A comprehensive study measuring ultrafine particles, lead, and other air pollutants from aviation emissions at Hanscom Field across four surrounding Massachusetts towns. The study found that UFP concentrations were up to two-fold higher at downwind sites and often exceeded WHO guidelines, with the highest impacts in Bedford and Lexington.

A 2023 Tufts University study examined how living near major airports like LAX exposes millions of Americans to harmful levels of noise and air pollution. Research links this proximity to higher rates of hypertension, cardiovascular disease, poor learning outcomes in children, and emerging evidence of pre-term birth and brain cancer. With over 33 million people living within 10 miles of the 23 busiest U.S. airports, the findings carry significant public health implications for communities near facilities like Sea-Tac.

A peer-reviewed study by researchers from Tufts, UCLA, USC, and the University of Washington found that mothers living near airports and exposed to ultrafine particles from jet exhaust face elevated rates of preterm birth. The research, published in Environmental Health Perspectives in 2020, is particularly relevant to communities near large airports like Sea-Tac, where millions of residents live within the impact zone of aircraft emissions. The findings carry significant environmental justice implications, as near-airport communities with high pollution exposure are often among the most vulnerable populations.

This December 2016 presentation by University of Washington Professor Tim Larson examines ultrafine particles (UFPs) — tiny airborne particles smaller than 0.1 micrometers — found near airports, with a focus on emissions from aircraft and other combustion sources. Conducted in collaboration with researchers from UW and USC, the study explores how these microscopic particles, which are far smaller than diesel smoke or tobacco smoke particles, may pose environmental and health concerns for communities near airports like Sea-Tac. The research provides scientific context for understanding air quality impacts associated with airport operations.
