Exposure to diesel exhaust during pregnancy or in the early years of development could cause subtle changes in the structure of the cerebral cortex similar to those seen in the brains of autistic patients.
A group of 15 air pollution experts—including three scientists from the UW Department of Environmental & Occupational Health Sciences (DEOHS)—say recent changes made by the US Environmental Protection Agency (EPA) have damaged the quality and credibility of the EPA’s scientific review process for federal clean air standards.
As Central Washington became choked with wildfire smoke last summer, Dr. Mark Larson grew so concerned about air quality measures in Kittitas County that he couldn’t sleep for 10 days.
As the health officer for Kittitas County, Larson felt it was his duty to recommend canceling outdoor activities. But as a 20-year community resident, he also knew that the Kittitas Rodeo was right around the corner—a nationally known event that can bring in more than $8 million to the local economy in a single weekend.

For the past two summers, the western part of the United States has experienced extraordinary wildfire seasons.
Dominated by longer burns, fires in locations not previously thought to be at risk, and significant smoke in dense urban areas, these events were a wake-up call to communities with little or no experience dealing with them.
The Pacific Northwest’s “new normal” is starting to feel like old normal in Washington’s Methow Valley.
This is the fifth summer in a row that wildfire season has hit the Methow Valley especially hard, causing hazardous smoke conditions that persist for weeks and leaving residents feeling trapped and isolated.
Cooped up inside, valley residents can get a little stir-crazy as they watch summer drift by in a haze. The alternative—wearing a mask to go outside—only adds to the sense of apocalypse.
We’re learning more all the time about the health risks of breathing dirty air—and the news is alarming.
At the Western Hemisphere’s busiest land border crossing, tens of thousands of vehicles wait each day, engines idling, to cross between San Diego and Tijuana, Mexico.
Researchers know that the 30,000 residents of San Ysidro, on the US side of the crossing, live with spikes in air pollution, higher levels of asthma and other negative effects from those car emissions.
But what’s happening just across the border in Tijuana, one of Mexico’s largest cities?
I see toxic chemicals everywhere.
It’s an occupational hazard for me as a toxicology PhD student in the UW Department of Environmental & Occupational Health Sciences. I spend my days learning and writing about all things environmental health, so naturally, I’m worried about my own exposures to the pollutants around us.

She never anticipated that one day, she would have to choose between them.
