A study examining the effectiveness of portable HEPA filters in reducing ultrafine particles (UFPs) from aircraft and traffic sources in five schools near Sea-Tac International Airport. The research found that HEPA cleaners significantly reduced indoor UFP concentrations to one-half to one-tenth of outdoor levels. Atmosphere 2022: https://www.mdpi.com/2073-4433/13/10/1623

A 2021 scientific study found that global aviation contributes a small but meaningful share of human-caused climate change, primarily through carbon dioxide emissions and the formation of contrail clouds at high altitude. The research, covering the years 2000 to 2018, found that non-CO2 effects such as contrails account for roughly two-thirds of aviation's total warming impact. The findings are relevant to ongoing policy discussions about reducing the climate footprint of air travel.

A comprehensive review examining the cardiovascular health impacts of traffic noise exposure, with particular emphasis on nighttime noise effects. The study discusses WHO guidelines, mechanistic pathways involving oxidative stress and vascular dysfunction, and epidemiological evidence linking noise exposure to heart disease, stroke, and other cardiometabolic conditions.

Review article by Dean E. Schraufnagel published in Experimental & Molecular Medicine (2020) 52:311–317, DOI 10.1038/s12276-020-0403-3, examining the health effects of ultrafine particles (PM0.1, also called nanoparticles). Covers PM0.1 sources (traffic exhaust, welding, forest fires, cooking, tobacco smoke), absorption and retention in the lung, translocation to distal organs, pulmonary inflammation, metal fume fever, cardiovascular disease,

Research published in the Journal of the American College of Cardiology found that environmental noise from traffic, aircraft, and railways is linked to serious cardiovascular health risks, including high blood pressure, heart attack, heart failure, and stroke. Studies in both humans and animals show that aircraft noise — especially at night — triggers stress hormones and harmful oxidative stress in blood vessels, impairing their ability to function properly. These findings suggest that airport noise exposure is not just a quality-of-life issue but a measurable public health concern with direct effects on heart and vascular health.

This academic paper examines how U.S. federal agencies have addressed Environmental Justice (EJ) since President Clinton's 1994 Executive Order 12898, which required agencies to reduce disproportionate pollution burdens on low-income and minority communities. The author, a Bureau of Land Management social scientist, reviews agency compliance efforts, highlights case studies like the Flint water crisis, and argues that practical steps such as staff training and social science tools can help agencies consistently protect vulnerable communities regardless of shifting political priorities.

This 2011 doctoral dissertation by Linda Lyshall, submitted to Antioch University's PhD Program in Leadership and Change, examines how local-scale collaboration can drive climate action and environmental policy. The research explores the intersection of leadership, organizational behavior, and sustainability in addressing climate change at the community level. While not specific to Sea-Tac Airport noise policy, it may offer relevant frameworks for understanding collaborative governance and local environmental decision-making.

This engineering study describes the design and construction of a 46-meter (150-foot) tall mechanically stabilized earth (MSE) retaining wall built along the western edge of Seattle-Tacoma International Airport's third runway embankment, believed to be the tallest such wall in the western hemisphere at the time. The wall was necessary to raise the ground level by up to 50 meters while avoiding encroachment into nearby wetlands and creeks. Monitoring of the wall during and after construction confirmed it performed safely and largely as predicted.
