A University of Washington thesis by Mariah Dittmore investigates whether short-term exposure to ultrafine particles from aircraft engines causes measurable cardiorespiratory harm at concentrations found in surrounding communities, and whether personal protective equipment can reduce that harm. The research builds on a 2018 Los Angeles study that linked walking near aircraft pollution to elevated blood inflammation markers, while noting that roadway traffic posed its own distinct respiratory risks. The findings are relevant to policy discussions around Seattle-Tacoma International Airport and the health of workers and residents exposed to aircraft emissions.
