A new study shows air pollution like soot, dust and smoke is down around the country with one exception: wildfire prone areas like the Mountain West.
Dan Jaffe is an environmental chemist and researcher on the study. He said implementation of the Clean Air Act is largely responsible for air pollution going down in the United States overall. But in the West, we’re seeing worsening air quality because of wildfire smoke.
The study shows the region that’s most being affected by smoke and by deteriorating air quality is northern California, Nevada, Oregon, eastern Washington, parts of Utah, parts of Colorado, almost all of Idaho, all of Montana, and all of Wyoming.
Jaffe says this is a concern because it’s affecting people’s health in the West and because it’s part of a larger pattern.
“It’s all related back to climate change,” he said, “and how we manage our forests.”
Wildfires have already ravaged areas of the Mountain West this summer and other areas are still on high alert.
