emissions, 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, and can even be lethal,” said Kimmel.

While the report examined data from 2015-2017, this 20th annual report online provides information on air pollution trends back to the first report. Learn more about air quality rankings at For media interested in speaking with an expert, contact Holly Harvey at [email protected] or 206-512-3292.
