What started as a University of Washington-led project to measure air pollution near Sea-Tac International Airport has led to schools in the area installing portable air filters to improve indoor air quality. First, UW researchers found they were able to parse aircraft pollution from roadway pollution in the communities under Sea-Tac International Airport flight paths and map the air quality impacts of the ultrafine particles associated with planes. Then they discovered that the mix of ultrafine particle pollution, black carbon…
